Thoughts on Rennsport Factory custom performance parts?

[Benzy Boy]

There’s this company called rennsport factory in the uk that makes bespoke performance modifications for a lot of classic benz engines and transmissions including M119 performance parts.

For example they make custom camshafts, “plenum chamber,” and ITB for the M119.

I can’t find any reviews about them online or any videos of their products or dyno results.

Why would anyone want to put a custom plenum chamber on their M119? Or ITBs?

The custom camshaft might be worth inquiring about but I am skeptical.

 

[gsxr]

No dyno results? No sale. Period, full stop.

The ITB's shown in theory could make quite a bit more peak HP, or generally increase power at high RPM... at the expense of low-end & midrange torque. This would generally be desired on a race engine that spends all its life on the track, over 4000rpm after leaving the pits. Not something you'd want around town. But until there's some dyno graphs, and a good review of what it's like to drive with those ITB's installed (along with full aftermarket ECU), it's hard to say.

I can't find any info about M119 camshafts specifically, but their Faceplant page mentions "some" applications are simply regrinds - same as Hagmann and Dbilas have been doing for years. Note this post is from 2018 - they've had these "available" for 5+ years and not one person has before/after dyno results? Riiiiiight.

"We have a range of camshafts to cater for most Mercedes engines. Some of the earlier engines will require donor camshafts to be regroundand the kits available off the shelf are available in either steel billet or chilled cast depending on application. These will usually have 4-6 options, from road to full competition applications.​

​

M100 (6.3 and 6.9), M102 8v, M102 16v, M103, M104, M111, M112, M113, M117, M119, M120, M166, M137, M271, M272 and M275 are currently all available.​

​

Our performance road camshaft kit is designed to increase performance in the mid to upper RPM range. CNC machined from billet steel with profiles we’ve developed to create a bolt in kit achieving a large increase in lift and duration extracting maximum horsepower from the engine whilst keeping fitment simple, not requiring the use of upgraded valve springs.​

​

The fast road kit comes with upgraded valve springs and retainers which allow an increase in lift and duration over the performance road kit whilst still retaining the oem hydraulic lifters. This kit is ideal to match our ported heads or if the head(s) are being removed.​

​

The ECU will usually need remapping to achieve maximum power from a camshaft swap. Turbo specific profiles are available for most applications.​

The competition camshaft kit comes with a solid lifter conversion, in the case of the M112 and M113 we have an adjustable conversion kit by Mahle which requires the rocker to be converted to this mechanical lifter setup. We can carry out this process or supply the parts and instructions with the kit. With this conversion assuming you have the piston to valve clearance nearly any duration and lift can be supplied. We have 4 competition profiles already developed for each application which should cater for all requirements but we can take on custom projects."​

 

[anderzen]

unfortunately as cool as some of their concepts are, the follow through has been lackluster or non existent... not to mention it can be damn hard to form any consistent communication with them, often times left in the dark for weeks with simple questions awaiting a response.

I have buddies developing modular itb kits for the M104/113 and later M119 (just two college engineers in their spare time) who are making leaps and bounds more progress and will have fully functional results in less than a year since beginning. (Alumotive)

I think one of the biggest ploys in all of this is no mention of what they will use for tuning, you are not 'remapping' the stock 124 computers to do any of this lol...

 

[JC220]

I have communicated with this guy before and he is not pleasant to do business with! I was trying to buy a NOS part he had and he was looking 3 fortunes for it for a start and was really unhelpful when I asked legitiment questions so I got peaved off and left it.

I also recall this stuff is made to order I think he said. So he doesn't keep inventory generally.

 

[5thscaleracer]

I have worked with these guys in the past we were doing some performance mods for the 190E platform. He would sell my components in his neck of the woods or some in the USA.

Bottom line...
-Won't give credit where it's due.
-They have alot of ideas and concepts of "What is possible"
-Delivery and execution is not the best, if it's something they commissioned out for a customer like Ohlins TTX. Then the product quality is to Ohlins standards. But if they are making it from scratch the overall fit and quality is 90% ideal.

I don't think they make anything in house if it's a "Rennsport" product its farmed out to someone else. If it's a branded product then that manufacturer will "Private Label" for rennsport.

Horrible customer support from End user and Wholesaler experience.
No Support once they have your money then it's a fight to get something in return.

FWIW my experiences were from 7 years ago, but i have other 190E customers who are still waiting on their ITB setup which is going on 3 years now.

Rennsport can talk the talk but they simply do not deliver.

Don't buy into the Hype

Elbe out of Estonia has some goodies for the M119 same with Stern Garage.

What do you think about Garagistic's 190E stuff?

 

[5thscaleracer]

What do you think about Garagistic's 190E stuff?

I deal with Matt @ Garagistic (Owner), they sell some of my stuff and they make other things. Their focus is BMW but Matt is attempting to dip into the 190E market. Sadly the MB performance game is not the same as BMW, Audi, Porsche. MB performance is not sustainable as a business unless you overcharge. So MB platform for them will be small.

Garagistic makes everything in house, all of their components are tested by their staff or other race teams. Everything they make is 100% race. They focus on the true Grass Roots racer...

Equipment includes 4/5 Axis, Automated Turning stations, ability to make PU in a pressure chamber, 3D printing from small scale to large. They are full on production quality facility for any automotive parts. They also do Private Label CNC work for some other firms.

The beauty with Garagistic is they stick to a category and perfect it. So they are big on suspension modification, driving enhancements like their DSSR shifters. They are a company that will find a problem with a platform and perfect it for the racer.

Other items that they don't specialize in Garagistic will partner up with another company who is an expert in that department and "Co-Brand" the product.

But no issues with them at all good to deal with and they always help me out on my one off projects.

A very recent update… I contacted Rennsport again out of curiosity to ask what they had to offer for M113/K Singlemass flywheels and clutch kits etc… they told me it would be 8-16wks wait time!!?????

Meanwhile Kangaroos Team single mass kits which in my experience are exceptional quality, built in house, perform fantastic and have some of the best customer service get to me in Seattle from Bulgaria in 2 Days!!!
Needless to say, red C55 got a kit from Kangaroos team good for 700nm and fantastic price point imo.

As far as Garagistic goes, ditto to above, I’ve worked with them a handful of times now and have never been let down. They have some fantastic stuff they offer and hopefully will dip their toes further into the 201 and other Benz Chassis with time. BMW is king when it comes to aftermarket Euro though so I get it. I’ve been talking with Matt about partnering on my 190e build, hopefully it will all work out, they are the real deal.

The Kangaroos Team is also another top notch vendor their components are very good quality and it is indeed made in house.

 

[anderzen]

They are awesome, Petyo, of The Kangaroos Team, the one you will talk to in most cases is amazing with staying in touch and helping when anything pops up. More proof in the pudding about them.. I told Petyo I wanted to develop camber plates for the W203 C55, I sent him measurements and within 12 hours he sent me the 3D renders... 3 DAYS later they were on my door step and fit PERFECT! I am currently the test mule for their W203 Chassis mounted shifter for the red C55, direct bolt up to factory mounting points, otw here now and I can't wait!

That's likely because they have nothing, would need to start R&D from scratch, and need someone to send them a bunch of money along with a bag of wishes, hoping to receive a viable product (maybe) a year later.

 

[socal210]

I also recently had the displeasure of trying to work with Rennsport Factory as well. 100s of emails back and forth just for him to stop communications when it came time to deliver the product. Seems like most of the parts on the website are all theoretical and don't have real world installation with proof they actually work. Highly recommend avoiding them.

 

[RennsportFactory]

Tough Crowd.

When I started this company, the goal was to cater for a niche in our Mercedes and offer the custom parts no one else seemed to, this was knowing full well it wasn’t going to make me rich and likely be more work. I have no interest in importing Chinese or cheap parts, had no idea what would be popular and ultimately still don’t. Over the last 6 years I’ve managed to acquire what has essentially become a scrap yard of 12 cars and multiple engines and gearboxes used for testing and fitment checking which I’ve decided I’m long sick off and need to clear. So for the last year or 2, the goal has been endless designing and test fitting what is hopefully a modular range of parts for the older models and also other brands.

In turn social media and the website has been neglected, I understand it comes across we are only a design shop, that is not the case. There is a whole host of finished products that should have been added to both and hopefully should have finally got some help with this side of things.

As stated above the demand for these parts is low. From a business perspective, it doesn’t seem worth it to invest a large number in making kits that will sell 1 every few years. I initially used to take a hit on designing one off parts in the hope they’d sell in the future but it just isn’t viable for a lot of them. I’ve tried to gauge interest from the recent posts but ultimately it looks like time is much better spent on other brands. Which is why every party has been designed to be modular.

If you’re taking it on as a hobby, doing it for yourself in the hope they sell after, it is a bit different, but from a business perspective, the market doesn’t seem to be there to invest a huge amount of time and effort into things that don’t sell often.

The 119 ITBs shown are not our design originally, we found it and got it out there. The listing is 6 years old. A few have been sold over the decade this has been available and the only feedback I have is someone struggled to make decent extra hp on a stock engine. I have no details of the car, ECU or engine to comment, but given the chance I’d redesign it with longer M159 style extensions which will give a wider torque curve for more tame engines since it is rare for people to build M119s. I have equations near the right length but it would need development to get it 100% and cater for different specifications. M113 and M156 have been designed and test fitted. Unsure when they’ll get made at this point, it is in the queue.

Speaking of something I should have got listed a long time ago. Here is our W124 Ohlins kit. The gold needs polishing and I need to get a full picture with all the spring options, but this is what we recommend for the road.

The ITB's shown in theory could make quite a bit more peak HP, or generally increase power at high RPM... at the expense of low-end & midrange torque.

Note this post is from 2018 - they've had these "available" for 5+ years and not one person has before/after dyno results? Riiiiiight.

GSXR, have you ever worked with a dyno? Are you aware of how easy it easy to fudge numbers to suit what you need? Why is that the infallible source? Why is a good review from someone who probably doesn’t know what they are talking about a worthy advocate for a sale? That is how BC Racing are pumping out Macpherson struts with 2.1mm wall thickness with thread root weakness clamped right where the strut is seeing a bending moment. This would not pass any safety standard in any 1st world country. People seem to blindly believe a talking head video, you don’t need any qualifications to give advice on the internet and generally speaking what I’ve noticed is the ones that talk the most on these platforms seem to show the least amount of knowledge.

Cams are generally fitted with a range of other modifications, it is fairly rare to simply bolt in a set of cams and dyno before and after. Aside from that, what version and spec engine should be tested? Which spec cams? What about mapping? Are we comparing stock to stock or stock remapped with cams?

Demand is low for the majority of these parts and as we’ve all seen time and again over the years on forums like these, 100 people will say they’ll buy something then when it comes down to it, 1 or 2 actually do.

I can probably count the amount of M119 enquiries in 6 years on one hand, which is a shame but the numbers simply don’t add up for a heavy investment. Less so for the cams, but yes M119 cams are just regrinds like what has been available for years. Have they got any dyno info? We can machine them from billet also, costs around £4k. Can get that down with 5 or 10 of each, would likely take 4-6 months. Working on the assumption there was no interest, I haven’t got round to offering these anywhere.

I’d love to develop this platform, but I’m a small company, not a garage, we don’t do builds for others anymore and it’d have to come at a time when other parts with more interest aren’t the priority.

JC220, we don’t sell OEM parts and I don’t recall offering much out at all in recent times, but If you felt something was too expensive and were asking lots of questions whilst trying to haggle. There is a high probability I would not be massively pleasant. There is no American or Amazon style customer service here. I’m an engineer, not a salesman, I like to be blunt and will probably swear occasionally. Do let us know what part you are referring to though? I’d love to know what was considered “unpleasant”.

Hi JC. Thanks for the kind words.

I’m not sure how you can say you’ve had a poor experience 7 years ago since the company has only been going for 6. Nor do I recall selling you a single component. Please do clarify how you can say you’ve “worked” with us to be able to form these opinions? Because dealing with you is news to me.

Rather 2 faced compared to our interactions, shame you feel the need to fabricate this information.

I do remember refusing to stock your roll bars and buying an oil plate blank and front pulley from you, and if you noticed I didn’t come back for more. Reason being, the design and finish wasn’t the level of quality we like to offer. This is my first mention of it since. I still have those parts in a cupboard.

Please do clarify specifically what has been “90% ideal”? On one hand you say we don’t make anything, then on the other you say the parts we make are 90% ideal, a little contradictory don’t you think? It can’t be both.

Quite the range of spiteful things to say. You come across quite bitter about something. Sincerest apologies I refused to store and sell your parts, they just weren’t for me. I’m confident the various customers I spend hours on the phone to will say otherwise in regards to our support, but generally speaking we don’t get a huge amount of questions, feedback or problems after something is fitted.

There was a facebook post how Hendrick was no longer associated with his own company? Is that still the case? Seems like the whole world is struggling at the moment. Certainly been a challenge running a business with the current world changes.

How are your Quaife knock offs doing? People still waiting years for those? Happens.

I remember seeing you dishing out some really subpar advice regurgitated from a Taiwanese suspension manual that showed a complete lack of basic suspension understanding recently. I did my best to refrain from correcting you so you could maintain that self proclaimed “Expert” status.

We have taken too long with some parts recently, various reasons, in turn the supplier and parts list has been whittled down, everyone gets a larger estimate about lead times and we’re careful with what work is taken on now. There is only one person who has been waiting anywhere near that long, he’s been given an upgrade from single to twin plate clutch and was offered the old kit multiple times. Getting the 190e kit ready to a point I was happy with it, being able to cater for a large range of specifications was a challenge. Actually making it so the cost wasn’t £8k in low volumes has been even more so of a challenge. Most of the carbon parts are done, but I’ve had a machinist make a batch of parts, wrong, and in the time I sent them back and thought I was being patient with them, they’ve gone bust. Way of the world at the moment but just one of the setbacks I’ve been working through.

Hope your day improves.

A very recent update… I contacted Rennsport again out of curiosity to ask what they had to offer for M113/K Singlemass flywheels and clutch kits etc… they told me it would be 8-16wks wait time!!?????

Meanwhile Kangaroos Team single mass kits which in my experience are exceptional quality, built in house, perform fantastic and have some of the best customer service get to me in Seattle from Bulgaria in 2 Days!!!
Needless to say, red C55 got a kit from Kangaroos team good for 700nm and fantastic price point imo.

As far as Garagistic goes, ditto to above, I’ve worked with them a handful of times now and have never been let down. They have some fantastic stuff they offer and hopefully will dip their toes further into the 201 and other Benz Chassis with time. BMW is king when it comes to aftermarket Euro though so I get it.

I am currently the test mule for their W203 Chassis mounted shifter for the red C55, direct bolt up to factory mounting points, otw here now and I can't wait!

Anderzen, I don’t deal with people on Instagram or social media in general aside from initial enquiries. Main reason is it becomes difficult to follow, but also partly because I rarely go on there. So far, you’ve asked for various discounts in exchange for influencer style social media coverage. As explained, we don’t do this. If you see our parts on a car, the customer has chosen and bought them.

We didn’t respond about you being so proud of those top mounts because in our opinion they are dangerous and shouldn’t be on the market. If you’re happy testing parts like that from one size fits all sellers who lack engineering experience - on what for us is a $20k car, you’re a braver man then me.

I’ve bought parts from “kangaroos team”. The machining work was awful, the material looked like it was stored in a pond, it didn’t fit at all and I was told that apparently a tolerance of 1mm on bolt holes is to be expected, that’s tough shit and I should elongate. If you look closely at some of the details on the builds, they are not designs which would go through scrutineering in this country and I certainly would not want to share a track with them whatsoever. I’ve seen multiple complaints also, about the manifolds splitting, clutches not fitting and I can assure you the design and engineering is visibly sub par and sometimes obviously flawed on a lot of their components. Any trained eye can see this.

But people like cheap hey?

One concern is no mention of balancing details on the flywheels. Dynamic balancers are expensive machines, especially if you want to hold a good tolerance. Have they got one in house? Or do we just not talk about that and blindly recommend someone lacking in engineering experience putting out cheap parts because they’re fast? I do hope people don’t start to get engine issues.

We could easily sell a cheap kit for auto ring gears with off the shelf cover and lie about the torque rating, but as it stands a 240mm cerametallic on a stiff spring is one of the worst clutch experiences I’ve ever had. So we don’t sell those to people. If you want a race clutch, you get a race clutch to suit what you’re doing, not a road clutch bodged to hold more torque. If you want a dual purpose or high torque system for a road car, that is what you get. Something that doesn’t make you look forward to getting out of the car. Every order, we ask about the car, torque level, where and how it will be used to decide on what to offer.

The lead time is because every component is designed, machined, assembled and tested in the UK by multiple people earning a good wage. You asked for a high torque road 900NM road clutch. The cover quoted was for a twin 228mm race cover in billet alloy, modified with a curly tipped diaphragm to suit the OEM release bearing and extra springs to ensure a full release on the road. The cover, inter plates and flywheel need machining from scratch because a twin 228mm isn’t a usual choice and the setup height is specific to that kit. The Kevlar discs need bonding, setting and the flywheel needs every starter motor and timing tooth machined into the billet, this is then dynamically balanced. This isn’t something knocked out in a shed on the old bloc or imported from China in a few days.

If you can’t see or appreciate the differences or our attention to detail when making comparisons, there isn’t much we can do.

Here are the 500 and 1200NM twin plate kits that drives like a normal clutch on the road. Response is improved along with thermal capacity.



This is a kit for the 190e, designed to improve inertia whilst still driving well on the road.

Socal, who are you? What did you order? I don’t have 100s of emails from anyone in my inbox. If I apparently stopped communicating, why did you not try another method? I spend most of my day sat in this office seat answering emails, sometimes I need a break. Or a few days off, or emails go to junk, or like over last Christmas last year I got ill and needed time to recover. Shit happens, unfortunately and if it does there is no one else to answer emails. Regardless I highly doubt what you are saying is true. Ultimately, I don’t go chasing customers for reviews, fitment pictures or anything after a sale in fact.

 

[Draginev]

This is quite embarrassing. I hope that this will resolve with mutual respect and clear the air once and for all. We are all adults and must solve this in a matured manner.

GSXR, have you ever worked with a dyno?

Why yes, I have.

Are you aware of how easy it easy to fudge numbers to suit what you need?

Sure, if one wants to build a business on fudged numbers, they can do that - but likely won't be a commercial success.

Cams are generally fitted with a range of other modifications, it is fairly rare to simply bolt in a set of cams and dyno before and after. Aside from that, what version and spec engine should be tested? Which spec cams? What about mapping? Are we comparing stock to stock or stock remapped with cams?

Either do market analysis and figure out what modifications most people would be willing to add along with cams, or provide a complete kit with instructions on how to replicate the power gains from your dyno testing. You are the manufacturer / tuner, people are paying YOU to figure this out, so they don't have to. I don't want experimental components that haven't been tested or proven. Maybe other people do?

Demand is low for the majority of these parts and as we’ve all seen time and again over the years on forums like these, 100 people will say they’ll buy something then when it comes down to it, 1 or 2 actually do.

100% accurate statement. ^^^

I can probably count the amount of M119 enquiries in 6 years on one hand, which is a shame but the numbers simply don’t add up for a heavy investment. Less so for the cams, but yes M119 cams are just regrinds like what has been available for years. Have they got any dyno info? We can machine them from billet also, costs around £4k.

Chicken & egg here. I'm not paying €/$/£2k for regrinds, nor 4k for billets, without dyno graphs showing what the gains are across the powerband.

Long time no see you! and glad to hear your development is continuing!

I am also kind of monomania, and M119 is just my hobby and leisure. not so much serious like racing team or business.

I might feel that major part of guys in these field is not so serious or relatively concerning about how to squeeze budget,
return on investment, cost performance or Time performance than you image that based on our racing field.

as I told before,
I am also billeting Cr-Mo gun drilled Cam shafts for M119 and have already done own profile/maximum lift/ degree with Non HLA.
And its special over sized Valve, tappet, wrapping, DLC coating, Springs, Titanium retainer, cotter, valve guide and rings from racing field.

These are too expensive to sale for Clever consumer.


Any way I am also doing, That's for fun.

Anderzen, I don’t deal with people on Instagram or social media in general aside from initial enquiries. Main reason is it becomes difficult to follow, but also partly because I rarely go on there. So far, you’ve asked for various discounts in exchange for influencer style social media coverage. As explained, we don’t do this. If you see our parts on a car, the customer has chosen and bought them.

We didn’t respond about you being so proud of those top mounts because in our opinion they are dangerous and shouldn’t be on the market. If you’re happy testing parts like that from one size fits all sellers who lack engineering experience - on what for us is a $20k car, you’re a braver man then me.

I’ve bought parts from “kangaroos team”. The machining work was awful, the material looked like it was stored in a pond, it didn’t fit at all and I was told that apparently a tolerance of 1mm on bolt holes is to be expected, that’s tough shit and I should elongate. If you look closely at some of the details on the builds, they are not designs which would go through scrutineering in this country and I certainly would not want to share a track with them whatsoever. I’ve seen multiple complaints also, about the manifolds splitting, clutches not fitting and I can assure you the design and engineering is visibly sub par and sometimes obviously flawed on a lot of their components. Any trained eye can see this.

But people like cheap hey?

One concern is no mention of balancing details on the flywheels. Dynamic balancers are expensive machines, especially if you want to hold a good tolerance. Have they got one in house? Or do we just not talk about that and blindly recommend someone lacking in engineering experience putting out cheap parts because they’re fast? I do hope people don’t start to get engine issues.

We could easily sell a cheap kit for auto ring gears with off the shelf cover and lie about the torque rating, but as it stands a 240mm cerametallic on a stiff spring is one of the worst clutch experiences I’ve ever had. So we don’t sell those to people. If you want a race clutch, you get a race clutch to suit what you’re doing, not a road clutch bodged to hold more torque. If you want a dual purpose or high torque system for a road car, that is what you get. Something that doesn’t make you look forward to getting out of the car. Every order, we ask about the car, torque level, where and how it will be used to decide on what to offer.

The lead time is because every component is designed, machined, assembled and tested in the UK by multiple people earning a good wage. You asked for a high torque road 900NM road clutch. The cover quoted was for a twin 228mm race cover in billet alloy, modified with a curly tipped diaphragm to suit the OEM release bearing and extra springs to ensure a full release on the road. The cover, inter plates and flywheel need machining from scratch because a twin 228mm isn’t a usual choice and the setup height is specific to that kit. The Kevlar discs need bonding, setting and the flywheel needs every starter motor and timing tooth machined into the billet, this is then dynamically balanced. This isn’t something knocked out in a shed on the old bloc or imported from China in a few days.

If you can’t see or appreciate the differences or our attention to detail when making comparisons, there isn’t much we can do.

Here are the 500 and 1200NM twin plate kits that drives like a normal clutch on the road. Response is improved along with thermal capacity.

This is a kit for the 190e, designed to improve inertia whilst still driving well on the road.

I'm not going to get into telling you how to run your business or choose to say anything negative or argumentative. I was simply laying things out as I've experienced with transparency. This is an internet forum after all. My apologies if anything said caused harm.

I reach out to companies like yours who I see have put in a lot of time and effort into products like what you offer, to hopefully help aid an increase in visibility/sales for your brand and products. For our niche community, every person counts and in my experience, no matter how long someone has been in this Benz world, sometimes they just don't see, don't hear or don't believe in products without it being point blank with data to back performance/results. And even then, there will be questions, a need for further proof etc. I am not just an influencer or person who provides coverage for your products/brand... I am involved in the design, revision, install, testing, feedback AND using my skills as a designer/videographer to take the time to document and edit it all into multiple shared formats and assets.
My builds and videos and more importantly testing/feedback help provide that information to consumers and to the businesses and individuals I work with in a easy to follow form.
So yes, I am asking for a discount or parts sponsorship in most cases because of the value I offer, and because for every company I have worked with there has been a positive return on investment on their behalf. I don't need to spill out numbers, but if a company offers me one part sponsored or discounted and in return I bring them 30 customers, the math is pretty simple to figure out. I helped them, they helped me continue this passion of mine, everyone wins. Simple. I am contacted daily by companies with a desire for me to parade lackluster products I have no care for sharing. I reach out to companies I am interested in and that I believe my Channel's community will be interested in. With the pure and simple goals to help, share and progress, that's it.

Your opinions on The Kangaroos Team are yours. I have had nothing but positive experiences with them from a product and quality standpoint, and from a communication and collaboration standpoint. More importantly, their pieces have all stood up to real world use in my vehicles, not one issue in years of use. So while they may not reach your level of desired detail, they work, are extremely time efficient and provide a tremendous value at their cost for those interested in modifying their cars with they have available. They also are a Championship Winning Drift Team that run a huge catalogue of their own parts, I don't think they could do that with out a bit of engineering, experience and R&D...

In the end, may you be like Bruce Lee and take what is useful, leave what is not. Running a business is not easy and feedback like this may be hard to hear, but maybe their is some value within for you to take forward. Wish you good luck in your continued endeavors and the door is open should there ever be a time to work together in the future. Cheers.

*Edit: In addition, one last thing which I think is really important to say.. In this Benz game and World of people who take on the challenge of running a business producing parts for the likes of us, I think we often assume there is a big Team involved or lots of money involved, and simply more times than not, it's just not the case. These are individuals, humans with real lives and real things going on. So kudos to you and others for carving out a niche within a difficult path. I know how difficult that is and is one of the reasons why I am so passionate about trying to move the ball along and helping companies like yours succeed, so although it may look like I am just asking for hand outs or favors, if what I do can offer even a temporary boost to that quest, I see it as helping the greater good for these cars which I enjoy and love. As silly as that may sound.
