WANTED WTB: Rials ARC M800 (18x8.0 ET35)

[BigWhimsy]

Hi all,

On the hunt for a set (4) of Rials ARC M800 (18”).

Any leads?

 

[Jlaa]

Just offering you another way to achieve what you want .....

The ARC M800s are heavy and have suboptimal wheel width / offset for the E500E. As well, they are cast.
You could commission a set of forged 18" replicas of the 8-Loch wheel from these guys for quite reasonable pricing: Bespoke Design - Custom Forged Wheels

Note as of today's date, CAD 1400 = USD 1018 ... so 4K USD for a set of NEW forged 18" 8-Loch replicas, while not inexpensive, would only be about 2x the cost of used, cast ARC M800s....

 

[BigWhimsy]

Thank you Jlaa! Great find.

Any experience with these guys?

@Ricardo put Augment forged 17” replicas of the classic Porsche 16” D90 wheel on his 964 and was considering getting Augment to do an 18” forged replica of the MB 16” 8 Loch wheel … but then he sold his E500 to @Teddy_West, so now either you or Teddy has to commission Augment to do so!

Here is a non-refurbished set in Germany, but only pick up and shipping may be a killing factor. However, they seems to be in good condition.

Ooof. $1900 USD plus freight to USA, plus (probably) straightening and refinishing... pushing ~$3k all in before tyres. And you still gotta deal with spacers, if you want the wheels anywhere near the fender lips.

That's a good case for brand-new forged custom wheels at ~$4k in the proper offsets & widths.

I still have plans of commissioning a set of them in the future. I must wait until some work is complete and I've sold some cars.

Any idea about specifications for the appropriate custom commission job? Re: spacing, etc etc

Offset (backspacing) will depend on your desired wheel widths. So to start, you'd need to figure out what widths you want, and if you plan on a square or staggered setup.

What I have had in mind is 8.5 et 26 and 9/or 9.5 et 25 - 30 with a flat face in front and a small lip on the rears. I will need a rendering as to how the factory design will look with this lip. If others want a square setup the fabricators would already have the 8.5 specs, and we would ask for a quantity deal.

Drew, if you’re going through that whole effort then you might as well go the whole nine yards and get them made out of magnesium

 

[sheward]

Love that idea! The imagined cost makes my cranium hurt.

One and a half years ago they quoted me $1,800 Canadian per wheel

I wouldn't be opposed to working out a group-buy on these. Let me know your thoughts. I'm likely partial to a square setup

 

[BigWhimsy]

Curious if anyone has insights or recommendations into proper widths if doing a custom job?

I'm now considering doing a custom job with Augment and would appreciate any insight.

This depends on the desired appearance / performance.

First question - square set, or staggered? If square, you're probably looking at 8.5" wide with ET's in the 25-30 ballpark. With staggered, you can go at least 10.0 in the rear.

Second question, what size tires are planned / desired? Some sizes are oddball and hard to find in mainstream tire brands/models (say, Pilot PS4 or similar). Related question, do you love or hate the "stretched" tire look? Because you can get a wide wheel with a skinny tire, however this would limit the market/demand, as some people aren't into stretch (myself included).

Note that offsets become critical as the wheel width increase. I.e., with an 8.0" wheel, there's a pretty wide range of offsets that will work, although appearance will vary. With (for example) a 10" wheel, the acceptable offset is very limited where clearance won't be an issue.

I am open to working with others on this project. I am stuck on the staggard fitment however that does not preclude sharing the front specifications. An 8.5 front rim is arguably the best choice for a square or staggard fitment. 245/40/18 tire is the logical choice for that rim size and is one of the most popular sizes with many choices.

My time frame on this is realistically mid 2025.
