7.5x17 Evo wheels + "big" brakes - where do they interfere?

[E_S]

Hey,
I have a set of 7.5x17 Evo 2 wheels (P/N 170 401 17 02) laying around. I understand they won't fit most 320mm and up brakes. Where do they interfere? Is it the spokes (can be solved with a spacer within reasonable limits) or the "wheel itself" that will be the point of interference? At the moment I don't have any brake calipers at all on my car, so I can't try it out myself..

Hi mate

These wheels has ET37 so the difference is only 3mm from the EVO II for the 036. I'm not sure they will interfere, but if so I guess the spokes would hit the caliper. Should be solved easily with a tiny spacer. This is probably the Ceginus wheels?

Yeah, that's right! I have them because they fit better on my car with the standard (non-500) wheel arches. I do have the option code for body modifications to fit wider wheels, so a spacer shouldn't be an issue. If I could fit them using a spacer, that would be great. I'll give it a try

That sounds fine.

I'm sure I've seen those wheels on a 036 at some point, but I don't have any fitment information.

I had these 7.5x17 Evo wheels on my 500E when my I bought it, but the car did not have the larger 320mm front discs. It also had 15mm spacers on the front, and 20mm on the rear, but I'm afraid I can't tell you whether this was because of a clearance issue or not. I discarded the wheels and spacers for a "proper" set of 8.25x17 Evos, plus also some original 16" wheels as second option.

The 7.5x17 EVO wheels will not clear factory FRONT brakes larger than 294/295mm diameter.

The interference is between the spoke and caliper face. You need 15-20mm spacers to make the wheel clear the caliper. If you use a thick enough spacer, they will clear the 300, 320, and 334mm front calipers.

There are no clearance problems with rear calipers up to 300x22mm.

Dave, I don't believe you need more than about 10 mm spacers to fit 7.5 Evo's over 300+mm brakes. It's been years since I tried (on my old 16V with alloy Brembos) but as I recall, even a 5mm spacer would provide enough clearance. My memory could be off, but that's what I recall.

Glen, it will depend on the exact caliper you are trying to clear. I did not have spacers available to experiment with, but my notes from June 2012 read:

"Based on my measurements the 7.5" Evo wheels would likely need a 10mm spacer to clear 320mm calipers, a 15mm spacer to clear the 334mm Brembos, and possibly as much as 20mm to clear the 300mm calipers (either Ate or Brembo)."

I could have been off by a few mm for any of the above, so take the numbers with a grain of salt.
