Hello, looking for wheels size and offset ideas. Please post your track wheels setup with offset here. Thanks.

Still running stock at the track but am also interested in what others are running. Thinking about a square et 35 19x9.5 with a 5 mm spacer in front. I did a test fitment with 265/30s and this will work.

Thanks, but now I am a little puzzled with the spacer size. You really meant 15mm, not 5mm?

Sorry for all the questions.

15mm is likely correct.

We're running 18x10 et35 with 275/35/18 and using a 12mm spacer up front to clear the strut.

I was thinking that if the wheel is 9.5 inch (i.e 12mm narrower), one can use a slightly smaller spacer while keeping same distance strut side. However, this would mean the wheel would be slightly in from the fender.

I am a little averse to tracking with larger spacers, as I had a mishap once, (which could have been a fluke) So trying to limit my spacers to 5mm.

Thanks

No I meant 15mm. The car has Clubsports installed and needs the inner clearance. The wheels sit perfectly flush at -1.5 camber up front. The spacers are not ideal, but it's what's necessary on this car to keep a square setup and the ability to rotate the tires. Custom wheels can fix that, but the ability to rotate is nice. I just make sure to check the torque on the wheel studs when the wheels are off and the lug nuts before each session.

Aaah! That explains it! Thanks

Does the tire stick out past the fender with this setup? I bolted a 18x10 ET25 with 285/30/18 Hoosier to my M2 and it stuck out a lot.

The Hoosier will be a bit beefier than our street tire, but no it sits inside of the fender with -2.5* camber.

Ah ok the camber must be the difference also the hoosier was a 285. I may try and stuff some 275's on my 18x10 ET25 EC7's once I can get -3 camber.

The rear has more clearance issues than the front on the M2, correct?

No, the rear could probably fit a 295 or even a 305 if you built a wheel to extend inside another inch or so.

We chose to run an et35 (which limits us to a 275 in the rear) so that we could cut all 4 wheels with the same offset and simply run a spacer up front to make it work which would allow us to rotate front and rear wheels without any issues. If you cut a staggered set you could get away with a 275/295 stagger with an 10.5-11" rear wheel.

What rear wheel offset would you use if you went 10-11 inch rear wheel, +25?

How big of a spacer do you use on the front with the +35 wheel? I may be wrong but it did not seem like I had a lot of strut clearance at full lock with a 18x10 +25 EC7. The tire was a 285. I'm on stock alignment

We run a 12mm on the front (effective ET of +23mm) which would give us about 2mm more clearance than your +25mm.

I haven't measured the inside clearance on the rear exactly but if I ran a 10.5 or 11 the offset would have to be higher, closer to +47 or so with the 11" wheel.
