Default Track wheel setup

I would like to know if a 10”x18” wheel with 43 offset would not rub anywhere using 275/35x18 R compound track tire. I have mounted this wheel without tire to see if it clears the AP racing brakes and suspension. It appears the only close place is at the fender liner behind the oil cooler area when the wheel is turned to full lock inward.
Thanks

That is a 19 x10 43 offset c7z wheel with stock 285 cup tires, rubbed a bit in the rear, front was good.I’m currently running a 18 x9.5 in the front with a 275 on a C6z wheel 40 offset, no rub. So I’m guessing it depends on the tire height. The 275 on the 18 x10 probably won’t rub because of the tire being stretched.

Thanks, that helps a lot. I had two extra 10” wheels from my M4 and now going to buy two more 11x19 inch BMW wheels from Apex to match the fronts. Concentric rings make that possible.

We are currently running a 18x10 Forgeline GS1R on the front of our Track C8.

Tire is currently a Nankang CR-S 295 in the front and plan to go wider.

Is that John’s car? I think he was running ET39 offset. Is that still the offset?
Thanks to all for the responses.

yes thats my car... my effective offsets on my car are: ET39f and ET42r

Most every tire i have run up front is a 30 series, be it 275/285 or a 295. I fear a 35 would be a bit too tall and would rub though i am not certain. The room at the rear of the front wheel is quite narrow.
