You could maybe get a 235 in there, but a higher offset like ET37-40 would be preferred in which you'd be able to fit that 235 or 245 you desire.
Awesome, good to know!

So for the bumper mount bolt would a bumper quick release dissolve the need for that? Haven't started crawling under my car yet, still researching at the moment.

Also looking into e9X m3 complete rear end to solve the LSD problem. Plus you gain 20mm of narrower track total width. If I've researched correctly....

Struggling finding a wheel I like for the size needed on our cars. AHHHH

Front: (18.8.5) (ET45)
Spacer: (3mm or 'none')

Rear: (18x8.5) (ET45)
Spacer: (5mm or 'none')

Tires:
Front (Pilot Sport 4s) (235/40ZR18)
Rear (Same)

Suspension/Fender Mods/Camber: None Needed but since have done KW Variant 1 all around with solid upper and lower mounts in the rear.

Apex Arc 8 in 18X8.5 ET45 on a Square 245/35-18 Continental Extreme Contact Sport tire.

Car is a 128I M Sport. No rubbing issues whatsoever on the stock suspension and they fill up the area nicely. Crappy Pic...but the back actually sits the same height as the front, the shadow just makes it look different.

I’d like 245s in the front but I feel like that’s a going to be 3 degrees plus of camber?? Would like to keep it under 2. Currently on kw v2 but I don’t think there will be any inner clearance issues.

Lastly anyone know if I could run a square 255/35 if I bought the n5tunner front fenders, says it gives 15mm of extra clearance. But I don’t believe you get that much if you are full lock??

Will be autocrossing the car!

Any input or confirmation is much appreciated! Thanks!
If you are going to be autocrossing the car, you absolutely want the max front camber you can get. No ifs, ands, or buts about it. At -2.9 (the max I could get with my camber plates), the car was pretty good, but when I added the offset bushings to get to -3.6, it was much faster.

To run the 8.5 +35 up front, you are going to need camber plates and probably at least -2.5, potentially more, to make it fit.

The N5tuner fenders are unnecessary for those tires - just make them fit stock. They will render you illegal for a bunch of autocross classes that the car is otherwise really well suited to.
