Help 255 apex wheel fitment
Looking to to run 18x8.5 et35 apex wheels on my 2016 m235i. Currently lowered on h&r springs. Will I be able to fit a 255 square setup if I do vorshlag camber plates? (I've heard I need around -3 degrees of camber in the front). Is -3 degrees achievable with h&r springs and vorshlag plates?

255 is absolutely doable with camber plates. I'm running 255 squared for both my track and street setup with a combination of spacers and the Vorshlag camber plates and Dinan Lowering Springs, which I think lowers the front by 0.5" and rear by 1". My camber currently is -2.4 Front, -2.1 Rear
Track setup: -Apex EC-7R 17x9 ET42 wrapped in 255/40r17 (Nitto NT01) squared. -Spacers: 10mm F, 5mm R *Used to run 12mm F but there were major rubbing on the outside front fender area on hard corners. Switched to 10mm and all is well. Planning to bump up the camber to 3 deg for next track season* Street setup: -Apex Arc-8 18x8.5et45 wrapped in 255/35-18 (the et 35,38 is a much better option and more popular. I just went with 45 because that's all they had at the time. would go 38 or 35 if I could change) -Spacers: 15mm F, 5mm R *Rubbing is happening somewhere inside the wheel well on bumps. Never had this issue when I did 245 squared w/ Michelin PSS. Currently the 255s are Falken Azenis FK150. I measured and the actual width is almost 270. They run very large for some reason. Any other 255 probably wouldn't rub at all.* |

If you want to get into the 3 deg range, you're going to probably need a few more modifications. A popular one is the F8X M3/M4 LCA & TS upgrade, which I plan to do soon. Much material about that can be found on both 2 series and 3 series forums. FYI, getting into the 3 deg range will seriously eat up your tires if you're going to do mostly street driving. I would recommend like 2.2~2.3 max for everyday driving, even then you may see uneven wear pretty quickly. |

I've got 255 width tires, slight fender roll in the front (just the lip), and Swift Spec-R springs with Vorahlag camber plates at about 2.3-deg for street driving. They can go up to max 2.6-deg (ish) when I move the bolts to the end of the slot for track use. Do yours go all the way to 3.0-deg? Do you have F8X lower control arms to get the extra half a degree?
Track: 255/40/17 RE71Rs on 17x9et42 w/ 5mm front spacer, 2.6-deg camber Street: 225/35/18 Yoko Apex's on 18x9et45 w/12mm front spacer, 2.3-deg camber

https://support.apexraceparts.com/hc...-Fitment-Guide It shows that 18x8.5 et45 will require "5mm front spacers and at least 1.5 degrees of negative camber" to use 245/35-18 squared. This is actually the setup I had on my Arc-8s some time ago when I was running Michelin PSS. |
