Fitting 18' 9.5 rims of 15 offset

Trying to fit 18' 9.5 rims on the front of my 335i coupe. The offset is 15. Would that rub my springs or anything inside?

Nah, but that'll be poking out pretty far. Hit a bump with the wheel turned and you'll end up with a cracked fender. I recommend increasing negative camber to fit them, fronts don't have much camber adjustability so you'll need aftermarket parts such as camber plates.

15 offset on the back too would I roll back fender out?
Going to buy front camber plates seems fairly easy to install just would need an Alignment

Back is aggressive, I ran 18x9.5et22 with 255/35/18 MPSS, I needed rolled fenders and -3* camber to stop the rubbing.

What suspension do you have?

What tires are you planning to use with these? As mentioned, 18x9.5" ET15 is quite aggressive and will stick out beyond the fender. Negative camber can help, but without widened fenders the wheel will still come out past the fender.

For a 9.5" wide wheel, you want an offset of around 35 in the rear and 25-30 up front with negative camber.

Our fitment guide lists what offsets are recommended and what mods (if any) are required to make these sizes work: https://support.apexraceparts.com/hc...-Fitment-Guide

I have the rims got them on the low but where bigger then I was told. Have them on now but getting way to much rubbing. Was thinking of just rolling fender but sounds like I'll need to install camber adjustments on the back to. Got stock suspension on it

Rear camber is adjustable up to about -3* so your alignment shop shouldn't have a problem with it if you ask

The stock rear can be adjusted-3* with adding any aftermarket parts?

Just don't want to hit my strut bar or anything. +15 might be to much for me. Don't want to much of a cambered look either. Idk how it would look like. Might have to take them off n sell them I hope.
