Help ! Offset and tire question for my M4

Hey All,

New to the scene here.

I wanted your help as I got some new wheels for my f82 m4.

20x9 et 25
20x10.5 et 26.


Will they fit on my m4? It is currently lowered on H&R SS and I also have spacers all around on my stocks to give it a flush look

The wheels are originally off a e92 m3. Will they fit on m4 f82? Also what tires do I need? 255/30 & 285/30?

Thanks,

The front is fine (may need a spacer depending on what look you prefer) but the rear is pretty aggressive. Typically, a rear 10.5Ē wheel has an offset between 33-35 mm.

Awesome. Thanks guys. I saw some on here with similar setup. As long as I can get away with no rubbing ill be happy. Yes fronts will probably need spacers.

How much negative camber did/do you have to run? Iím currently running a 19x11et40 with 305/30 PS4S and I couldnít go anymore aggressive without rubbing. Iím running -1.8 deg of camber on the rear.

A 285 will be slightly stretched on an 11Ē wide wheel but youíre also running a 15 mm more aggressive offset. Volks with 11et34 can barely run a 285. Do you have pics of your rear setup?

I have 10.5 +30 in the rear on my M3 with Continental ECS 285 and Macht Schnell springs. one finger gap between entire tire sidewall and inner fender. Any lower or wider and I'd be riding the fender walls. Not sure if M4 has any more clearance, but H&R Super Sports are really pushing it.

Seems your good on your fitment numbers.


Currently grabbed a deal on a set.

20x9.5 + 15
20x10.5 + 15

Able to pull this off in the rear with stock camber adjustment and a 265/30/20??

Fronts I may go with a 245/30/20
