Offsets and Sizing

M5KEITH · 01-22-2023, 11:58 AM

Hello,

Wheel gurus…. Will these wheels work and looking to have them be flush.

Wheel Specs:
Brand new set of 4 Rohana RFX17 ROTARY FORGED Wheels / Rims
WHEEL SIZE: 20
WHEEL WIDTH: 10.0 FRONT AND 11.0 REAR
WHEEL OFFSETS: 22 FRONT AND 32 REAR
BOLT PATTERN: 5 X 112
FINISH: GLOSS BRONZE FINISH

285/35/20 Front
295/35/20 Rear

Car is stock height non comp but might also look to go with M550I springs.

Compared to the OEM wheels, the front will stick out 12mm and the rear will stick out 2mm.

Thank you this was what I was looking for.

So should I just go w/stock tire sizes then?

If I go with 285 on the front wheel might be too far poking out fender?

Many put 15 mm spacers on their stock front wheels. I think you will end up ok factoring in the decreased wheel offset pushing the wheel out by 6 mm plus half of the 12.7mm increased wheel width (the half of the 10mm increased tire width should not add to that since it is sitting on top of the increased wheel width). You won’t want a spacer.

I plan to run that size up front on my similar spec Titan7 TS5. I have H&R M5 springs but people have run this same combination with the 550xi springs.

The front is ok, rear I would throw on 8mm spacers

Below is 21x10 ET22 front and 21x11 ET24 rear to give you an idea on flushness, moderate drop
285/30/21 and 295/30/21

I personally prefer the rear to be slightly more flushed than front for a perfect stance
