Looking for a little spacer help. I have a 2007 335 e90 with the sport package. I am running stock wheels and tires. Type 162 wheels (Front: 18x8 ET34 225/40 R18) (Rear: 18x8.5 ET37 255/35 R18).

I was wondering if anyone with this setup is running spacers. I was thinking about 10mm up front and 15mm in the rear. I have heard you can run 15 and 20. I am not interested in rolling my fenders BTW.

thanks

*edit: just noticed that your front offsets are 34, so actually i think your right with a 10mm

for the front you can go with a 12mm

Cool. Thanks. Just curious how can you tell what size spacer I need from the offset?

Offset - spacer thickness = new offset.
So ET34-12mm spacer gives a new offset of ET22.

Got it. But what does that have to do with choosing a spacer size?

B/C spacer size comes in 5mm,10mm,15mm, etc...so you have to know what spacer size you need to buy
