Offset/spacer question

Gladius · 05-08-2009, 03:51 PM

I have some CSL reps off my E46 M3 and was thinking about using these as track wheels on the E90.

Stock sizes:
F 8.5 ET29
R 9.5 ET23

CSL rep sizes:
F 8.5 ET40
R 9.5 ET22

So, all other things being equal, to get these to be the same as the stock wheels, I'd need 11mm spacers in the front, is that correct? The rears seem close enough to work.

I know these aren't the most desireable track wheels (heavy, and not a square setup) but other things being equal, this should work?

Offsets will work fine without a spacer.

You are correct, and 11mm spacer will put the fronts right at stock. Without it, they will be sucked in more.
