Winter wheel size- will it work

PhYrE · 11-04-2010, 08:37 PM

2008 E92 M3 Coupe (Eibach springs)

It appears stock winter setup is 18x8 wheels with 235/40's and a ET20 offset.

Considering a set of 18x8.5 ET38 with 235/40 front and 255/40 rear rubber. Staggered.

How bad is this offset at the end of the day, primarily looking at- (1) will it rub anywhere and (2) how quickly will it shoot the bearings and (3) can it be easily fixed by spacers?

Ideas? Any help is appreciated.

I used to run that set-up. I ran a 12mm spacer in the rear. It worked out well. The dealer would install the spacers, but you will have to supply them.
