Hello! Just traded my 2003 e39 M5 in on a 2006 E61 530xi Touring. Anyway, I still have my knockoff 18" wheels with Blizzaks. These are the wheels:

So I think they are 18"x8" 5x120 "13SM". I'm guessing this is a 13mm offset.

I've read that the offset of the E39 wheels didn't leave enough room to clear the brakes of the e60/61, but these are 18" wheels not 17". So I'm not sure what this all means. Someone also mentioned a spacer would be needed...how thick and where do you get these?

Any help is appreciated.

Thanks!
