Maximal offset for wheels on E89 23i

[eristoff]

Hi Guys,

I would like to know if it's possible to fit wheels with:

8,5J ET 20 in front
9.5J ET 22 on rear

on Z4 23i with M pack (m suspension) without rubbing ? and what is the max we can set ?

Thank you

PS: sorry if is not the good threat

Hi,
here is an overview, what is possible

of course, in german

To make it short: on the rear axis your 9.5J ET 22 is absolutely impossible, no way without additional work.
Series is 9J ET 40, and discs with 10 or 12 mm are possible, resulting in ET 28 at 9".
With 9.5J ET 22 you will be about 12 mm wider.
