Ideal offset for the Z4?

The ideal fit is 19x8,5 et 35 front
19x9,5 et 35 rear

et of 43 will place the outer edge of the wheel more to the inside.

Rubbing can occur on the inside, or outside I cannot address you question directly. If you did et 43 with a 9.5 your going inward.

Assume your going with the same tire and switching from a 19 x 9 with et of 35 to a 19 x 9.5 with et 43 you get 14mm LESS clearance on the strut side, and the outside edge of the wheel will RETRACT 2mm

There is a good tool for this on E90POST.com 3 series Forum, Wheel and Tire sub forum. Note the offsets stated there are E90/E92 not E89 Z4 but the directions are the same.

Good luck

Thanks a lot!

I guess 9.5 with +34 offset is the way to go!

Thanks!
