Z4 3.0si max width

dadoke · 06-24-2009, 03:00 PM

Hey all,

Been looking on the net for the last couple of days but can't find the answers i am looking for ... so here my question.
I am planning for new wheels on my 07 Z4 3.0si, but i was wonder if 9x19 or even 9.5x19 in the rear would fit without rubbing?
On the M-version they do fit, anyone have tried them on a non M?

grtz

I have 8.5x18 front with a 40 offset and 9.5x18 rear with a 43 offset. No rub problems at all with the 225/40 and 255/35 oe tire sizes.

Width, offset, and tire size are all factors you need to consider. Also, some combinations will work on a stock height car and will rub on a car that's been lowered. As far as the difference between 18/19 inch wheels, the area of concern is the diameter of the tire.

Any specifics on what you were considering?

Acceptable wheel width is 7.5-9.0 inch for 225/40/18 per mfg spec. Undecided if going wider.
