ughhhh these rims are killllling me, it hurts when u find something in ur price range and something that you like but you just dont kno if they fit or not.....
ZEE4KEVIN, here is the problem you are going to run into...
All Z4's with the exception of the "M" use a combination of rim and tire sizes that equal about 25" in diameter...
245/35/20 will equal a diameter of 26.8" and that is a problem... :thumbsdown:
275/30/20 will equal a diameter of 26.5" and that is a problem as well... :thumbsdown:
Finding a tires combination that will fit both the front and rear rims is going to be a problem...
The 20" rims that I have seen that will fit a Z4 are all 20 X 8.5 running 225/30/20 tires at all 4 corners.
Like many others here I don't care for the 20" rims but if you like them go for it... Just don't want to see you get something that won't actually work...
