What's the largest wheel for Z4

[champn203]

Can anyone tell me the largest wheel size that will fit on a Z4 (non-M) without modifying the wheel well or fenders? I am hoping to use a staggered fitment of 19 X 8.5 and 19 X 9.5. Thanks

I'm running M3 Offset 19x8.5 & 19x9.5 slammed with KW Variente 2.

Rubs in the front a little but its fine in the rear. It lines up perfectly with the fenders.

Got pictures of that setup?
