Typically for a direct fit, we recommend the following fitment for your Z4M:
18" Staggered:
F: 18x8.5" ET38 (Profile 1) - 235/40-18
R: 18x9.5 et22 (Profile 3) - 265/35-18 or 275/35-18
For customers wanting to run a concave wheel up front, then we recommend the following fitment:
F: 18x9" ET30 - 235/40-18
R: 18x9.5" ET22 - 265/35-18 or 275/35-18
The front will be close to the outer fenders on the Z4M, but it may work with 235/40-18 tires. It would require around -1.8 degrees of camber or more up front.
