With an 9" wide rims, you'd need something with an offset of ET 42, and even then there's a great chance that the inner part of the wheels would rub against the front struts housings.

I had 19x9.5 ET42 (rear rims) SSR GT3's on my '04 Z4 3.0i lowered on H&R springs and it seemed to be another 7~8 mm before the tire would rub the edge of the rear fenders. With an 19x10 rim, you'd need something closer to ET50 than ET42, in which case, again, you risk having the inner wheels rub again the shocks.

My recommendations would be to go with 8.5" front rims and 9.5" rear rims at the widest.
Sorry to bring up an old thread but I also have H&R springs on my Z4 with 19x8.5 et 35 in the fronts and I am rubbing whenever i hit a dip or bump (even small ones) and also on hard cornering. I have 235/35/19 tires. What should I do to fix this? Remove the fender liners? Change camber settings? There is not even one finger gap between the tire and the fender. I'm just afraid that if I hit a big bump the tires would hit the fenders and mess the car up.
