Are they ok for Z4 M?

Thanks!

You should post in the Wheels/Tires forum... I am sure it would get more replies... and you would also be following forum guidelines

If my calculations are correct the front wheels are within 1mm of the OEM wheels' fitment while the rear wheels are less than 3mm from the OEM wheels' fitment so you should be ok.

OEM: Front: 8*25.4/2 + 42 = 143,6mm
Rear: 9*25.4/2 + 30 = 144,3mm

Your wheels: Front: 8.5*25.4/2 + 35 = 143,0mm
Rear: 10*25.4/2 + 20 = 147mm

Cheers.

Sorry that calc doesn't work......
Use this calculator to estimate effects of offsets & wheel size.

10" ET20 are VERY aggressive & will likely rub
A 10" et20 wheel will EXTEND out an extra 34mm!!!

It would extend the rears 23mm not 34mm. Not sure where that calculation came from. the stock Z4M's rear wheel is 9 inches wide with a 30mm Offset. The fronts would be fine they would extend out 13mm. But 23mm further out in the rear is too much. The wheel will sit further out then the body.
