Thank you for posting fitment pics. This is the first Z4 M we've seen a full set mounted on.

Are you using a front spacer to clear the stoptech kit? What size kit is it? How much negative camber are you running up front?

Thanks in advance for the clarification!

I'm surprised the 17" wheels aren't lighter. Aren't their 18" about the same weights?
My 19" Volks weigh around 19-lbs. each

But I'm sure the 17" setup is considerably lighter overall, since the tires won't weigh as much per corner.
The 17" wheels are significantly lighter. Some by about 2lbs each:

17x9" ET30 - 16.55lbs
17x9.5" ET35 - 16.95lbs
17x10" ET25 - 18.45lbs
17x10.5" ET27 - 18.95lbs

They will absolutely fit over stock brakes. Every ARC-8 size can clear stock brakes. A Big Brake Kit usually requires 1-2" more clearance than stock.
