If you do not have a BBK, and your lower spring perch is above the tire (stock style struts, or proper coilover setup) then no spacer is needed up front.

The 17x9.5" ET35 wheels were even tested spacer free on a non-M Z4 up front.

Yes, I'm using 12mm spacers up front to clear not only the front calipers but also to clear the tires from the lower spring perch.

I have the Stoptech 355mm kit with the ST40 calipers. Camber is set at 3.0* front and 2.7* rear. Rear wheels are spacer free.
Thank you for the details.
