Anybody got these on an M?

I've always liked the rota grid wheels. They look similar to the ones on the m3. Rim style do them in 19s to fit z4m, albeit in black. Iirc, they have a nice dish in the rears.

If you click on the technical info, the offsets for those are:

This is the available fitment for your car:
Intended Axle Size PCD Offset Notes
Front Axle 19 x 8.5" 5 x 120 ET40
Rear Axle 19 x 9.5" 5 x 120 ET45 Includes 5mm Spacer

They look like non-M offsets to me.
