New M3 on BMW website.

The concept M3 had the wheels you see in this pic (this is a concept csl press pic), which are also the 19 inch option for the regular m3. When buying the CSL, you get these 19 inch wheels standard, but almost all CSL buyers opted for the split spoke CSL wheels with semi-slicks that you see in most csl pics now.
