Tire Rack lists two winter wheel options for the M3 Competition Package (ZCP), Sport Edition F5 and Borbet Type TS; yet only one for the Z4 M Coupe, the Borbet Type TS. Atleast one user here has successfully done the Borbets.

Think the Sport Edition F5 will work on Z4MC? If a wheel/tire fits the M3 ZCP it should fit a Z4 M right?
I would much prefer the Sport Edition F5s over the Borbets since they dont require spacers or lugs, and are cheaper. I'm not worried about TPMS.
Thanks much!
