Seriously, get a set of OEM 18 inch M3 wheels for cheap and put some dedicated snow tires on them (Bridgestone LM, Dunlops M3, etc). I have a 2006 ZCP as well. Car handles awesome in the winter WITH proper snow tires. Don't be scared...cars were DESIGNED for all seasons of the year, not just three seasons. How do I know?....becuase I'm a mechanical engineer!
2006 M3 ZCP. Interlagos Blue on Dove Grey. 6 speed manual.
Eibach Pro-Kit / Koni externally adjustable F&R shocks / DDM Aluminum Pedals / BMW Performance Short Shift Kit / Clutch Delay Valve (CDV) removed / Painted reflectors / Stealth bulbs / Turner 15mm/10mm front/rear spacers.
