Can you run a 315 on a lowered vehicle? I plan to do the DMS springs. i was looking at the AFS 11in Zr1 style. I know rolling of the fender is in need, but what else has to be done?

What are the pros/cons of the 315. Handle better or worse?

Also i heard that i need the Gran sport offset, what size is that exactly 36mm??? Does anyone know if thats available in the polished wheel?

Also, does anyone make a 17x11in ZO6 wheel??
