who's running 255/40/17 In FRONT!?
 

I need to know if your rubbing under hard cornering and what wheels are u running them on.. Please tell me width and offset please.

I'm using 255/40/17 on Supra Turbo wheels, which are 17x8 in front with 50mm offset (offset is same as stock FD). They rub when cornering and changing elevation at the same time. Just plain cornering doesn't cause any problems. I am on stock suspension, so coil overs might have no rubbing at all.
