Default Can you run 315 x 18 Hoosiers in front on a C6 Grand Sport / ZO6

I have a 2012 Grand Sport and want to try running 315 x 18 Hoosiers on the front and am running 325 x 18 on rear for auto X.
Was running 295 that are cording and have a number of 315 laying around. Is anyone running 315 without any rubbing issues before I install?

I'm running 315 Hoosier A7's on the front of my 2011 Grand Sport. No issues. Just a minor rub only a full lock, but I don't use full lock on course. Rears are 345 Hoosiers. They also fit fine. CCW Wheels, 18x11 Front, 18x13 rear.

You burn through fronts 2x to rears?

No, wear is pretty even.

I am running 335s on the front of my car. No rubbing issues other than you lose some steering lock from interference with the brake duct and inner fender.
