Tires
315's will require wider than stock rims. I think 10 inch is the minimum that they properly fit on. Check with TomZ Wheels (sponsor here) I picked up a nice set of ZR1s in staggered fitment. 9.5 for fronts and 11 for the back. You will be in the neighborhood of $700 for the set. He also has a few other styles for our cars.
P.S. A+++ for your signature !!!!!
