315s will work, if you don't care about the brake duct and you don't care that the tires will stick out from under the fender lip. But you'll have trouble with TC since the taller front tires will make it appear to the computer as if the rear tires are going faster than they actually are.
I'm thinking of running 315/30/18 all around this year on stock rear speedlines myself. With the shorter profile 30 series will I experience alot of rubbing? I'm planning on using Kuhmo XS street tires.
Ive heard people say its fine and others tell horror stories of rubbing the fender. whats the truth?
My car is lowered all the way on stock bolts, would simply raising the front a bit alleviate any issues?
