It's all about the tires, you can run 305 front 315 rear cup 2s on the stock gt350 wheels without an issue.
Good point.
I've considered this but I was thinking it would change the balance of the car. It's so good as is. For me as a novice I would rather not have a track car with a tendency to oversteer.
Maybe it's my driving experience...? But I can definitely detect the understeer characteristic. It's very safe though, you're right. I don't have new wheels yet but I just recently put 305/30-19 Hankook RS3 V2's on my car. Despite the 10.5 front 11 rear widths, it's working just fine and it's biting harder in the front. Once I figure out a 19x11 on all 4 corners option, I'm going to switch my RS3's onto those and put my Super Sports back on the factory wheels for DD'ing and the 19x11's for racing.
If one has the money, a great option. If we're splitting super tiny hairs, I actually think the 11 front 11.5 rear is actually too wide for the 305 and 315 setup. I like the idea of 10.5 on a 305 and 11 on a 315 to 325. I like to try to get more than 1" of tire wider than the wheel and no more than 2" at the very most.
