For the track folks are you running a 19” or an 18” wheel? I have a set of Shelby New Gen wheels I’d rather not mess up. So I’m in the hunt for a set of track wheels. Right now the front runner is a set of Shelby GT350 wheels which would give me a wider tire option and run a 305 square. Any and all advice welcomed.
TIA

My tire option right now is the pilot sport cup 2s.
