i dont know specifics, but i would not be surprised to find out that corvette
runs a specific VIR setup and so on.
Danny felt there's another couple of seconds with further tweaks and fall air. 1:56's for TTS/ST2
Makes you wonder where the bottom is
A TTA corvette isn't going to find 4 seconds on a shaker rig w/ shocks, with no aero and no trans gearing changes, decreasing time will be through tire selection/pts planning and just tons of little details. I've always said there's a 2:01 in TTA, but conditions would have to be perfect and there's probably only 1 combo of tire/pts/weight/shocks that'll work. Also the race differences between that ST2 car and PTA would be huge, a PTA corvette would never have the brakes/tires to run that hard that long.
