When we first started running in IT we ran cold pressures in the area of 35-36. The car was very prone to locking up tires under braking. Lower pressures seemed to work better.
Since Road America and Blackhawk Frams put a lot of pressure of the left nfront we tried staggering the pressures.
We settled on 27/LF 28/RF 29/LR 30/RR. The hot pressures is 35 in all four tires. The car is loose for the first lap, so some caution is needed. Try this. I think you find it works if you have your corner weights right.
We have run 2:46s at RA and 1:23s at BHF.
