I did vary tire pressures to see if it would help. Started at 32 cold, tried 34 cold...no change, went to 29 cold... a little better. Both days were unusually cold at around 55 degrees F. Probably worst conditions for old front tires. It was difficult to get heat in the tires and the track was nearly always cold. About 3pm on the second day the sun came out and warmed the track. We saw a lot more grip but still had understeer in the suspect corners.
