Need help with Tire Pressure for track and twisties
This weekend I attended a few car meets and had the pleasure to meet some ZL1 owners (not on this forum unfortunately) who track their cars at Laguna Seca. Thunder Hill, Sonoma raceways.
Now, I am getting real close to having my car done and almost ready for the track and we got on the topic of tire pressure. I was always under the impression that a lower tire pressure at around 28 psi cold and no more then 35 hot was the sweet spot to get optimal traction. (I believe the track manual even say's the same thing)
I was told by these guys that 40Psi cold was a great start and that their track time were much better with this PSI. I wasn't completely convinced until I talked to another ZL1/1LE owner and he agreed with the higher PSI on Thunder hill and Laguna Seca.
Anyone run these higher PSI when on the track or even on the twisties for a day of spirted driving?
