    I ran 34/32 hot this weekend on my new Z51 Vette--but don't know if that's too low, as I saw some rollover. ~3520lbs w/ me in it.

    Anyone been experimenting w/ pressures out there & what have you come up with?

    TIA

    I'm guessing that's too low. The RE-71 looks to be a lot like the Dunlop, which likes higher pressures on heavy cars. I might start with 34/32 COLD next time - maybe even more differential if you felt like the car was understeering at 34/32. Maybe something like 40/35 Hot.

    Will do--I'll give it a go this weekend @ a concrete venue. Thx
