    Depends on tires and suspension. I usually ran about 38 front / 32 rear for typical street tire class tires.

    When I was running slicks in the C5 it was 30/39 front/rear. Sometimes id run it down to 28 in the fronts. Always had to had more in the rear, could never keep the damn thing planted until the new rear end went in.

    Chalk on the sidewall will show you if you're rolling over the tread and onto the sidewall in the hard corners.

    Put some on, if you see it worn off the sidewall, you need more pressure.

    Were you running staggered tire sizes? That'd have a big effect compared to an f-bod. Heck, the IRS on a Vette vs our live axle is another reason vette pressures won't be too comparable to an F-bod. Something about rear camber (and toe)..
