If I'm RWD, I like to go down to 25 PSI. AWD cars I don't mess with it. I haven't had an AWD car that could break all four wheels loose..... yet. The Q is tuned and hopefully I'll get to run it this week at test and tune. It won't be near my Stinger numbers but if I break into the 12s I'll be happy.Hey guys I’m going to the track on Wednesday. Just wanted to see what the psi I should have my tires set to. I have a gt awd. Thanks!
