What tires are you using? Is your car a base Crossfire or an SRT-6? Tire pressure is not the best way to compensate for suspension calibration.
I'm running a new set of Dunlop SP Sport Maxx TT's at OEM sizes with OEM alignment specs and manufacturer recommended 36 PSI on an SRT-6. I don't have a lot of understeer. The SRT-6 corners flat without tire squeal and very little push. Any understeer is very controllable with trailing throttle oversteer or throttle or steering. I like the setup. Just enough understeer at the limit to make the car easily controllable. And grip levels are pretty damned high. I actually worry more about the opposite problem. The car can be a bit tail happy with this much low end torque in a 3,200 lb car.
Other good street tires...Continental Extreme Contact DW's, Bridgestone RE-11's.
