Sway bars can decrease your performance if not chosen correctly with the rest of your suspension. They are just one of the variables in the suspension system. Take your time and read read read and talk to people at HPDEs. It is better to drive your car as is at one or two HPDE and then make improvements based on that baseline.
You can fit 255's in front? I thought most I could go without rolling the fenders was 235.
