Lower the rears slowly from 29psi until you like the feel.
I've tried a stiffer front swaybar at the track and find that it adds to understeer, so I've gone back to a stock one. If you're looking to not invest more in parts, then the front sway bar may be one thing you want to defer. Best to try it back to back so that you can compare it for your driving style.
