If you want to put the money in the car, and not into equipment and whatnot, I'd recomend a polyurethane bushing set. It'll tighten up your suspension like nobody's business, and feels great through the cones. And unlike many other suspension mods, it will actually help you uncover your driving weaknesses, rather than just hiding them. :thumbup:
All these people recomending brake stuff.... I wish I knew what it was like to need brakes for autox

h: ......so slow....
