Next modifications are polyurethane swaybar endlinks and an aftermarket PCM. I've heard good things about both, and both together will only run about $160.
Will the polyurethane endlinks make the car ride more firmly, or just reduce sway on turns? (Mine doesn't sway much; I suspect it has the touring suspension.) And what is an aftermarket PCM?
The poly bushings just make the car roll less in the turns. The aftermarket PCM is a reflashed engine computer (Powertrain Control Module). Makes the car do things like 3rd-1st downshifts when you need them.
