If you are looking to have a better handleing and stopping car... I'd part out the wreck if you need the cash first and buy a brake up-grade and add 4 wheel discs. As for suspension there are tons of kits and parts out there. Just changing to a 1" sway bar up front and adding a rear sway bar will make a big difference. Poly bushings front and rear will also help. I did the latter on my convert. Made a huge difference!
