I would look into getting a set of lower control arm for your rear axle. This will stop axle hop when you take off. Next thing I would look into getting is a set of springs and caster/camber plates. Depending on what kind of driving you are going to do with your stang, they have different kinds of springs and setups. If you want to have awesome handling, I would drop your car about 2". If you want a good launch, then a drag setup would work out great. Keep this in mind, it's very hard to have both "setups" on your car. Your going to have to sacrafice something for something else. Also, you might wan't to get some chasis stiffing devices, such as sub frame connectors, strut tower braces (more for Auto-X, you don't need one for drag racing), etc.... Hope this helps you out
