Do a search on suspension in the forums. But a quick summery is as follows:

Drop/performance springs (1.5-2")
Shock and Strut upgrade
Wheels ( the smaller the wheel the faster you will get up to speed. The larger the wheel the better track/turn performace you will have)
Tires (better grip gets your power to the ground and your ride moving)
Control arms (keeps those wheels from hopping)

Those are the basics and you can go from there, but get the basics done if you want your pony to turn.
