http://www.toplineparts.com/frameset.html should help you with the overhaul. You can also get coilovers from them. If you need more info, I reccommend calling. John is one of the nicest people you'll talk to. Your upgrades are all what you want to spend. You could go all the way up to H&R if you want an all out race spring or keep a smooth ride with the Topline. I hear alot of people say "the OVERPRICED H&R spring", but they are forgetting it is a race setup designed and handbuilt by the leading suspension manufacturer in the world. Nothing against anyone else, but you really can't compare. You could also go with a full coil-over set-up as the one on the S.B. on the Topline site. He's running Carrera (not the Porsche) full race coil-overs on all fours. Lots-o-dough. So it all depends what you want to spend. $400-$3000. I also remember seeing coilovers on the old GL site. I think Superman could help you out with the name. JJJ Designs maybe? Upgrade your swaybars. Add one in the rear. The Topline strut tie-bar is one of the best investments I've made. I reccommend that. If you can, go for a Kafer cup style ti-bar for the rear. It'll tie your rear suspension together and your framehorns which means more traction. Once you start stiffening, you're sacrificing ride quality. Keep that in mind also.
