I don't know how you drive it. If you use the car a lot, the majority of your driving is under 50 mph. Plus, you would spend as much time turning as going straight. At a minimum, 3.73 gears will wake up the car. I'm sure there are others here that are more knowlegable about suspensions. There are suspension kits that shave significant weight from the car.

The trick is to figure out what you want, talk to people that have gotten their car to where you want yours to be and then copy their buildup. Having a map to follow saves a lot of money.

Again, I'm speaking from my experiences. I had a 94 GT. I bought parts for it on a whim with no plan. I bought a used turbocharger kit and put an e cam it it. I never had a plan for tuning it. I spent a ton of money making the interior look new. I never paid attention to the exterior. I wanted a date car for my wife and myself. I took the AC out of it. The engine bay looked like an abortion. I bought a G Force tranny but didn't get a good clutch. I started building a mega squirt computer and then got a tweecer. Like I say, there was no plan. Just buying crap - expensive crap. There was nothing wrong with the individual components, just a lack of planning.
