I may have to update this and look back and forth a few times to help.
The JIC pillow tension rod, will make handeling and suspension feed back more responsive. It has a Hard Bushing so there is no Angled rebound on the suspension like w/ the stock bushings. ( instead of it bouncing like this, / , it moves like this, l .)
There is alot of very serious applications that will help. You can go as far as Replacing your Rear Suspension Sub frame for an S15 Sub frame for a tighter rear end.
This is a small list of JDM parts available for your car: http://www.automotiveforums.com/index1.asp?cat=239
Camber is measured by + and - degree. You may see a car with the rear tires sitting with the top leaning inward towards the car, this is - camber, + camber is where the top of the tire leans away from the car.
Depending on what your setting your suspension for is how Camber is determined. basic road driving should have 0 Camber. and 0 Toe. (Explain Toe later). If your Drifting or Circut racing a -2 front and -1 Rear is good.
Elaborate a little more on what you want to do.
Peace
