Definately get your suspension set up for the supercharger. This is what I would recommend. First, one peice driveshaft, I have the Coast driveline aluminum model, great mod, gets rid of all the driveline slop and drops 20 lbs, there are several companies making them. Second, upgrade your springs, I have Steeda sport springs they work very well,and I added Tokico D-spec adjustable shocks and struts with an adjustable panhard rod. Third, adjustable upper and lower rear control arms, upgrade the rear anti sway bar, and add front sway bar urethane bushings. fourth, Rear end gears, I got 3.73s and I love em'. You probably won't need upgraded brakes unless you intend to autocross or road race. Anyway these are mods I did before supercharging, they make a big difference in the way the car handles, and you will need them for sure once you add all that power. These cars are really scary if you add a supercharger without the suspension being beefed up to handle it. They can get really loose in the rear and the body roll can be terrible, some guys have lost control and ended up crashing or in a ditch. Mine had nitrous before the suspension mods and I can tell you firsthand it's scary! These mods will settle the car down and make it very easy to control if the rear end slides out. Anyway, hope this helps. Oh,by the waya Kenne Bell or whipple twin screw will give you the absolute best driveability on the street. Unbelievable torque and an incredible holeshot, it's like driving a big block with tons of power at any rpm. Mine starts building 4psi boost at 1000 rpm. Most guys I've racedare in my rear view mirrorbefore I get out of second gear.
