RET_COP Lou every car company builds there own frame and body. The best thing I can let you is to start with the spring rates the company comes up with when they sell the kit. After everything is togeather, all the fluids full, half tank of fuel in the car, battery in the r/r corner of the trunk, get the car weighted with you in it. Have a wheel alignment done after ride height is set and weights are done both diagonally and front to back. If you are rally serious have the bumpsteer also done so that both front wheels are turning the same radius. After this you need time on the drives seat and take pictures of the car going around turns, right to left weight transfers, see how much the car leans around shape turns. Fromt here you go to stiffer springs about a 30% rate increase over the ones that came with the car, better shocks like QA1 with dual control for compression and rebound. Your street setup will not work well on the track. You will also take a beating running a track setup on the street. Getting your self a Kirkey road racing seat will help alot by not having to hold your weight in place when driving hard. If you are going to track the car, 2 important things to look into
#1 pay a 2 or 3 quart accusump and have it hooked into the oiling system. this will prevent lossing
oil pressure around high "G" turns. Also work great as a preluber for starting the motor.
#2 add 1 extra quart of
oil to the motor for the same problem of high speed turn and
oil not going back into the oil pan fast enough having the pickup uncovered and have the oil pump sucking air. This will not do any damage to the motor. There are a couple of suspension books to look at. I good driving school is another thing to look into. IF you have any guys around where you live that are into dirt track racing, they have scales and know alot about seting up cars and suspension ideas. There is about a 50/50 about weather to go with higher rated springs and small sway bars and the other idea is larger sway bars and lite spring rates. The angle of the coil over springs has somnethings to deal with too. Rick L.
