Lots of pre race questions.
Well i finally got some time off and i am getting the car ready to race. I had a few questions though.

What chassis software is everyone using to setup their 4 links? I downloaded a demo version of performance trends 4 link calculator and it seems to be ok. Would 4 link wizard be any better?

I took a wild *** guess on the spring rates, i am running 85 lb in on the rear and 125 lb in on the front. They are both 12" springs. Do those rates sound about right? Guessing the car is about 2200 lb.

I have access to a set of 4 corner scales. What bias am i looking for? I have an adjustable sway bar on the rear and coilovers on the front. Should i preload the right rear a bit to try and get the car to launch straighter, if so how much.

I know there is no exact answer to some of these questions but i just want to get it as close as possible before i run it.

I am running ET streets on the car right now. I don't have any tubes or screws in them. Do i need to worry about them spinning on the rim or should i go ahead and do it now?


TIA
