Help me choose suspension setup

After losing 2 races to a bolt-on Eclispse turbo awd last night, I realized that besides practice, I desperately need better suspension. I spin through first, and all of 2nd as well if i shift hard (I even left about 3' of rubber from the 3rd to 4th shift:lol: ). I realize that this is largely due to the 4.10's, and although I love the available power from them, I don't like how quickly they run out. Anyways, my question: What springs/ other components should I get to help me get traction as well as handling. I have been looking at the pro-kit, but I don't know if this will help me in a straight line, and vice versa for the drag kit. I plan on getting used parts, and my budget it about $500. I'm thinking some sort of springs, c/c plates, and maybe sfc's if they will work with my cat-back. Please help me narrow down my list, and anything else I should have on it.
 
Its going to be hard to make your car handle very well in the twisties and launch well drag racing. The spring rates are entirely different, and require different setups. The best bet would be coilovers, but those can get pricey. If you want a decent all around setup, get the Bullitt suspension package.
 
Lower control arms, full length welded subs, and a set of springs. If you do the work yourself you could get all new parts and still be around $500.

I have the Steeda aluminum lower control arms, kenny brown full length subs, and Eibach Pro Kit.

Good Luck
 
Does anyone happen to have a picture of full length sfc's on their car? I may be able to fab up some if the MM ones won't work with the side-exit. My dad owns a foundry and I can get pretty much any metal work I want for free, including welding.
