I'm building a 93 del sol turbocharged track car. I don't know a lot about suspension but I want to lower the car and stiffen the rear Springs and keep the front about the same stiffness. so I can get as much traction as possible on the front tires. My budget is what ever it NEEDS to be. I'd like to save money where I can but Ill buy what I need to to do it right. Thanks!

 

I like Progess myself. I use them on my EK with 350/550 spring rates. It worked very well with the 205 Ra-1's. The Koni yellow/swift spring combo is popular option that a lot of people use.

 

+1 on the Konis. You can contact ground control and have them make you custom sleeves with whatever spring rates you want.
