They have every spring rate you could ever need. Every kit is tailored to your car. Tell them how you use your car, what modifications, tires, rims, brakes, sway bars, etc. and what you think you want and they will match the rates to the usage. I wanted full race and that's what I got. The tracks in the states are not the same as what I run on. Here they're slick, dirty, and mostly flat. I have spring rates for Sebring or Daytona with lots of grip. My mistake.
