I have a set of the Swift springs that the Spec Racers use. They are 500 lbs rear and 450 lbs front and work with the PSS9 coil overs. They lower the car an extra inch over the PSS9's and are a more agressive track spring than the PSS9 springs. I used them 2 autoxes and took them out . $400 new price and I want $200. PM me or
