The Konis made a big difference on ride. Haven't been able to get to the track to see how the high speed handling is going to be. Stock, it was horrible. The car wanted to dart around and rock from side to side under full throttle. If I can get to the track and the car is stable, I might not worry about springs. But if the car is still unstable (To me) I might think about it.
