I agree with the above posters. The arospeed springs a subpar in ride quality and performance. Go with either a coilover setup (D2 suspension, ground control/koni, tein, somethign of that nature) OR a good shock spring setup, koni yellows and eibach or such. dont slouch on your suspension, you will regret it, when your bouncing up and down the road on blown shocks, or becuase hte spring rates suck.
