Where did you get your information that decreasing rear rebound will induce more oversteer? Everything I've read says the opposite in regards to damper tuning, plus, my real-life auto-x & track experience backs this in my STi. Stiffer rear rebound = a looser back-end; also backed this opinion by a National Champion in Auto-x. "Entry Understeer - Increase the rebound of rear shocks. Decrease the bump of front shocks." Stiffer rear rebound = stiffer rear end = more prone to oversteer; not understeer. How is stiffer rebound not tightening the rear end?
