dont know how this thred got swiched to talking about sus, but I have the tein He's on my car and it rides fine. Granted I had the RSR race springs and AGX's on before that (1st one in the area, bought the same time as mattback) and even the difference between HE's and RSR race are night and day. Plus slamming the car is fun! hahaha, minus the massive amounts of negivite camber in the rear...
