so i installed KYB AGX's last spring(early april) now suddenly the ride seems much more rough than i can remember and i feel every little bump. i have them sitting on ebach springs that i have not replaced and were on the car when i got it. i have the agx's set on 2 in the front 4 in the back as recomended. the ride doesnt seem to be bouncing so i dont think there shot well i hope not at least... and i have 18's w/ 225/45/18 on it. any idea what would cause this? could it be the springs? thanks
