Hey Everyone!! I have a 1996 GSR, 5spd, lowered, and a cold air intake. When driving at 1/4 throttle, everything is fine but if I go over 1/2 throttle in first and second, or full throttle in 3rd, 4th or 5th, I get this horrible loud metallic rubbing sound as if there is some contact between two metal parts somewhere. It seems to be coming from underneath the car between the engine and the firewall. the car is pretty low and I hit speed bumps underneath no matter how hard I try not to. I am raising the coilovers back up but until then, I need to fix this problem. Any ideas/?
