I recently bought a 1996 GTR with an unknown single plate heavy duty clutch installed by Hills mtorsport a few weeks back.
First thing i noticed was the clutch grips extremely high on the pedal making it very awkward to drive, got used to it quickly so no probs. This arvo finally gave it a decent launch at about 5000rpm and took of nicely with no slip. The problem is after the launch the car wouldnt engage gears when the clutch was let out, it would just grind. Let the car cool down and afterwards was fine. Second problem is wierd, when you turn the car off sometimes it "hops" a little as if you let the clutch out with the car on.
Could it possibly need adjusting? Is the pick up point odd? Could the slave cylinder need adjusting? Otherwise the clutch is fine and does not slip under load or launch.
Any advice would be appreciated.
cheers
