Had the Exedy Hyper Single installed a few weeks ago. Today was my first track day, and I'm getting a vibration or low moaning sound above 100 mph. Did 2 short sessions, and stopped for the day. Replaced items: Clutch, throwout and pilot bearing, Cobra Jet pulse ring, MGW racespec shifter, Ford Racing clutch line. Still have stock 2-piece drive shaft. They may have disconnected it from the diff because I see bright orange paint on the rear driveshaft flange. Would re-installing it a 1/4-turn from original spot on the differential cause vibration? Anything in the clutch that could cause it? Hate to lose Sat and Sun track time because of an unknown noise/vibration.
