Had a customer come through with a Exedy Heavy Duty clutch kit (FJK-7123HD) from Exedy locally. Opened the box and on closer inspection, realised the clutch and pressure plates are totally different from the Japanese Exedy Stage 1 Racing Clutch, which to most of us, have been known to be exactly the same.

Also went online to:
Exedy - Spec Sheet
and the finding was shocking!

Will post up info and pics shortly.
