High performance plate- from the old AP Racing division.
Bonded rally/race type 180mm wide clutch plate which is ideal for fast road and track days.
This was the most commonly used performance plate from the AP Racing section and originally claimed good for 140ft lbs, but see the new Mini Spares/AP clutch plate
C-AHT595 tested to 10,000rpm and destruction by AP raicam which seems just as good but less expensive.
