997 Cup Driveshaft, I do not have mileage on this shaft. It is a motorsport GKN driveshaft. It does appear to be in very good condition but I have not taken it apart to inspect. Not recommended for actual competition but would be perfect for testing or a spare. Since we have started to use the throttle blippers, breaking driveshafts is occuring less frequently. Contact us about a throttle blipper for your 997 Cup with a sequential gearbox.
