Running a KEP stage 2 pressure plate with a lightened original flywheel and 930 clutch disc on the turbo, pleased with this set up.
Some people seem to have had problems with this set up, but was apparently caused by too much crankshaft end play (worn out main/thrust bearing).
Haven't had this problem but mine was fitted on an engine with new main bearings and virtually no crankshaft end play.
The pressure plate is quite stiff and some people suggest fitting it along with a new clutch fork, which isn't quite cheap.
In any case it is important to set the biting point quite low, as a short pedal travel prevents from applying "excessive", unnecessary load on the fork which has to work against a pressure plate much stiffer than the original's.
