Well if throw of the slave piston is within specified range, & the clutch hydraulic system is holding pressure when it encounters resistence, then this suggests the issue is forward of the slave piston in the bellhousing. However, also worth confirming that your clutch pedal is correctly setup & adjusted as per specs in the workshop manual.

If all the hyd side of things is working, then I would suggest the problem is further it. Gearbox out for clutch inspection......

HD Clutch, Lightened Flywheel and all oil seals for engine and gearbox...

At least it'll be worth your while :)

I would not be considering a lightened flywheel- some people would avoid buying a car with a lightened flywheel. You did not mention any other info about the car- like model KM's etc. If it is just used as an ordinary sports car then a clutch kit - use the OEM brand Exedy and a standard clutch will do the trick for many further km's. I would guess the pressure plate fingers have collapsed. Standard practise is to reface the flyweel.

clutch free play on the pedal ie under dash is probably the same adj regardless of clutch set up. The way to check engagement is merely select a gear - put the hand brake on and then lift the clutch and you will see when it takes up. Why not just return the car to the fitter and ask them to do it for you- that is part of the job. Probably take them 5 mins. PS repair manual should have spec. PS as a logic if there is no free play the clutch will start to disengage immediately you apply pressure.
