I drove my CGT during a track event ( the clutch thiness measures out fine ) after 3-5 laps, the clutch pedals goes soft on me ( clutch drops all the way / no resistances ) has anyone ever experince this ? The brakes are fine, but the clutch just goes , i thought this car can serve some light track duty ? ( Cal Speedway Roval )

When was the last time the car was in for service or you had the clutch measured? Sound like a possible slave cylinder. Most of the time they fail you will have an external leak from it and you will lose brake fluid from the same window the clutch is measured through. Would be impossible to miss when in for service or measuring the clutch.
Easy, preliminary check is checking the brake fluid reservoir in the front. Would have to lose quite a bitch of fluid for you to be able to tell from the front but just a thought

your clutch uses brake fluid to operate....it is boiling and that is what leads to mush....after it cools down it is okay. start with a complete flush and a better fluid,then heat insulate lines

had the car service 3 month ago, the clutch measured over 30, the car drives fine on the street, on moderate pace on the track the clutch holds up, when driven very aggressively on the track, the clutch goes, so maybe the fluid is boiling.

If your foot is resting on the clutch at all while driving at high speed on track you can boil the clutch fluids. I am not saying that you are doing this as I don't know your experience on track, but that sounds like the problem. It is a very common problem for amateur/beginning drivers driving manual.
Again, just a suggestion

Exactly, totally agree. Had this happen to me also. Take it easy for a lap and the pedal comes right. Make sure a trained technician services the car, the bleed screw for clutch is a little tricky, but must be done every 2 years max. with the brake fluid. Or preferably before any track time.

Sounds right. Porsche's recommended service interval for brake and clutch fluid is every two years but track inspection forms require 1 year max. I agree with 1 year for tracked cars.
Let me know if you would like to move forward with this service
