i still get an occasional gear grinding/missed shift while downshifting from 3rd to 2nd on the track but it only happens after 15-25 minutes of lapping, and not at the beginning of the session. I also feel the clutch pedal getting a bit softer (not sure if true or just a false perception). The Motul fluid is about 6 months old now with 7 track days on it. I still believe there is a lot of heat going into the clutch lines causing boiling over of the fluid and sticking pedals and gear grinding. Next summer I might consider upgrading the clutch lines or maybe wrapping up more heat insulation around it.

thanks for your help.i too was having similar problem.

I have had my clutch stick to the floor after 3 hours of really intense traffic but that is due to over heating. I too have had the same problem you are describing. When i do hard shifts starting from a stop position and i shift quickly i have had the clutch pedal stick to the floor for a quick second. I wouldn't worry about it though.
