clutch sticking after aggressive driving

^ Throw out bearing noise. I'm assuming yours is still new so the noise is not as noticeable, but give it a few months and it'll come back. It is quite normal.

Clutch sticking... is this the same feeling under super cold temps?

no. under cold temperatures everything feels sluggish, like the clutch, steering wheel, even lcd displays. that's normal and caused by excessive viscosity of the fluids due to low temp. in my case, i was on the track, so temp was at least normal if not more. and the clutch pedal was not sluggish, it was completely stuck. it didn't rebound on its own at all and i had to pull it up with my foot. it only happened once after a long drive on the track, but i left the track right after and it didn't happen again. another member here also had a similar problem while drag racing his car. haven't seen any updates from him about a cause or solution to the problem.

No... not talking about throwout bearing noise or gear lash noise.... I'm talking about a physical knocking sensation felt in the pedal when the clutch was disengaged (pedal depressed). That is not normal and indicative of a problem.

That was a separate issue that was resolved with the clutch assembly getting replaced. My clutch now feels better than it ever has in this car. Engagement is also smoother.

I think the issue of the clutch sticking to the floor after aggression stems from the slave cylinder, unfortunately. Seems like I'm not the only one that has had to have the slave cylinder replaced.

I vote you boiled clutch fluid. I did it at buttonwillow, clutch went to the floor and stayed there. It was about 100 degrees out and me and a friend were running the car in back to back sessions. Pulled off the track let things cool down. Pumped it a few times and clutch came back. When I got home I changed to high temp fluid and I noticed the clutch line gets fairly close to the exhaust (I have hfc's which might have contributed to the problem). It even has a little silver sweater on it to protect it from the heat. Other folks may have had clutch failures but if your pedal came back or was fixed with a bleed you prolly just got it too hot.
