First off thank you for your time, you're input is much appreciated! And sorry if I posted in the wrong section. I guess my question is rhetorical since i did study this matter thoroughly but I would still like to ask it in case I have missed some magical cure or something of similar nature . I recently purchased 02 Z06 and I love it! Everything was perfect till you guessed it, clutch started to stick during spirited driving. At first after some 5-10 min. of high rpm's now just one second gear pull till 6k is enough and half of the clutch pedal travel is gone. As soon as the first symptoms of the problem occurred I did bleed the system, to no avail. I removed two plastic covers as someone recommend on this forum and bled the system again, which changed absolutely nothing. I changed master cylinder for another stock unit (car is stock) and bled the clutch for the third time just for fun! actually feels slightly worse.. So my question is am I stuck with the only option of changing the clutch, slave cylinder etc. or is there anything else worth trying before this step? I do love the fact that it is bone stock and would hate for someone to take it apart if that is avoidable..
Thanks in advance!
I also own a 02 z06, shortly after buying clutch started sticking to the floor at high rpm shifts. Tried everything to no avail. I installed a tick adjustable master cylinder along with a remote bleeder, replaced slave cylinder as well. I left the clutch alone cause it wasn’t slipping. I also removed the assist spring on the clutch pedal. I still have the same problem but not nearly as bad. After spending hours after hours reading on this subject, I personally believe the root cause of clutch pedal sticking to the floor is the pressure plate and the centrifugal force exerted on it. I’m just waiting on my clutch to go out before spending cash on an after market replacement assy. My Z currently has 123,000 miles on the stock clutch and pressure plate.

It seems that way. I guess new clutch kit it is...
Hello, Several years ago rt after buying my 32K mile ZO6 the clutch started sticking to the floor. Forum told me slave cylinder. Tore the hole thing apart which was a big job entire rear suspension with trans and torque tube etc The clutch was good but there was no way I was leaving it since I did not want to do this again down the road. Put a C6 flywheel and whatever clutch forum members told me to along with the new slave. Also put in a remote bleed. Paid super attention to aligning the spine with the spline tool and reassembled. Never had another problem and its been 8 years.

Thanks for sharing! I don't suppose you remember what must be changed during this process? Like some sort of gaskets or seals?
And could someone educate me. Is there any difference between Z06 and Base model clutch, pressure plate? I assume slave cylinder is the same.
You need to buy a clutch kit, that will come with a new flywheel, clutch disc, pressure plate, and pilot bearing. You also need to buy a new slave cylinder and also a remote bleeder, makes bleeding the clutch a lot easier. Check out your torque tube, spin it and see how it feels, might need new bearings and couplers.
There’s no gaskets that need replaced and the only seals that you could replace would be on the rear diff where the axle shafts slide in. You could replace the rear main seal on the engine if you wanted too.

The reason im asking is because I preferer buying me parts from rockauto.com (cheeeeap) and they dont specify if those kits are for Base or Z06. So before I spend all my hard earned money I just wanted to make sure that they are all the same?
Gentlemen! Spring is rapidly approaching, or so they say.. And I am back to beg for your infinite wisdom! . I have chosen a clutch kit (04173 from Rockauto.com) but I cant really confirm that it is indeed stock Z06 replacement. I did my research but opinions seem to differ. Some say it is identical to stock Z06 clutch (disc, plate, fly.) others that the disc is from Z06 but the pressure plate is from base. And then there are those who claim that 04905 Kit is stock C5 Z06 kit, or those who say it is for LS7. Can someone please educate me on which one of those two is standard LS6 replacement kit.
Thank you in advance!

Good call on changing everything. Seen many cheap out on changing clutch assembly for x amount of money even if the clutch had low miles and still experience same problem. Now you can be trouble free for for 70 80k mile. Will depending on your driving characteristics.

Oooo I have cheeped out so many, many times before, thinking this must be the time i'll get lucky . I never did get lucky... So this time i'll spend the extra buck and get all the standard bits (slave, release bearing, remote bleeder), as well as drive shaft bearing and torque tube bearings. Am i missing something?
Time for a new clutch unfortunately. Mine had your exact same symptoms but a new master and a bleed fixed it. But yours def needs a new clutch. Be sure and do the two rear motor seals, inspect the torque tube bushings, and it may also be a good time to reseal trans and diff while they are out.
here are the part numbers for arp clutch bolts
