Default Clutch will not disengage??

Had the car out awhile ago and upon launching the car the clutch is somehow stuck engaged...any ideas? I was considering replacing the clutch/flywheel along with slave/throwout. But the clutch only has around 5-7k miles and worked flawlessly before incident. Also will add that the pedal feels like I have full pedal pressure as before.

Spec 3+ with spec billet steel flywheel 5-7k
new slave throwout at same time
stock c5z MC.
Arp hardware

Any ideas on my problem??

Did you check fluid I would assume? Might try beeding if you have a remote bleeder installed, or do Ranger method from top. Some swear by Tick adjustable MC.

Hopefully you did not use ARP flywheel bolts.

There are reports of ARP flywheel bolts contacting the pressure plate on a SPEC 3 clutch. It will be interesting when you pull it apart, if you find that has happened.

Would it have started all at once if it was the flywheel bolts? Someone said they could back out or shear of it some cases. I just hate to replace the clutch being it's miles but I dunno we'll see.

And I was on the street done a 2nd gear launch (no tire heat) then attempted to heat the tires in 1st when the problem accured. I'm making 484/439 through 4.10s in a 03 z06. If anyone is wondering on the 2nd gear launch.

I doubt this is your problem but I'll share something that happened to me about a year ago. Same thing clutch would not disengage, but sometimes it would if you pumped the pedal. I thought it was obviously a mc problem until I took the clutch down and found I had a broken pressure plate It had a crack straight across the face of the plate and would release sometimes but not always. Weird.

My guess is a differential output shaft. Easy to diagnose...Jack the rear up and turn each wheel. If the opposite wheel doesn't turn, it is an output shaft.

The connection between this,and a non-disengaging clutch is going to have to be explained to me,'cause I'm just not seeing it....

Alright guys this week I'll be tearing the car down. We had about 6in of snow so I'll be taking it to the inlaws in a few days. I'm going to pull everything to get diagnosis and then go from there. If it's a clutch needing replaced it will be a monster
