GM T5 with stock hydraulic throwout bearing potential release issue...
I think I have about .210" gap between the clutch fingers and my throwout bearings most collapsed position.
Is this too much?
Anybody know the overall throw of a GM T5 or T56 Hydraulic throwout bearing?
Anybody know how far clutch fingers need to move to fully release?
I am trying to see if I have enough throw at the HTOB to fully release my clutch. The trans is acting like the clutch is not fully releasing. It is close. However, 5th gear is giving a little crunch if the rpms are higher than about 2K. This is for a racecar, so 6K rpm shifts are required. Anything beyond 4K and the trans will NOT shift into 5th gear. Even with pushing the clutch in and holding it down.
Thanks in advance!

Most of what I'm finding is for full blown race stuff. This install sheet for a stock clutch and aftermarket bearing tells you to target 0.060. All of these numbers are also probably assuming a new clutch, you can get by with less on a used one (the fingers come out more as the disc wears)
Nice. Count on grm to help with your Mazda rx7 with a Chevy venture engine connected to a camaro trans with an s10 clutch resting against a cavalier flywheel.
Rob, I'm measuring about 5/8" of travel on the old T56 slave cylinder I've got on the bench - 3 7/16" fully extended and around 2 13/16" fully compressed.

That's pretty similar to what my aftermarket T5 slave cylinder does. With it fully compressed, I have a little under a 1/8" gap to the PP fingers.
