Default Spec Twin Disk?

I just bought my C6 yesterday and drove it home (7.5 hours)

The car has a Spec Twin Disc, it just seems to engage a little high for my taste. My friend who sells Vette's says it's engaging at the normal spot, so I'll have to get used to it.

But it just seems like my Spec 5, where it's on or off, if you try to slip it, you can feel it chatter...

Any suggestions?

but boy it grabs like an SOB!!

I found mine to grab higher than my other clutches.

ECS put mine in last fall and although I'm just getting it out for summer driving it applies extremely high and basically shakes the sh#t out of the car when I try to let is out slow. I'm finding it a real nasty thing to get used to and I hope it breaks in better.

The bad news? It won't change with break-in. The good news? It will NOT slip, EVER.

If the shudder doesn't stop...it's coming out in favor of something else and I've wasted $2500.

Just a warning about it 'banging' into being engaged; I had a ram 921HD that destroyed the plastic slave cylinder leaving me stranded in no man's land because it chattered so bad. It basically is hammering the throw out bearing into into the plastic top of the slave until it pushes it back taward the rear of the car. The slave piston then moves forward out of the cylinder and dumps the clutch fluid. The good news is you can drive home at 15mph if you start the car in first gear. You have to push the clutch pedal down but it doesnt disengage the clutch disc so it bucks until it starts and then those who dont care about synchros can shift without a clutch.

Though I'd share my chatter story.

Plastic top to a slave cylinder....where are all the 'GM designed it that way so it must be good' guys now?

Mine runs smooth. I took it to the 1/4 mile twice on street tires and basically did a burn out. Since then it has been running real smooth.

It does take time to break in if you are only street driving.

Mine should be on the vehicle for several thousand by now, I can PM you the previous owner's name if you want to look up when you guys installed it.

I AM getting used to it, slowly. It's just that my RPS twin disk engaged like a stock clutch but wouldn't ever let go...

I test drove C6Dvls car to feel the Spec Twin, and it was smooth as stock. It did engage somewhat higher, but I have seen the same thing on every twin disk Ive tried so far.

that would be my suggestion. A small blip of the gas right before engagement.
