The 3+ is an over weight, unbalanced POS! I ran it for a year and it totally screwed my tranny. How much power are you gonna be making? I am running close to 650 ft lbs to the wheels on a 150 shot. I have made several 4000+ launches on full slicks and my Spec 3 has not blinked yet. Dont get the 3+!!
Also... look into a Tick Master cylinder when you do the clutch. You will need the adjustment or else the clutch will disengage on the floor. The Tick master also flows more fluid so you can bet you wont be missing any shifts after the install.

However, how does the torque tube load the synchro's ? The inner shaft on the torque tube is fixed and does not have any front or rear movement.

I have about 500 tq to the rear wheels, and it "says it will handle 599". I just wondering if they rated them correctly? I have the stocker in yet, but it's on borrowed time.
I had a spec stage 3 in my ta and it performed great, but was aggressive on engagement. I want to get a clutch that drives like stock but can hold the power. Also I'm not willing to drop over a grand for a clutch.
I was looking at the spec 1 or 2 with an alum flywheel. The car is 99% street driven.

the synchro's have to get the shaft inside the torque tube/clutch disk moving to whatever speed is needed for you to change into whatever gear you're going into.. not complicated. and more weight is indeed more load on them

The pressure plates are all about the same weight on a single disk clutch unless it's made of aluminum. Generally wing style puck disks are lighter than full face. Spec 3+ is full face, but metalic which seems heavier than organic. The lightest single would be a wing/puck setup with a solid hub, but I don't like solid hub disks on the street.
Other cars are not burdened with a driveshaft in front of the transmission like a vette. I have a 3+ in my car and it's ok, but fast shifting isn't the best which may be due to the clutch releasing low to the floor though. I'm going to try a tick master to get the clutch up so I know it is fully disengauging when I try to shift fast.

It's not as bad as your experiance, but could be better. The clutch release point is actually higher than the tex I took out before it. I have a new slave, remote bleeder, but no shim. The shim debate has been beaten to death, but I just need a touch more travel and it should be in the sweet spot.
I'd think the single disk ACT would be good on the street. It holds 700+ ft lbs and is organic so it should be smooth, but I'm sure it has a little more pressure plate to make the organic disk hold. I have used ACT clutches in other cars, but not a vette so my experiance with them is not directly related. People seem to love the new ACT twin disk clutches for LS1's though.

I guess its all in ones opinion but I think the Spec 3 is a very smooth engaging clutch and is very streetable. The pedal does get a bit heavier and once you install the Tick Master it will get a bit more heavier but nothing thats an issue.

It's hit or miss. If it's not broken in it will be a little rough since the high spots take all the pressure plate load. If the pads are making full contact it shouldn't be that bad. From what I've see the pads on these puck disks are pretty much the same material so they shouldn't be that much different.
