I think there are two different switches. The cruise control disengages at the slightest downward movement of the clutch pedal. The starter won't engage unless the pedal is fully depressed to the floor. That sounds like two different switches to me...

I was having problems with my S stalling out while decelerating with the clutch pedal pressed to the floor. Mechanics kept my car for a month before they noticed the crank was moving (toward the bumper) a good 2 - 3 mm. They said my thrust washers were either never installed or my crank ate through them. This was on a brand new engine w/less than 6k miles. My clutch setup was ACT pp w/ACT flywheel. Rest of the clutch setup was OEM.
I called Jeff @ Htguy and he replaced the block under warranty. Still running the same clutch setup. The shop said they thought my clutch wasn't lub'd properly causing the equivalent of crankwalk. Could it be my clutch setup that is causing this problem? Jeff @ Htguy said he hasn't had any problems w/his setup. Mechanics called ACT and they informed him that they don't recommend using ACT products with the S2K OEM setup.

That's a little concerning....
I just spent 2g's that could have went to other mod's instead of labor. And... If it is the ACT setup that is causing the problem, I might be in need of another block shortly. Jeff is a great guy to deal with so I am in no way bashing him. Heck, he sent out my short block immediately and answered all of my questions. But if there is a reliability issue with the ACT setup, why would he continue to market them? Maybe a few of these kits caused owners problems and "we" just hear the bad?

I just searched through some "old" threads concerning this but couldn't find anything negative toward ACT clutch setups; specifically Jeff's ACT/OEM setup. I researched his kit before I bought it last December and the good reviews definitely out-weighed the bad.. I'm going to call Jeff tommorrow and point him to this thread and get his opinion on the matter.
Maybe I'm just horrible at shifting which is leading to drivetrain damage!

The "kit" has been on the market in a few forms since Comptech came out with their flywheel years ago (I believe late 2001). Unfortunately, it takes a while before issues like this become readily apparent.
The ACT combo has become a very popular setup, and as FF2Skip stated, this just increases the likelyhood you'll see a problem because the sampling pool for this type of setup is that much larger. Given more time the failure rate goes up as well.
I think this issue has only just to come to light recently. However, it's a problem that's now being recognized by major players in the modification business, which makes it important to take notice.
I think there are several factors that can accelerate the problem: the harder you launch your car - especially if you dump the clutch, the more damage will be done (shock loading increases the effect); idling with the clutch pedal depressed further increases wear; starting with the clutch in can really produce a lot of wear; the type of oil you use may offset or accelerate wear - there are a lot of factors that may or may not contribute.

I don't think it's your shifting, unless you're really rough on the engagement (dumping the clutch). I think perhaps using the ACT setup with a new motor may have something to do with your situation - due to the fact there was more stress put on the motor during the break-in period. That's only a theory though.

I am very glad I wandered in here, something I don't do nearly as much as I used to. We're(InlinePRO and I) sadly pulling the 2.5L out of my car so that I can compete in the NASA TTC class. The 2.5L puts me on the cusp of TTA. Since we're not running any more technical traks, any high HP car has enough straight to make up for any cornering loss. 
I'm not happy about going back to stock hp(first time since '04), but I'll have to look further into the clutch situation. Rarely do I launch(I autox very little) and never leave the clutch in. I almost exclusively track the car now.
