New clutch very noisy
My new clutch, a Monster LT-1 is very noisy, sounds like it is growling. I think there is not any pre-load on the throw out bearing causing the noise. At a stop if the clutch pedal is pushed in, in gear or not, it is very quiet. At a stop, out of gear, clutch pedal out it is very loud. I have never been one to just keep the clutch pedal pushed in at stop lights. Not because of the effort but because of wear on the throw out bearing. I am curious though how much or often I can sit at lights with the clutch pedal engaged how long that bearing will last? Also where and how much do you shim the throw out bearing to quiet it down but not have any slip? I have seen some people had a spacer between the crankshaft and flywheel and I wonder if that is what it was for. My clutch did not have that spacer. My factory clutch did have a slight growl before but it is much worse now.

Step 1: stop listening to the people above.
Step 2: Get used to the noise because this is absolutely normal for every single Twin Disk clutch available for the C5, C6, or C7. If someone says it's not normal, its because they're ignorant.
Source: I've tried all of them.

Measuring the clutch travel is already part of the installation instructions for all the clutches I've put in (3 Mcleods, 2 Mantics, 1 monster, 1 Dyad, and 1 SPEC, if you're curious, all twins).
What you're missing is that the rattle noise he's talking about isn't coming from the clutch plate, it's coming from the transmission input shaft.

What should the bearing clearance be? If it is coming from transmission input shaft, it does sound like its coming from there outside of car. What can be done for that? I did also replace the torque tube bearings an rubber couplers.

When your foot is off the clutch, the clutch is solid - one piece. There's no noise it can be making. The torque tube shaft is spinning the transmission in neutral with a completely different harmonic.
The throw out bearing measurement is to make sure you're not overextending or preloading your slave cylinder. If there is no "dead zone" with no pedal pressure, you're not too far away from the forks. And if you were preloading the slave, you wouldn't be getting the rattle in a can sound, because there would be force against the pressure plate if it wasn't making noise (just like what you're doing by putting your clutch pedal down at stop lights)

I dont know how to post a video, sorry I suck. When I replaced my clutch I noticed wear in the end of pilot shaft an the pilot bearing was bad. I replaced both with new an since the torque tube was apart I replaced all the bearings an rubber couplers. They all seemed in excellent condition but at 55k miles I replaced them all. This is a video of someone else but the sound is exactly the same. you can hear him engaging clutch and sound going away. My cam idle seems to make it worse. As I read all the comments it seems the issue was never figured out for this guy either. https://www.youtube.com/watch?v=u_3DQSng0PM

Did you get the super light flywheel option or is it a heavy steel one. It is a little louder than normal. The lighter the flywheel clutch combo the louder it will be. I noticed over time the noise seem to subside as clutch broke in.
