Clutch Break In Question

[kannon]

apparently the CM stage 3 has some kevlar in there according to the enclosed note, which is why it requires a break-in.

[Holden]

Mine is a CS Stage 2. I figure the break in period is to gently wear the clutch surface down and eliminate it's irregularites. Perhaps if you wail on a part-organic clutch too early, you'll tear away larger chunks, which will leave less clutch material for the future.

This idea would explain why race clutches have no break in.

This is really pissing me off! I have a new LSD and am back to 10psi and I can't enjoy either!

Oh well. I'm going to floor it enough to tune FP and ignition for 10psi. Come this Friday, I'll consider the clutch broken in, no matter how many miles I have on it.

I just called clutchmasters regarding the 500 mile break-in period on my stage 3 clutch.

I asked them to go into a little more detail about what it does, and how to measure 500 miles of stop and go driving.

Im not fully satisfied with the answer I got, but here is the jist of it:

He said just to do 500 miles of regular driving. Similar to what you would do if you bought a brand new car. Dont romp on it. He said to keep it under 4000 rpms (although he didnt ask what kind of car i had).

He also said it would allow the clutch, flywheel, and pressure plate to all mesh together well.

Thoughts?

I agree w/ the 500 mile theory, better safe than sorry, I just ordered my CS stage 2 clutch, looks like I got some drivrn to do.

I got my CM stage 3 from Endyn today:

"IMPORTANT Kevlar break in period. Clutchmasters kevlar clutches require a break in period of 450-500 MILES of stop and go driving before full abuse can be initiated. (No full throttle shifting or compression braking) This Milage "(their type not mine)" is required to allow the disc to properly seat to the flywheel and pressure plate."

What the hell is compression braking? Is that braking with the clutch?
