How many go the whole 500 or more? I went 375 before going wide open. This is a mcleod rst. Did a bunch of stop and go.

 

In reality...it should need none.

It's a mere formality to allow some bedding in of the surfaces.

I guess you could compare it to someone claiming your brakes need bedded in for 500 miles before using them....wouldnt really be practical for a race car. Nor would bedding in a clutch for 500 miles on drag race only car.

Just dont slip the ***** out of it, give it some fair usage and it will be fine.

And if you're nowhere near the capacity limit of the clutch, I wouldnt worry one bit.

 

I didnt do the proper break in on my monster stage 2. I took it easy for a little bit, maybe 150 miles or so. No chatter or any issues, works just how it should.

 

Clutch manufactures generally state 500 mi break in consisting of "normal city driving" so the clutch disc material can bed with the FW, PP & floater plate (if multi disc clutch).

Basically you don't want to slip a new clutch as the disc will glaze and the clutch will not work well after that

IMHO I think 500 mi is a bit excessive but the clutch companies are just covering their *** against warranty replacements

Basically just like new brakes you don't want to slam them when new. Let them go through a few heat cycles so the friction material can bed with the hard surface (rotor)

Race cars use ceramic or iron composite disc and change the clutch discs often

 

The whole purpose of the 500 miles...IS to slip the clutch a lot ( without undue heat of course ) to allow the components to bed into each other.

 

Right, you do want to build up a small amount of heat and SLOWLY wear all of the friction surfaces into each other evenly.

What you don't want to do is throw a brand new clutch in and do WOT dyno pulls on its first mile of life because it will either be severely compromised, or fail completely.

 

I put my diamond stage 2 on the dyno after about 100 miles. Was a little worried but still grabs like a champ 4 years later.
