I know 500 miles but is there a proper procedure?

Seriously though 500 miles will be tough on me.

 

i just "drove". but then i also just used oem w gt2 disc. nothing has changed engagement point wise or anything. just drive, and don't enter any hill climb events for the first cpl thou lol

 

I would expect with an aftermarket clutch if there was some specific break in the clutch manufacturer would have included something about this in the clutch kit paperwork/installation instructions, documentation.

AFAIK, for OE clutches there is no break in.

There is the the sensible caution to avoid excessive slipping for name your number of miles and 500 miles is good as any number.

This is because the clutch disc is so new its contact surface is less. As a result the limited surface contact area of the disc that makes contact with the pressure plate and flywheel will heat up more. This can lead to degradation of the disc or the pressure plate and flywheel due to extreme localized overheating. The disc can eliminate or the pressure plate/flywheel can develop hard spots.

But how many miles to allow for the clutch disc to obtain more complete contact with the pressure plate and flywheel? 500 miles? Who knows?

I do know what when my Turbo's clutch was exposed when a RMS was replaced the disc looked remarkably new with obviously less than 100% contact. The disc showed (by precision depth micrometer measurement) no wear and this was at over 100K miles. Theoretically the clutch break in period could extend to 100K miles or more.

So what to do? Just avoid excessive slipping of the clutch regardless if the clutch has 1 mile or 100,000 miles. And don't worry about any break in.

This is not to say I would set out to break the world record for 0 to 60mph elapsed time. With a new clutch I would take it a bit easy on the new clutch for some miles. Not so much as a break in but to get to know the clutch, and to give myself time to become comfortable the clutch will not manifest an early/premature failure. By taking it easy if the clutch does suffer from a premature failure the idea is to limit any collateral damage from this early failure.
