Default Clutch Break In

Tried Searching, but didn't see any results. Can someone please chime in on the suggested way to break in a new aftermarket clutch and flywheel? I assume no launching, but anything else I should do/not do?

The ORC manual stated that you should just drive normally for 500km.

I keep the rpms low for shifting for the first 1000 miles and no high rpm down shifts.

Don't know about aftermarket. But when i had my stock clutch and flywheel replaced under warranty, it slipped a bit and smelled for the first few hundred miles. After that it was good to go! Just take it easy for a while.

Drive normally for 500 miles while avoiding any high rpm clutch drops or shifts. The point of a break in is to seat the surfaces while avoiding any glazing. High heat generated from high rpm shifts can glaze the clutch and ruin its lifespan.

The new surface of the clutch plate needs to be broken in so i would definately recommend the standard 500 mile break in.

I was told 400-500 stop-n-go miles.

This article came up in a Google search, last question:

T: Why is clutch break-in so important?
S: We recommend 200 to 300 miles of mellow usage for our street discs. The purpose of breaking in a clutch is to engage the disc in a controlled, consistent manner to ensure the disc, pressure plate and flywheel all make full surface contact. It's also a chance for the friction material to experience normal heat cycles.
