Well it still breaks in... more like bedding in, like brakes. The idea is that with usage the clutch disk conforms with the pressure plate and flywheel surfaces.Originally Posted by 86lance
I have heard a couple different ways to break in clutches. 500 miles is the text book answer, figuring that even if someone drives 500 miles on the highway that there would be enough shifting to bed it in. Now the difference is that most clutch manufacturers say to drive the car easy for a while, and then when I got my RPS clutch it said to drive it agresively.
I am not sure about ceramic but the sintered bronze puck clutches seem to break in pretty quick. The six-puck one currently in my Z went around the block a couple times, up and down shifting about every 3-4 houses, then got loaded on the trailer to go to the track. Couple easy (12 psi) runs on low boost running low 13's and then I turned it up and went 11's
Like I said, not sure about ceramic (but I would guess it is similar) but I would do exactly like TU recommends IF they warranty it.
