| Just googled randomly and found this info: The goal behind breaking in a clutch is different for a puck disc versus a street disc. Street disc - Break in helps lap the surfaces smooth and the wear rate decreases after break in. This has to be done over time (200-500 miles for instance) for best results. City driving is best and full throttle, high rpm, etc doesn't matter. What matters is that you don't allow the clutch to get hot from excessive slippage, so don't apply full throttle unless the clutch is fully engaged. If the clutch is ran hard right away, more material will wear off before it properly laps in. In this case, proper break in = longer clutch life. Puck disc - Break in allows the surfaces to get full contact by wearing off the high spots, etc. Once full contact has been achieved, the coefficient of friction is higher and it has more area to distribute the heat. It is not as important to break it in slowly, like the street disc. Some racers just slip the clutch several times pretty hard before taking it to the track. Since there is no real precise method for us to recommend doing this without damaging the clutch by going too far, it is far easier to just tell customers to put a couple hundred miles to break it in. In this case, proper break in = better performance I hope that clears things up a bit. If you have any further questions, feel free to contact me.

Advanced Clutch Technology Inc. Question: Quote: Some racers just slip the clutch several times pretty hard Can you further elaborate this? Like slip it as in not fully releasing the clutch while taking off? Answer: No I really can't elaborate for the reason stated earlier. An experienced racer should have a good feel for it, and that is what is required when trying to shorten the break-in procedure. As soon as I try to explain in more detail, then someone is going to screw it up by overheating the clutch and potentially destroying it. Then I get nasty messages telling me that I told them to do it that way, etc...
