Hey guys, I just replaced my 6 puck ebay clutch with a much nicer ACT disc and RB PP and bearings. Now I need to know the proper method for breaking in a clutch. I just dont wanan kill it prematurely. I searched here and google and got zilch.

 

i think act recommends 300-500 miles of easy driving. no launches, keep the rpms down



For organic street discs "00 and SS" we recommend breaking in the clutch for 200-300 miles with mild engagement such as stop and go city driving prior to racing or spirited driving. ACT race discs usually only require a few hard slips to lap in the surfaces prior to normal driving or racing. Do not overheat the clutch during the break in period.

 

Is there a parallel to brake bedding with clutch breakin? It seems the same general concepts are at work. And, if that's the case, wouldn't heating the clutch up to the transfer temperature be a good way to break it in? I guess there's really no way to cool the clutch like you can brakes, though. Short of sitting in gear with the clutch in, you won't cool the clutch without getting uneven transfer.

The 6 puck can be slipped pretty hard a couple times, and it is good to go, mine holds 400+ftlbs out of the box. That break-in for the 6 puckis per ACT. Carl

 

WHat about a full faced disc?

 

i prefer not slipping the clutch to break them in, that can cause chatter issues with it later on. i prefer an easy break in for at least 100 miles which means no hard launches or excessive slipping on the clutch.

breaking in a clutch is completely different than breaking in brake rotors due to heat transfer and cooling differences.

 

usually the best way to "break in" something isnt to beat the hell out of it. use common sense.
