When people speak of better engagement with a puck clutch, what does that mean? Will a normal street disc slip a little as opposed to a puck disc grabbing immediately?

RPS stage 2 clutch will hold 600 hp with an OEM disc, whereas the stage 3 holds 700 hp with a puck disc. I know the puck one will be harder to drive and be all chattery, so what are the major advantages of it over an OEM disc? (for street/strip cars with less than 300 hp)

 

well usually the better disks are made of a better material that isnt as forgiving on the flywheel and dont last as long as a stock clutch. the actual clamping power is in the pressure plate. a good street setup is the ACT extreme pressure plate with street disk. the disk has brass fibers embedded in it to increase friction and resist burning as easily as a stock clutch. another difference in the disks is whether the hub has springs or not. an unsprung hub will grab immediately and sometime make for a little bit of a jerky take off in a street car. a sprung hub absorbs the initial grab of the disk making it engage smoother.

 

but, a sprung disc has it's downsides. If the spring breaks, or comes loose, it can also destroy the pressure plate and/or flywheel.

 

So I guess the question is what do U recommend on a turbocharged street/strip car?

 

I've only been in one car that had an unsprung hub but I didnt like it at all. I dont think I would ever get an unsprung hub for my Integra but I'm thinking about getting one for my Corolla.
