hey i am looking at getting a clutch and flywheel from ACT, i am looking at clutches and they have a 6 puck sprung clutch, a 6 puck solid clutch, and a 4 puck solid clutch, all of them seem to be almost the same price, is there a performance difference between any of these, which one is the best?

 

In general, the fewer "pucks" a disc has, the more torque it can handle. Engagement will also be harsher compared to a disc with more pucks or a one-piece facing. Sprung discs absorb some of the vibration/chatter associated with engagement/launching, which can make a given clutch more streetable on a daily basis, but a solid disc will be lighter and has less parts that can break. That said, the clamping force of the pressure plate will usually have more of an effect on drivability than whether or not the disc is sprung.

What are your goals and intended purpose for the car? Is it a daily driver, or will it primarily be seeing time at the track? I've never driven a sprung 6 puck clutch, but an unsprung 6 puck clutch with a single diaphragm pressure plate is very streetable once you get used to it. An unsprung 4 puck with a double diaphragm pressure plate might be a bit much to drive every day.

 

my goals for the car is to run about 400+ whp which wont be a daily driver but a street car for the most part, and still some track time. so you are saying the solid clutch is stronger and basically better than sprung?

 

Yes, a solid disc is stronger because it's one solid piece of metal. The absence of springs also means that you don't have to worry about them failing and rattling around inside your bell housing. Granted, spring failures are somewhat rare, but they do occur.
