    Default clutch pressure plate help/ideas/questions

    Alrighty, i had installed a exedy clutch about a year ago, and recently it started slipping, not cool. So i go to replace my clutch disc today figuring that my daily driving and drifting have worn the disc.

    After finally getting everything out, i discover that the clutch has grooved the pressure plate (and flywheel, but the flywheel surface is repleaceable= no problem).

    But now im on the hunt for a pressure plate for the ACT 4 puck disc, and i have some questions.

    Do i NEED to go with a high pressure plate? Im thinking that because the force of the clutch is only focused on 4 smaller areas that a normal pressure plate would be ok.

    Would the racing beat street/strip work OK with my car being boosted (6 psi JRSC)??

    Does anyone know where to get a replacement p. plate?The only ones i can find are ACT, and they're a bit pricy

    thanks!

    clutchnet.com

    competitionclutch.com

    they both sell PRESSURE plates but youll have to call Competition to get a price.

    you dont make enough power to run an upgraded PP, just get a strong kevlar UNSPRUNG disk an youll have all the grabbing force you need

    thanks mike , but i already have a 4 puck sprung clutch disk. i'm pretty sure that it ll work ok , but i wanted to get some opinions on using a perfomance clutch with a regular pressure plate.

    i emailed competition clutch about a p. plate.

    Really? Even with all the crazy driving i have done has never broken a spring *knocks on wood*

    Well, i wont mind a lighter feeling pedal, as long as it grabs properly, i dont care how the pedal feels.

    Is it possable to machine the face of a p. plate?? Just curious....

    I've torn the steel where the spring mounts after installing the helical LSD...Clutchmaster Stage III disc with matching pressure plate. The disc was too harsh anyways so I went with an ACT street disc and kept the stage III pressure plate, by far the best setup i've ever driven (for a lightweight "low" power FWD anyways)

    As for the RWD, i know droptopdrifter can adapt to any setup...driveability shouldn't be an issue, he just needs one that will hold up to what he does. I would honestly go with a better disc and stronger pressure plate, why have one that is always going to be stressed and pushed to its limits?
