    your clutch or your pressure plate and even both may cause you to slip.

    Centerforce are by far the best clutches I have ever driven (some people don't like them for some reason though :confused: )

    having installed a bunch in the short thirteen years I've done this work,my honest opinion would be buy a luk kit.it's all new parts and a little less expensive than the centerforce,and you will be able to push the clutch pedal in without using both feet. :p:

    I used centerforce or LUK in all my replacments job (about 8 I can count). Never a problem with either of these brands. Whatever you do, do not buy a remanufactured clutch (what most parts stores sell). Buy only a brand new clutch, and buy a whole kit (plate, disc, bearing). Luk can be found at www.dialclutch.com , centerforce at various online racing places (summit, jegs..the like). Also make sure to have your flywheel resurfaced, and do not got below minumum thickness (usally embosed into the egde of the flywheel). If it's got too many hot spots or needs to go below min. thickness to get it smooth, replace it. You can find them at various places for $100 or so, it sucks, but it sucks worse to put everything together and it still chatters or slips.

    if your looking to save money go with the luk, the centerforce is the same thing but a little more expensive becasue of the name on it...Also if you look closely at the centerforce clutch you will see "luk" stamped right on it...some people don't realize this....

    Also the aftermarket flywheels that I have seen, and some originals,
    don't have min. thickness stamped into them, like brake rotors
    maybe it is not an important saftey issue ?
    please comment if you can
