Clutch kits are listed as “diaphragm” and “flat diaphragm.” Will either one work and is one better than the other?
A diaphragm clutch is a clutch that uses a diaphragm or Belleville spring, as opposed to a finger and coil spring design. The end of the fingers of a flat diaphragm have a flat spot. A flat diaphragm clutch will have slightly less travel and slightly more foot pressure. If you go with a flat, you’ll need a taller throw out bearing to maintain total stack height. Unless you’re trying to build a drag racer, personally I’d stick with same style clutch as you have now; whatever that is.
