  • Clutch friction surfaces

    Has any one used a full ceramic clutch v. Dual friction set up. What are the pros and cons

  • #2
    Yes

    Dual friction: pros: supposedly less chatter, cons not going to hold quite the same

    Cerametallic both sides: pros more holding power, cons: supposedly more chatter

    Full metallic, same trend


    I had no complaints about any of them, full metallic was a bit quick I guess, but I wont bother with anything less than full cerametallic any more.

      Organically wear much faster, and clutch service limits are dictated on total wear. So dual friction seems almost like the worst of both worlds. Still quick engagement with high wear rate (dominated by one disk). In fact, having 2 organics heats thing up less probably, so maybe longer service life with the same usage.

        dual friction setups have the ability to hold more power with less pedal feel, by design. That's why big hp setups in supercharged/turbocharged V8s go to twin or multi-disk McLeod setups. I had a twin disk Mcleod on my Kenne Bell supercharged mustang cobra. For my built SR20, I have a triple Exedy, which will easily handle the hp I am going to through at it.

        Surface material is a different argument.

          I think the OP is talking about mixing friction materials, either on the same disk or multiple disks. Same downsides apply to both.

            Im getting a new clutch for the ls the guy was telling me he had a full race ceramic clutch but he said it was kind of like an on and off switch, and then he had a dual friction disk which i want to say was ceramic on one side of the disk and carbon kevlar on the other

              Yea, that's what we've been talking about. It really doesn't soften engagement all that much because as soon as the ceramic gets some load its going to grab. And the wear rate of the softer bit will dominate overall wear and life.

              Kevlar isn't a great clutch material IMO, as its easy to glaze it with heat. In light usage organic is nicer to drive, so might as well use organic.
