    Nope, they went to 240 mm in the CD009 change to help the synchros out.

    Here's a poorly formatted version:

      The CD009 are the later version. Hmmmmm

      So twin plate or something like a FX400 then?? There are not many options for single jingle. However, 400+ w torque is only for the couple of dyno hits. 250-300 w torque is the consistent target. Maybe just stick with my Comp Stage 4 and see how it holds up.

        Honestly, clutches have a safety factor on holding torque, because when you spin them at full clamp load they die very quickly.

        That said, a twin disk makes the trans shift like butter because the synchros have so little work to do.

        If you're really going to be belting out 400+ wtq, you might want to think about putting together a cerametallic Tilton twin disk setup. All the off the shelf twin disks from US mfg use metallic disks which will not last long on the street.

        Trying to do it in a streetable single disk is impossible IMO. It'll be some cerametallic gorilla clutch.

          Why bother if it would just be turned up on the dyno? Not trying to be a dick, just seems like you can get something that will work if you don't go for the max power.

            You have a build thread? I have no idea what your big picture setup looks like. Toss one up, keep nrr alive...

              Oh absolutely! I just picked up a twin disk for cheap and then it all spiraled down hill from there lol

              I am just going to run what I have and see what happens. The gearbox is actually pretty easy to drop if I have to do it in this chassis

                That's nice. Can't drop mine without lowering the entire front subframe with engine about 2 inches. Next time I have it out I need to clearance the tunnel.
