The only clutch that I have driven was ACT clutch when I was stage 2. I drove Mike's car sometimes with his JWT clutch(I think its recommended for stage3). Comparing this clutch to those two the engagement point is probably similar to the jwt clutch. Its a lot like stock with the exception of some vibrations fromt he tranny/clutch since the design doesn't use springs to absorb them. The design is very similar to OS Giken clutch but with carbon material out the wazoo.
Hope that helped to answer your question. Sorry I'm a little wasted right now :-P.
