I have always disliked the clutch that came with the car- Samson had installed an RPS stage 1 because of the lightweight flywheel (8lbs vs 24 stock) well here is what i have learned- and i may post this into a different thread so that others can search it.
My dislike with the RPS is chatter and fast wear- I replaced the clutch a year ago and now Nabil (First Class Automotive) is telling me its almost burned again even though i do not feel it slipping yet
the factory flywheel is 24lbs because its a dual-mass flywheel. meaning the flywheel itself is dampened with springs, so that the clutch disc is not. which is why the dang thing is 2" thick and costs $1700 for a flywheel.
I like the light weight of the RPS unit and how it revs but hate that chatter and shudder i get when i take off unless i ride the clutch which i refuse to do.
So i spoke with S.P.E.C clutches in Alabama (bear with me....... haha jk) they make a single mass disc for our cars (NA2) which weighs 15lbs. but then you must use a sprung disc (which is what most cars are anyway) the benefit of their clutch is that it is infinately variable... i.e. I can use their fly. with a factory press. plate and disc, or use any of their stages xx disc and pp mix and match. Although it can be done they do not recommend using a factory press. plate and disc with thier flywheel. because then there is no spring or dampening... remember their flywheel is not dampened and niether is the factory disc.
so my new tranny setup will be as follows:
SPEC 15lb flywheel
Factory Pressure plate (for easy pedal feel)
Stage 2+ sprung disc (made of Kevlar for less chatter than the stage 1 which is organic)
EVO- although i agree with your idea more on the NSX-R spline- getting into gearing and rebuilding a tranny requires someone you REALLY trust- I rebuilt the tranny on my integra (twice) the first time i didnt check the clearances 100% I did a good job dont get me wrong but something happened causing one of the bearings on the main shaft to go out and i had about 15 little steel balls rolling around in my tranny case---
which led to rebuild #2, on the teg that cost me about 200 bux------
the NSX-- not so much- i just would trust it to be done unless someone was gonna stand 150% behind their work.
so thats where i stand.
