[Coupe50h]

I have a kk clutch and pp, last night at the track i went 13.0@ 105 with a slipping clutch, i was launching at 5k, wich im sure hurt this clutch, i hot lapped it and went 13.0 104, then 13.3 103, my 60's were not good as i had in the past, best i did was 1.86 then they got worse.
I could tell something was wrong, well today i get in my car and drive down the street, in 4th gear at a low speed, i can push the gas, and the rpms will jump around?
Now my question is, i have an old motorsport disc laying around, it still has lots of life left on it, i took it out for my t-5 rebuild with low miles, but could i just throw that in, and of course resurface the flywheel first? or will the pp have a different wear pattern, and chatter? because I would rather keep the kk pp if ya know what i mean, the hd motorsports are hard to push in.
I dont have the cash for a df setup right now.....whaddaya think guys? thanx.
