so i got a used hks twinplate while i was in japan from an upgarage. For as much as i payed for it, i figured even if it was shot, i could just buy a rebuild kit and still come out on top. anyways, i just pulled off the starter to pull the tranny off and noticed that i already have an aftermarket clutch in there. its yellow so im guessing ACT. the clutch doesnt slip, but i know that the hks is a hell of a lot better clutch than the ACT. my question is should i go ahead and put the hks in, or leave the unknown model of ACT clutch in there? also, im not sure of the condition of the hks. the disks dont look really bad, but i've been searching for the specs of new disks and cant find them. does anyone know the thickness they are supposed to be? or just the thickness of other clutch disks so that i could get a ballpark idea on them. any help or advice is much appreciated! thanks!

I'd guess by your mod list you should be fine if you current clutch doesnt slip.
