Manual Transmission - Anyone using a ram clutch with ram slave and master cylinders??

also i am going to resuface my spec 3 billet flywheel do i need a shim for my new ram hd that holds up to 600 hp?? and did you use ram master or slave cylinders or both? and how do you like it??

I used a new GM master/slave,Billet fly and no shims.Engage/dissengage point is perfect.It takes some getting used to and is somewhat of an on/off clutch and alittle stiff but not objectionable for an enthusiast.It was stellar for 80 miles then chattered for a few hundred more but after that its great.Holds awesome and bangs hard on gearchanges.
