Need Clutch Guru Help !

When I purchased this car I was told there was a new Center Force Clutch & PresPlate installed. The car had some Z-Bar linkage issues but I took care of that. But what I noticed most was, when half way power shifting the car did not have a significate power bang to it. It just eased it's way into gear. No way could you chirp the tires or bang the dash. I just figured it was worn or a bad Pressure plate. When I tore it down, it was indeed a Centerforce. It looked good, no hot spots, still plenty of coating left on the disc. The flywheel looked good also. No warpage or burn spots appeared to be smooth & level without any ridges.

A friend of mine had installed a new Zoom Borg & Beck design clutch in his car, drove it about 60 miles then tore the engine down. I purchased the unit from him. Now things are worse! It seems to slip worse and now I get chatter from it when I let the clutch out. I was later informed that this is a Kevlar coated disc and you have to drive this thing a couple hundred miles in order to break this thing in. Sorry but I'm from the old school and something doesn't seem right.

Can anyone shed some light or suggestions on this?

BTW, I've checked the TO bearing to make sure it's not hanging up on the spline cover, have adjusted the pedal to have about 1-2 inches of play before engaging and finally the car shifts just fine as long as you are driving it normal.
