pressure plate experts

Asking borg & beck style p.p. gurus. Ok Iive confirmed that rite @ about 2000-2500 rpm I can actually see the release fingers swing out & make contact with my release bearing! At idle its fine & I have the 1/ 12 free play in (dead space or take up) my clutch peadle until engine hits 2k on up you actually feel the free play go away! Its a scalloped 10 inch borg & beck from ram. I called them & hes stumped as well its a non assist type p.p. with no rollers or anything like that. The disc will release but has a slight 'pop' when it does due to fingers being flung out. Anyone have a clue what to look for as to why its doing this? Wouldn't that wear out a throw out bearing in no time? Any help is greatly appreciated!!
how thick is the disc?? that determines finger heights. if too thin, lets fingers come out. you have shims under pressure plate?
