Recently installed a 3 finger Zoom. Didn't last one hard pull through 4 gears in a customers car. We installed a McLoud diapragm. Its been in for 2 years . The car just came back for Quarters and trunk floor. Clutch still works great and second set of tires .
The diaphragm style pressure plates have come a LONG way from way back when. Used to be, the only thing good for a high performance build was the three finger Borg and Beck, but a good diaphragm style is right on par with them now.
