Hi Carl, When I installed a 3.6 varioram motor into my 1975 911S, it already had a Centerforce clutch and pressure plate with a Patrick Motorsport lightweight billet flywheel. Recently, while rebuilding the 915 trans, we noticed the clutch was wearing and should be replaced while in there. The centerforce clutch has a Sachs logo on it and looks like a Sachs except the Centerforce has cutouts alternating around the perimeter of the disk surface. Upon inquiring about purchasing a new clutch disk, they would not sell it to us without a new pressure plate too-cost for both $1000.00+. We went with the stock Sachs disk and used the old Centerforce pressure plate. No discernible difference, no slippage, in a car with 300 hp and 2325 lbs. My mechnic pointed out that unless I needed the orange color and Centerforce sticker, I'd do fine with Sachs, which I did.
