A vintage 11" Schiefer pressure plate should be good to about 600hp. About 2800# Long design. They have short counterweights that clear inside the bellhousing. I've been using the pressure plates with aluminium internals that have a hardfaced metallic coating. Try to mate it with a 100% organic disc. These discs are slightly lighter than the metallic combo discs and are easier on the transaxle synchros. Pressure plate is Schiefer part # 625-0054 or 625-0057 vintage 1980's and 1990's. I've been saving a couple of NOS ones if you interested. They also work well with a litewight aluminium flywheel, but watch out for the balance (if original external) on the liteweight flywheel. Pressure plates are neutral balance.
