I dont run porsche discs, but I do have golf discs all round, golf 1 rears and golf 2 fronts. Anyway, my master cylinder was too small. My mechanic, who designed the conversion, then installed a master cylinder from a VW bus. The later bus with the 2.3l 5-cyl audi engine. Dont know if you guys ever got those, but it was the newer version of the classic bus, with the engine still at the back and shaped like a brick.
