Hi, I have a 1302 that I am going to use the early 944 1985 single piston setup on. However I choose to use the front calipers on the rear also. So I will have all four wheels stopping with front calipers. Can you suggest a MC for me. I also have a 1971 Porsche book where the front calipers and rear are very close in sizing. I believe I need more than 19mm mc.
