Good feedback guys!
As for the 944 MC I got this one off a '87 944S model and it is cast into it "23" on one side and "20" on the other. Maybe this is different than the early 944 '83-'86 MCs?
So the 23 is really 23.81, Jess that really does throw the numbers a bit
Okay so the 19 or 20 will realy be either 19.05mm (12/16") or 20.64mm (13/16").
I went and measured the single piston 944 calipers (again from a 1987 944S) and I found them to be fairly spot on to the 54mm (53.975) front and 36mm (35.56) rear. Wally I am not sure why yours would be different in Europe?
Thanks,
