Boygenius - what size is your 911 master cylinder.
Comments have been made before that the 944 brakes work as a system and although they came off a front engined car using the single pot calipers with the 19mm VW MC makes it even more front biased. From memory the 911 MC has no variation in the front and rear diameters to make up for the ratio of the 944 fronts (huge 54mm) vs the rears (36mm).
Shad Laws made some comments in this thread that are very relevant to this discussion.
