Does anyone know the specs/sizes of the 944, 951 and/or the 993 M/C bores? I'd presume 964 probably also used them? And perhaps the RS variants used interesting ratios?

Yes, my brakes are too front-biased for optimal balance, but I'd like to keep the servo/avoid fitting the twin M/C setup
The 993 uses a Lucas 23.8mm on vacuum boosted or 25.4mm or different 23.8mm on electro hyd boosted systems, none are compatible w/ the 911 boosters, and none are stepped
964 used 20.64 on vacuum boosted systems and 25.4 like the 993 on electro-hid boosted systems, again none are stepped.
