I am not that well versed on the various Porsche braking systems. I have just sold my Golf MK2 Race car, that ran 239mm discs on the front with single pot calipers, anything will be better than that!!
Given your stated desire to include

Porsche ‘Big Red’ brakes with drilled disks
the best course is to use either 993 vacuum booster and m/c or the 964C4 electro- hydraulic boost system, either allows the use of a 23.8mm m/c which is the minimum size for RS brakes, the electro hyd system further allows for a 25.4mm m/c which is even better.

To use Big Reds on a 964 it is best to use as many 993 parts as possible,
if you use 993 strutsand 993 uprights(or better 993RS uprights) then 993 Big Red calipers and rotors are a straight bolt on. There is also a black version which will match the black 993 rear calipers that you need to use w/ the Big fronts. To use the 993 uprights you will need to use 993 tie rods, 993RS uprights will require the use of 993RS or GT2 evo tierods. But all the 964 stuff is a straight bolt on

In back use 993 rear calipers and stock 964 rotors or if you want drilled 951 M030 rear rotors
