'78 through 81 (I think) got 917-derived brakes with floating front rotors, hat and separate spacers. After that, front rotors were fixed (and spacer offset incorporated into the rotor hub). These are "930" brakes; biggest brakes you can fit under 15" wheels and a massive upgrade to 911 brakes in terms of thermal capacity.
Brakes on 2.7 911's and SCs just aren't in the same league; (thinner rotors than 3.2's). Early 930's got the same brakes as the 911 of the same MY (although supposedly the alloy "S", rather than steel, calipers - which, ironically, I've read don't handle overheating as well as the steel). '77 up all got a brake servo, but not on earlier cars.
Brakes on a stock, pre-78 930 are generally considered - *cough* - not well matched to the performance of the car; "chocolate" refers to a propensity to overheat.
Brakes and intercooler are perfect examples of significant functional upgrades for early 930's - very desirable if you drive the car, right up there with junking US-spec thermal reactors that both strangle and prematurely damage the motor, or fitting a turbo designed for a 3 litre gas sports car rather than a 20 litre diesel truck (or whatever the heck the 3DLZ was actually built for).
But there goes originality out of the window.
