What I've found:
-All the setups use a 324x30mm brake rotor.
-R34 GT-R, 350Z Track and G35 Sport are identical. Calipers, rotors, and all hardware. The fronts will fit if you enlarge the mounting holes; the rears require custom brackets and work.
-The R33 is the same pad/rotor as above; the caliper, however, has the proper holes for mounting on an S-chassis. Front and rear calipers are a direct fit.
-One GTR owner I'm talking to says the rotors for the R32 V-Spec setup are different, but can't pin down how. He is unsure. Pads fit, and I'm assuming the caliper is the same.
What I need:
-What brake lines do I use? Presumably I just need 300ZX conversion lines to get a standard fitting instead of the "banjo" type that the 240sx stock brakes use.
-What e-brake assembly do I use? Can I use a 300ZX drum (aren't they all the same as the skyline ones?)?
-Are R32 GT-R Vspec rears the same as R33 GTR rear calipers? In other words, do they bolt right up as well?
-For the rear Z32 ebrake, S14 owners use R33 GT-S (non GTR) lines (or Yanack ones, which are the same thing). For S13, use modded Z32 lines. If I need a skyline e-brake assembly, do I (s14) still use the R33 lines?

OK... First consider the fact that the R32 GTR had Sumitumo Calipers (Not Brembo) and the R32 GTR V-spec had Brembo. Using that as a comparison the overall Size is only slightly larger and the fitment is the exact same.
I have R32 GTR Sumitumo Calipers on my S14... for the Front Calipers I had to use Z32 Hardlines off the Calipers to meet the Z32 SS Lines. I also have the original R32 GTR Hardlines but they dont match the Caliper... they honestly may be for the Brembos, and not the Sumitumo.
The Rear is Z32 Completly... but not the Subframe. E-brake lines were off a Z32 2-seater so they are too short to use (safely IMO). I will be getting the Yanack lines soon. The Rear setup for the GTRs have changed very little from each model. You guys can also consider that the Rear Sub-frame on the Silvia, Z32, and Skylines all mount the same and can be swap around like a Honda B-series. The S14 is about 10mm wider than the S13. The S15 I think is the same as the S14. Skylines are wider and I think the R34 is the widest. However regardless of the Track widening stance, some of the Arms are the exact same (S14 RUCA = R34 RUCA)... sorry got off track with that!!
Brembo uses a Standard size Caliper that is easy to use... The Z33/ G35, Skyline, Evo, STi, etc... use basically the same size Caliper the Mounting bracket is mounted to the botom of the Caliper... you can call and order the correct mounting bracket from Brembo.
You may get lucky and find a set of Skyline Brembo in the US from and Engine Importer (Venus-Auto, Jarco Inc) however, I doubt they will be left on the car as they sell used ones for nearly original cost in Japan.
