my old car:

FULL R33 GTR brembo's front and rear with s14 5 lug conversion.
-dba r33 gtr rotors, hawk hps pads, spl brake lines
-complete and total bolt-on using r33 caliper bolts to s14 front spindle and z32 rear spindle. the only caveat is the r33 caliper bolts are too long so i spaced them correctly with a stack of 3 matching sized washers. or you could cut the r33 bolts shorter.

your best bet for aftermarket rotors is DBA (disc brake australia). check out their website for fitment/rotor size differences. their data is accurate and you can see that there is indeed a difference between z32, z33, and gtr rotor size/thickness.

for reference i originally tried to fit a 30mm aluminum z32 caliper with JSK brackets to my s14 spindles using the r33 gtr rotor. it did not work. the hat offset is different between r33 gtr and z33 rotors even though they are the same diameter and thickness size. if you buy aftermarket make sure you get the right rotor for your application.

optionzero has made some valid points that you should hinder. the best (and easiest) solution for matching rear brembos is a gtr setup, being r32 gtr vspec2/r33 gtr/r34 gtr specifically.

yes a z32 rotor would "work" in the rear with an sti caliper however it is technically undersized and would oversweep the rotor just as a z32 caliper with bracket would not fully sweep a z33 track rotor.

it's your car and just something to think about. the best OEM bolt on option for your 240 is a true skyline gtr brembo setup. however a full z32 setup with good pads/tires is probably as much stopping power as your 240 ever needs.
