I really didnt want to start a new thread as i thought there allready was one on them.
I need to know all the differences between the 4 spot nissan callipers.
Z32 , Z33?
R32 , GTS, GTR
R33, GTSt , GTR

dave, might be a question well worth asking on SAU or searching on there matey : alot of work done with different brake upgrades on SAU.

R33 296x30 caliper
R32 296x30 caliper
R32 280x30 caliper
Z32 280x30 caliper
R32 280x26 caliper
Z32 280x26 caliper
Z32 280x30 caliper

there r different calipers even on the same model. z32 (not sure about the others) came in iron & alloy as well.

R33 GTS 296x30 caliper
R32 GT-R 296x32 caliper
R32 GTS 280x30 caliper = Z32 turbo 280x30 caliper (same)
Z32 non-turbo 280x26 caliper

Need to add what models they are to distinguish them. Any reason why you had two Z32 280x30 caliper, and i am also pretty sure the R32 never had a 26mm wide disc EDIT- yes they did (non GT-R 4WD version).

Like i said in your wanted thread, have a look at the DBA product list as it will list all the dimensions and different models.

EDIT: full list attached
Looks like all rears are the same (unless running Brembos)

NOTE: even though the R33 and R34 GT-R run Bermbos and their discs match, the mounting points do not. R33 is 12mm and R34 is 14mm.

I know there is a thread here about them somewhere, even included measurements (also had calipers like RX7, Celica 2&4 pistons) and pics to identify the differences. All the ones quoted above are all alloy, and you can get steel calipers from S14/15 silvias, to suit 280x30 size.

Ah this will do i think.

Z32 calipers are pretty much the same as their R32 counterparts, but also come in cast iron. 200SX's have the cast iron calipers too.
