R33 GTS-T. **** all in the way of ridges bar a bit of a raised section.
I was agreeing with you. Somebody else said they had "cooling fins", which they don't.
Right here you go. It took about 10 minutes so not the hardest thing in the world to sort out.
B15 : 305mm x 26mm (4 pot brembo caliper)

Z32 NA : 280mm x 26mm (4 pot ali sumitomo caliper)
Z32 TT : 280mm x 30mm (4 pot ali sumitomo caliper)
(There are 2 types, 26mm and 30mm both are aluminium, look similar, from what I've found teh 26mm has the number 1 stamped into the casting and the 30mm has 2 stamped in)

The ones pictured are the newer type. From what I've found they're the very same except the older ones only had Brembo written on them. The newer ones have Nissan and Brembo.

Missing calipers.
R32 GTR V-Spec: 324mm x 32mm (4 pot brembo caliper) for reference look the same as R33 GTR.
I'm confused now... my R32 GTR calipers arrived today, and I thought they were supposed to be iron calipers but they seem lighter than my S14 calipers and are immaculate, ie. no rust and look very new. I'm going to fetch one to compare it to these...
And that awesome post a bit above this should be made a sticky.... well done that man, Muttly!
No problem. Glad I could help.
X2 for a thread tidy and sticky :nod:
Any chance of moving my post to first as I've just updated it. I've a bit more info to put in as well as I've found special edeition z34's and I was going to try and suss out the rears at some point.
Thanks! I'll give a shout when I've an update for it.
Might be asking a silly question, what dimensions have been provided for each caliper? They sound like disc sizes. But I have Brembo Calipers and random discs so I'm not sure exactly.
Supposedly these are R33 GTR V Spec Brembo's: - They are original black, I'm not sure on the ruling of GTR's running Black vs. Gold Brembo's though.

Piston sizes - approx.
Small piston: Inner 22.1mm Outer 34.5mm
Large piston: Inner 26.7mm Outer 40.5mm
And these are the disc Dimensions I have:
300mm(Disc Diameter) x 30mm (Disc contact surface thickness) - Black Diamond. Smooth (no grooves/drilled holes/dimples)
300mm(Disc Diameter) x 30mm (Disc contact surface thickness) - Unknown brand. Anodised Centre (bell?). Cheap ebay specials or high performance stuff? Pictured below:

Any thoughts are welcomed.
The black and hold only mean
Black : R32 V-Spec / R33
Gold: R34 / Z33
Technically there's no real difference until you get in to late R34's and all Z33's. they have different mounting hole sizes.
Piston size is irrelevant.
The discs you have are wrong. They need to be 324x32.
So these black would be R32 GTR VS or R33 GTR. They were marked as V Spec R33. But I see no difference in the calipers to say yes or no.
Discs. Odd that the used discs pictured, were fitted, with these calipers and EBC Yellowstuff pads. I don't know if they were fitted to an S body or an R body though. Surely the discs fit in conjuction with the calipers, but possibly not for my S body mounting needs. Aside from that, I potentially therefore have 2 sets of discs I have no use for if I have to incerease by 24mm Diameter and increase by 2mm width. It's just odd that these were run on a car so not sur why they won't fit. Next question is, who wants to trade discs lol
I'd fit them to trial it and just to see what the story is, but I don't want to drill my hubs and realise it's a long wait for correct replacement discs and not be able to fit my old calipers back on. If these are R33 GTR calipers, then I shouldnt have to drill the hubs. I can bolt straight on I believe. However there are afew forum posts saying 324x30 and some saying 324x32.
All R33 GTRs use the same brakes. No exceptions.
You can run smaller discs with no issue but you just won't be using the full capacity of braking force that's available. At 1" smaller than standard you'd be losing a huge amount of force.
You'll wear the pads to a point of stress that they could fracture if a stone was to get in the wrong place.
The disc size is determined by a combination of hub and caliper. However all S bodies and R bodies use the same hub dimensions (with the exception of late R34's but even these are the same main dimensions just the bolt holes are a different size) therefore the disc will be the same size regardless of application.
Ok excellent mate. Thank you.
Correction above. I took the label on one disc as a given. It said 300mm. Measuring BOTH disc pairs I have, they are in fact 324x30mm.
My calipers do not require drilling, but do require a different thread bolt. Looks like M12x1.5. Not sure exactly. Getting it in place (without pads) it looks like the discs are central but even at 30mm rather than 32mm it's close to the caliper.

30mm will be fine. The extra 2mm won't make that much difference. Just don't let your pads go all the way down.
