You would be better of selling your brakes Pete and grabbing some R33 calipers, the brackets work a little better with a bit more meat in it.

Thats said, be interesting to see how the GTT caliper stradles a 343mm rotor.

If someone is looking for these for an R32 or Z33/S14/15 then i am selling mine at the moment. I have finally manned up and grabbed some rotors and calipers that will likely rub on my rims :D

I am not sure that I understand what the fuss is all about with changing rotor diameters and the effect that has on the pad shape. Sure the inside and outside radius of the pad will be ever so slightly different to the inside and outside radius of the rotor. But is it such a big deal?

The first picture Roy posted shows that he could have used a 2 mm larger diameter rotor with those pads. Noting that there is not really much of a problem with the different radii.

If you are currently using a 280 mm rotor (R32GTST) then you could be using pads shaped for a 280 mm rotor or a 296 mm rotor. There are far more compounds available for R32GTR’s, hence 296 mm rotor. So if you buy GTR pads for your GTST (with its new 324 mm rotors) you are only talking about a 28 mm increase in diameter from where those pads are designed for.

Hardly a big deal, since the same pads work OK on 280 mm versus 296 mm ie; a 16 mm difference.

The next step up would be to use the R34GTT pad which, being designed for a 310 mm rotor, would just about fit perfectly on a 324 mm rotor. I haven’t actual tried R34GTT pads in an R32 (GTST or GTR) calliper. But that could be the answer, to what is not really a big deal anyway.

:( Cheers :)

Whenever I've bought pads for my GTT people tell me the R33 GTST ones are the same and that's what I've been using.

I used the Unique Autosports calliper extenders and brake scoops on the R33GTST for the recent SAU day at Wakefield with DBA 324 mm 5000 series rotors, Nismo braided hoses, Castrol Response Super Dot 4 Brake fluid and Bendix Ultimate pads. No problems locking the brakes on demand using Yokohama R tyres even after 2 consecutive 15 minutes sessions. No fade, no shudder, no problems on the day or since.

I will post up some pictures of the installation process and the finished result when I get a chance.

:ermm: cheers :)

Sydneykid, in your post above you mentioned about providing info about fitting 324mm discs and calliper adapters to a 33gtst.

Having had a thorough search I didn't uncover any information about this.

Did you post anything up? If not is there any chance of you being able to?

Looking at the most cost effective way of increasing the braking effectiveness on my car, currently running r32 gtr brakes.

Thanks.

James.

Hi James, just before the SAU NSW track day at Wakefield Park last year I fitted some UAS calliper adpators, brake scoops and 324mm DBA 5000 series rotors to the R33GTST. I have a number of pictures and quite a few tips on fitting, but my gallery is full, so I can't post them at the moment. I either need to ask for an increase in my gallery size or find out how delete some images.

Cheers

Gary

    • Bit of a pity we don't have good images of the back/front of the PCB ~ that said, I found a YT vid of a teardown to replace dicky clock switches, and got enough of a glimpse to realize this PCB is the front-end to a connected to what I'll call PCBA, and as such this is all digital on this PCB..ergo, battery voltage probably doesn't make an appearance here ; that is, I'd expect them to do something on PCBA wrt power conditioning for the adjustment/display/switch PCB.... ....given what's transpired..ie; some permutation of 12vdc on a 5vdc with or without correct polarity...would explain why the zener said "no" and exploded. The transistor Q5 (M33) is likely to be a digital switching transistor...that is, package has builtin bias resistors to ensure it saturates as soon as base threshold voltage is reached (minimal rise/fall time)....and wrt the question 'what else could've fried?' ....well, I know there's an MCU on this board (display, I/O at a guess), and you hope they isolated it from this scenario...I got my crayons out, it looks a bit like this...   ...not a lot to see, or rather, everything you'd like to see disappears down a via to the other side...base drive for the transistor comes from somewhere else, what this transistor is switching is somewhere else...but the zener circuit is exclusive to all this ~ it's providing a set voltage (current limited by the 1K3 resistor R19)...and disappears somewhere else down the via I marked V out ; if the errant voltage 'jumped' the diode in the millisecond before it exploded, whatever that V out via feeds may have seen a spike... ....I'll just imagine that Q5 was switched off at the time, thus no damage should've been done....but whatever that zener feeds has to be checked... HTH
    • I think Fitmit had some, have a look on there (theyre Australian as well)
    • Hah, fair enough! But if you learn with this one you can drive any other OEM manual. No modern luxury features like auto rev-matching or hillstart assist to give you a false sense of confidence. And a heavy car with not that much torque so it stalls easily. 
    • Actually, I'd say all three are the automatic option. Just the different trim levels. The manual would be RSFS, no?
