The only difference between the R32 GTR & R32 GTS-T Brakes is the size of the front rotors. GTR being slightly larger :D

The R33 GTS-T has the same size front rotors as the R32GTR.

A set of R33 GTS-T Front rotors & calipers will bolt straight up.

The only difference between the R33 GTS-T & R32 GTR Calipers is the R32 GTR's have small fins on the outer edge. Nothing that will affect performance.

Price difference between the R32 GTR & R33 GTS-T Calipers is quite large.

The R32 GT-R Sumitomo calipers are physically bigger than the R32 GTS-T ones, and allow the use of GT-R type rotors which are vented with the fins at an angle for better cooling on circuit, etc. Size diff between 32 GTST and 32GTR is 280mm vs 296mm ... much more surface area for heat dissapation. Also, better cooling than the straight fins of the R33 GTS-T rotors, even tho the size of the disc is similar. My 2c :)

Joel, have you done this brake swap yet? I am doing the same, did you use the standard master cylinder etc and just swap the brakes over?

Can confirm that these bolt on no worries

Just put them on my car on the weekend, everything fits like its meant to be

I went for genuine R33 rotors, had them slotted and machined, and went for Racebrake's Comp 9 pads on the front and Comp 2's on the rear

Bedded them in last night, and they stop heaps better than the stock 32 brakes

Big reccomendation to other 32 owners who have done a few mods

no probs

I went through it all with a mate of mine who runs a jap wreckers, it came down to R32 GTR or R33 GTSt as the only bolt on options

Racebrakes does a bracket to suit standard R32 calipers, which lets you fit a R33/34 GTR Brembo size disk - 324mm!! I would have gone these, but my rims are 16x7.5 and the brakes wouldn't clear the rim. Price wise its pretty competitive, and a good option for those who want to run 17's all the time

Roy runs this setup on his road/track car with great success

R32 GTST

Master Cylinder diam (mm) - 25.4

R33 GTST

Master Cylinder diam (mm) - 23.8

R32 GTR (Non V-Spec,)

Master Cylinder diam (mm) - 25.4

R32 GTR V-Spec / R33 / 34 GTR with Brembos

Master Cylinder diam (mm) - 26.9

So i dont see a need to upgrade the master cylinder if you have an R32 GTST and you will be using R33 GTST caliper or R32 GTR caliper.

Did around 30 laps of Mallala on friday, brakes where the best part of the car, felt very strong. Fuel pump problems meant I couldn't test them to there full potential, but it pulled up time and time again from 170+kmph no problems

I have an R32 GTS, which has hopes and dreams of becoming a gtst.. will be doing brakes + suspension + lsd before I do the engine.. so this is getting all the info down before I undertake it.. but i'm guessing a reco'd r32 gtst master cyl wouldnt be hugely expensive

How much does it cost to have the rotors slotted and machined?

I was quoted from two different places and they are round the same I'd say you'd be looking at around about $40 each machined and extra $40each for slotted or cross-drilled.

Another question and sorry if it's been asked already, I was looking at getting a set of DBA 4000+ rotors for an R33 although I'll be looking at around $900 a set.

Whats the price comparison on a set of R33 GTR (2nd hand) rotors and are they much different from the GTS-T rotors in performance?

I have a set of Bendix Ultimates (pads) going in, should they hold up for track days? or can someone recommend something better for around the same cost?

Cost of Bendix Ultimates - $120 front $109 rear (pair)

      I wasn’t able to replicate the sound anymore. It was a one time sound so maybe it was just coincidence but it was like small pebbles being dropped in a coke can.   should I try cleaning the MAF? It could be it’s functioning but dirty? I don’t know.

      Update 4: Hi all. The car drives again! Haven't driven for long, only to store it in the garage again, but the test drive was successful. The coolant and oil leaks seem to be fixed for now. Temps on the engine were also very good, while moving I never even saw 80C water during the approx. 30 minute drive. Ate up all the coolant in the reservoir though so will have to fill that even more when I go to the car next time. One thing that pisses me off is that the RPM gauge is still f**ked, I even resoldered the board twice and used copper paste on the silly screws that are used as connections. Next time I take it out I'll take apart the board and fit new components, I'll see if I can get a replacement IC for it.  I have an appointment set for 22nd of September for the engine tune to 370hp. Alignment also still needs to be done. My hope is that I can get all the legal stuff over with by the end of this season. Anyone of you have advice regarding intercoolers? Currently there is an APEXI core fitted, one of those weird hybrid ones, 600x270x76. I don't think it's bad but it's not new and now I still have the chance to change it now to legally include it in the paperwork. Only issue is that the only options that would arrive in time are a HKS Type R intercooler or generic Ebay spec intercoolers comparable to a JustJap one. Ideally I'd order a Plazmaman but it takes over a month to receive which would mean making the car legal has to wait until next season. Would love to hear some input on this. Same story for my injectors, the previous owner was a nunce and put ID 1050x on the engine. They work but are obviously not ideal at "normal" power levels. But I don't see a reason to change them unless the tuner says it's necessary. I read online before buying a different exhaust that the top secret style rear diffusers won't fit due to the size of the rear resonators. My buddy and I made it work by slightly "adjusting the shape" of the mounting bracket and making some spacers out of 3d print for the mounting bolts. Fits like a charm. Just putting this here in case someone has this problem. Even the hefty HKS Silent Hi Power rear can fits without hitting anything.

      ECU sees many times the speed than speedo does (R34 swap)

      By GTSBoy · Posted

      It's needed for rolling idle up, and I think it is a decider on VCT also.

      I mean, not really. Link ECU's can absolutely still have errors from the ECU thinking it's getting a sensor it's not expecting. I would imagine the speed at the ECU level in Nistune does absolutely nothing anyway? I assume the ECU does not do any fancy TC stuff with regards to front+rear wheel speed or anything of that like anyway. Someone who uses Nistune may be more fluent in it.
