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 know you don't want to hear this comment, but I can't not say it.  I just can't see 200kw being worth the time and effort. Its like guys with NA cars, putting in headers/exhaust/tune for a massive 20% jump in power. Great, the slow car is still slow and you're down $10,000.  My vote is leave it NA or price in a gearbox upgrade and shoot for at least 300KW, preferably 350KW+.  Now you have a NC that will try to kill you from time to time and will be exciting to drive

      How "plug and play" is the Haltech Pro for R33 GTST

      By Murray_Calavera · Posted

      Ah yep. The main message I want to pass on is, try not to get scared of ghosts when thinking about knock/knock detection.  What I mean is, healthy engines make noise. Knock is also noise. Your knock sensor and ECU combo are trying to determine bad noise from good noise based on how loud the noise is. The factory knock sensors and ECU are not good at doing this.  Modern ECU's are pretty decent at it, however I'd still say that you would want to verify that if your ECU says it's knock, that you actually listen to it and confirm that it is correct.  Are you familiar with the plex knock monitor?  https://www.plex-tuning.com/products/plex-knock-monitor-v3/ I expect you're the type of person that would be very keen to play with something like this. It is great knock detection and you can pop some headphones on and listen to what's going on.  Knock that you've deliberately induced in low load low RPM areas is not really putting anything at risk and is a great tuning/learning/verification tool.  I just thought this was worth mentioning based on the way you were talking about setting up a base map and the Haltech base map settings. There are better ways to spend your time then chasing ghosts and worrying about detonation in scenarios that it is crazy unlikely to encounter it.  I was also wondering, what ECU are you planning to get? Will it be long til you pick it up?

      This came quicker than I thought. It ain't even 2025 yet.

      I somehow quoted my post instead of editing it. I regret nothing.
