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

    • You know, that is exactly the thing that I was thinking a coupe of hours ago. I even had a plan for a meme, involving one big one, another big one, and the Old El Paso girl saying "¿por que no los dos?"
    • NoS, 2 of the big ones.
    • Oh, that's grim. Something bad has been happening there.
    • Put an endoscope down the hole and saw this. Not quite all around the bore but a good 60% at least. Chin to the chest and towards further disappointments I guess.
    • 2 does "sort of" applies, maybe......but looking at what parts would be needed for the swap to get engineered, registered, and insured, and basically that's everything under the car, the modifications the make it legal would be problematic and horrendously expensive, all for a street car that just cruises around and hits a few twisty roads on the weekends Also, from looking at the NSW rules and Regs, with all modifications that is required just to make the car safe and not twist itself to pieces, and then actually get registered for street use, may still be impossible nowadays As for 1, when you add in a fresh engine, fresh transmission, rear cradle and diff, tailshaft, suspension, brakes, cooling, and all the other fabrication required, your probably looking at up to $100k to do it right, all for a 20 year old MX5 that is over engineered and you would never be able to actually use the power it has on the street, much like your beastie, which I love, but you actually track that thing and can use all of its powers in anger, in a safe environment  Hell, the old Bogan Cruise Ship had more power than I could use on the street, and in hindsight, I went a bit silly on that thing, it didn't really need the 500hp it had for what I actually used the car for, it was fun, but basically unusable on the street if you value your licence  As for cams, yeah, I'll probably book it in for them to get installed and tuned soonish, like next month after MX5 Mania are back at work....... and yes, I've already sent a email to bin the turbo quote and quote instead to install cams and a new Fluidampr balancer that will suit the 2.5 better than the OEM 2.0 balancer that is swapped over for the 2.5 install, as the balancer needs to get pulled to time the cams it's a while your in there sort of thing I did think a bit about flex fuel for a laugh, but being na, and no where really around locally anymore to get E85, I've binned that idea, so no sweet sweet corn smells are set for the car I wish E85 was more of a standard fuel, it's better for the environment, better for tuning, plus that sweet sweet smell we all love As for fitting in the family, that's not needed, as everyone in the family already owns a car that can seat 5 humans comfortably enough, the MX5 is "my toy" As for buying a car that is already built, nah, I would rather pick and choose my parts, I enjoy the process, and in the big picture, the additional cost is well worth the enjoyment, and the occasional frustration, I get out of doing it, albeit with other people spinning the spanners, and me, just paying the invoice 🤣
