Hey everyone, I have a 32 gtst m spec with the 4 pot brakes and 2 pot rear!! I am looking to do a brake upgrade.. So I did some research and have found I can put a adapter in and run a bigger rotor, but I am alittle confused if I can do it with these calipers!! And I also want to no if the adapter brings the caliper out towards the inside of the rim, because I have a bee's dick Clearence as it is!! I am also worried about caliper to rim Clearance!!

Thanks is advanced!!

There are adapters to suit the R32 calipers to convert from a 280mm disc (R32 size) out to a variety of common sizes, including the 324mm Brembo Skyline disc size. If they are made right, then the caliper stays centred on the disc and does not change position. Only moves outward radially.

Personally, I would rather get some R33 calipers as a basis, as the R32 calipers are flexy and groany (by comparison). The R33 are stiffer. Then you need different adapters, because R33 calipers have longer legs.

Do a search. This has been covered 40 gazillion times.

sorry for thread jacking, but i have a 32 gts 4 and fancy going for a brake upgrade.

I'm wanting to keep the car for road use, but want to get the weight down everywhere i can.

So,

Floating discs for an r33 gtr:

http://www.ebay.co.u...=item2a15729775

What parts do i need from a 33gtr?

Those(or similar)

Calipers

Carriers (Brackets)

Pads

Brake lines?(or are they the same)

And would these be any heavier, bare in mind the discs should be lighter?

Also will they fit under 17's

Any help would be greatly appreciated

For reference:

To suit that rotor you neither either:

A: The R33 GTR caliper (that is all), or the R32 GTR Brembo caliper - same same.

B: Use the GKTech adapters with the R32 gtst sumitomo calipers.

You cannot use the R33 GTST caliper unless you use different adapters (Unique auto sports).

I would not buy those eBay rotors as there is no indication who manufactured the disc or the hat. Therefore they could be yum cha made from recycled cardboard. The DBA 4000 ones would be first choice. I wouldn't even get slotted rotors if I could avoid it.

Can't tell you if you'd need different lines, but it is possible.

Im not sure what the cost of a pair of brembo calipers are, but it seems false economy to buy the adapters. Surely you could sell the sumitomo's and recoup some of the expense of the brembo's. For less than $116 for the adapters. According to the link, the brembo's have a bigger piston area, and i'd imagine they are easier on the eye.

Thanks for you're help

GTSBoy yeah i noticed afterwards looking back on them. For some reason i thought they were AP's :domokun:

A set of 2nd hand set Brembo's, front and rear go from around $1800.

You could sell a set of Skyline Sumitomo's (turbo model) anywhere from $150 - $250.

Yes, Brembo's have larger piston area.

Those rotor adapters are just so you can run a 324mm (Brembo) size rotor but still keep your stock calipers.

Running bigger rotors will allow a higher heat range so your brakes do not over heat as quickly.

Oh wow i didnt think the brembo's and the sumi's would vary in price that much.

I'm still on pom prices.

Undecided now.

Thanks for your help.

Yeah, just have a look at the For Sale section.

The price differences are quite a bit.

If you fancy a brake upgrade, start with:

New brake pads / Slotted rotors / HEL Metal Braided Brake Lines / Brake Master Cylinder Stopper.

If you still want Brembo Calipers, I believe the R32 GTR V-Spec / V-Spec II and R33 GTR calipers are all interchangeable.

Re-build the calipers and do what I listed above, but obviously buy the Pads and Rotors for Brembo size calipers.

Yes prices are in AUS Dollars :)

The question is on what grounds have you decided you want/need a brake upgrade?

If its performance then what is the current problem you are experiencing. If its part fashion/aesthetics (not having a shit, its part of the reason why I like big brakes) then its hard to go past the bracket and rotor upgrade with some nice performance street pads.

      Update 3: Hi all It's been a while. Quite a lot of things happened in the meantime, among other things the car is (almost) back together and ready to be started again. Things that I fixed or changed: Full turbo removal, fitting back the OEM turbo oil hardlines. Had to do quite a bit of research and parts shopping to get every last piece that I need and make it work with the GT2860 turbos, but it does work and is not hard to do. Proves that the previous owner(s) just did not want to. While I was there I set the preload for the wastegates to 0,9bar to hopefully make it easier for the tuner to hit the 370hp I need for the legal inspections that will follow later on. Boost can always go up if necessary. Fitted a AN10 line from the catch can to the intake hose to make the catchcan and hopefully the cam covers a slight vacuum to have less restrictive oil returns from the head and not have mud build up as harshly in the lines and catch can. Removed the entire front interior just shy of the dashboard itself to clean up some of the absolutely horrendous wiring, (hopefully) fix the bumpy tacho and put in LED bulbs while I was there. Also put in bulbs where there was none before, like the airbag one. I also used that chance to remove the LED rpm gauge on the steering column, which was also wired in absolute horror show fashion. Moved the 4in1 Prosport gauge from sitting in front of the OEM oil pressure gauge to the center console vents, I used a 3D printed vent piece to hold that gauge there. The HKB steering wheel boss was likely on incorrectly as I sometimes noticed the indicator reset being uneven for left vs. right. In the meantime also installed an airbag delete resistor, as one should. Installed Cube Speed premium short shifter. Feels pretty nice, hope it'll work great too when I actually get to drive. Also put on a fancy Dragon Ball shift knob, cause why not. My buddy was kind enough to weld the rust hole in the back, it was basically rusted through in the lowermost corner of the passenger side trunk area where the wheel arch, trunk panel and rear quarter all meet. Obviously there is still a lot of crustiness in various areas but as long as it's not rusted out I'll just treat and isolate the corrosion and pretend it's not there. Also had to put down a new ground wire for the rear subframe as the original one was BARELY there. Probably a bit controversial depending on who you ask about this... but I ended up just covering the crack in the side of the engine block, the one above the oil feed, with JB Weld. I used a generous amount and roughed up the whole area with a Dremel before, so I hope this will hold the coolant where it should be for the foreseeable future. Did a cam cover gasket job as the half moons were a bit leaky, and there too one could see the people who worked on this car before me were absolute tools. The same half moons were probably used like 3 times without even cleaning the old RTV off. Dremeled out the inside of the flange where the turbine housing mates onto the exhaust manifolds so the diameter matches, as the OEM exhaust manifolds are even narrower than the turbine housings as we all know. Even if this doesn't do much, I had them out anyways, so can't harm. Ideally one would port-match both the turbo and the manifold to the gasket size but I really didn't feel up to disassembling the turbine housings. Wrapped turbo outlet dumps in heat wrap band. Will do the frontpipe again as well as now the oil leak which promted me to tear apart half the engine in the first place is hopefully fixed. Fitted an ATI super damper to get rid of the worn old harmonic balancer. Surely one of the easiest and most worth to do mods. But torquing that ARP bolt to spec was a bitch without being able to lock the flywheel. Did some minor adjustments in the ECU tables to change some things I didn't like, like the launch control that was ALWAYS active. Treated rusty spots and surface corrosion on places I could get to and on many spots under the car, not pretty or ideal but good enough for now. Removed the N1 rear spats and the carbon surrounding for the tailpipe to put them back on with new adhesive as the old one was lifting in many spots, not pretty. Took out the passenger rear lamp housing... what do you know. Amateur work screwed me again here as they were glued in hard and removing it took a lot of force, so I broke one of the housing bolts off. And when removing the adhesive from the chassis the paint came right off too. Thankfully all the damaged area won't be visible later, but whoever did the very limited bodywork on this car needs to have their limbs chopped off piece by piece.   Quite a list if I do say so myself, but a lot of time was spent just discovering new shit that is wrong with the car and finding a solution or parts to fix it. My last problem that I now have the headache of dealing with is that the exhaust studs on the turbo outlets are M10x1.25 threaded, but the previous owner already put on regular M10 nuts so the threads are... weird. I only found this out the hard way. So now I will just try if I can in any way fit the front pipe regardless, if not I'll have to redo the studs with the turbos installed. Lesson learned for the future: Redo ALL studs you put your hands on, especially if they are old and the previous owners were inept maniacs. Thanks for reading if you did, will update when the engine runs again. Hope nothing breaks or leaks and I can do a test drive.

      No those pads are DBA too  but they have colors too. I look at the and imo the green "street" are the best.

      Yea - I mean I've seen my fuel pump which is decades old and uh, while I'm not saying this with real knowledge... but I sure get the ick at using anything in the fuel system that produced the state of that pump. Many years ago I went through multiple pumps (and strainers) before I dropped the tank to clean it out with extreme violence. I'm talking the car would do maybe 50km before coming to a halt, which resulted in me cleaning out the filter with some brake cleaner and going on my way. None of my stuff ever looked like what came out of your fuel tank. I don't think I'd be happy with it unless every single component was replaced (or at least checked/cleaned/confirmed to be clean here).

      I'm not going to recommend an EBC pad. I don't like them. Just about anything else would suit me better. I've been using Intima pads for a while now.
