Brake Grade Upgrade For My R33 Gts-T


Recommended Posts

Hey Guys

Going to upgrade my R33 GTS-T in the braking department from standard rotors , brake lines & brake fluid. Just finding the brakes aren't quite doing the job for a car which has 400rwhp ! It's used for street use & hard driving in mountains , with the intention of some light track use in the future , once brakes have a bit more bite in them.

These are my two options i am looking at , keeping in mind i want to keep the standard calipers for both front & rear .

Option 1 - Project Mu B Spec pads front & rear

UAS Master cylinder stopper

Goodridge braided line kit front & rear

DBA 4000 series rotors front & rear - Swap over from factory size

Motul RBF 600 brake fluid

Option 2 - Project Mu B Spec pads front & rear

UAS Master cylinder stopper

Goodridge braided line kit front & rear

Motul RBF 600 brake fluid

DBA 4000 series rotors rear

UAS Alloy adaptors upgrading to 324mm front UAS two peice curved vane rotors

Will i notice much difference between the two upgrades going from the 297mm rotors to the 324mm in the front. In words is it worth the extra $1200 !!

:thanks: Josh

You should consider the D2/G4/Ksport etc 8 piston kits instead - they are around $2k and come with larger discs (330 or 354), 8 piston calipers, new pads and new brake lines. Excellent performance for the price.

P Mu pads are just expensive or what they are. If you just want pads with more bite contact GSLRallysport on here and see which pads they suggest.

+1 to above. Although if he doesn't have true 18" wheels the larger rotors will be a problem.

I'm getting my trial set shipped (356mm/8piston) soon for the Group Buy this week or next. Just wanna make sure it's legit, fits up etc.

Will come in less than 2k.

Is this kit a bolt on application or will i have to mod things to make them fit ? Also do they have a website i can have a look at ? Cheers

My rims are 19 x 8 . Also have u guys done any upgrading to the rear brakes aswell , if not will the front end have to much braking power & upset things in the overall braking department ?

Just bought ATTKD 8 piston front brake kit with 356mm rotors off Just Jap. Black & silver calipers are a bit better looking then the bright Orange K sport ones !

Also bought 297mm DBA , T slot rotors for rear with Project Mu B spec pads. Set of braided lines & Cusco Brake cylinder stopper. Last of all Motul RBF 600 brake fluid. Can't wait for all to be fitted , should make a hell of a difference in the braking department :wub:

Sounds interesting! look forward tothe progress of this & your testing results.

Will it come with local warranty (if any?)

I've got D2 8 piston calipers up front and 4 piston calipers at the rear with 356mm rotors all round.

I can get them to fade at Sandown but not at Winton. I need to improve the cooling to the front rotors, once I've got good ducts in place, they'll probably be fine. What'll kill them is semi slicks that are coming soon.

semi slicks will not be a problem - the better your tyres, the less you need to punish the brakes ;)

Next thing i'll be looking at is better tyres , any one have any suggestions on a good road tyre for 19 x 8 rims ? I am currently wearing Achilles ATR Sport tyres which i find good & handle the mountain roads fairly well. But once the brake upgrade is fiited could be quite a different story !

Depends on your exact needs.

I have settled on S compounds as an all rounder and am happy with S compounds... still doesn't provide the traction and braking i want but pointless going to R compound for me as i won't be able to get the heat into them on the street.

To be honest, almost any S compound will be a major upgrade over Achilles (unless you have the achilles S compounds? I seem to remember they had a set).

Otherwise any UHP street tire would be good too e.g. Pirelli P Zero Nero or some crap like that, or Michelin Pilot Sport PS2 but they're not cheap but you'll find your 19" size.

Something a bit cheaper could be Kumho Ku31 or Goodyear Eagle F1 asymetric.. the upgrade won't be dramatic though.

I'm finding dba4000 slotted f/r with pads, lines, fluid, master cyl brace and S compounds to still not be enough for only 320rwhp :( but i might be too picky.

Thanks for the info on the tyres . I'll look into the tyres which are S compound & that should point me in the right direction. I just want a tyre which has plenty of grip & makes the car feel nice / stable under hard breaking. Don't really care if they wear a bit quicker due to being a softer tyre , cause my skyline is only a weekender & doesn't rack up a huge amount of K's !!! :thanks:

Will test drive them tonight but I dare say my shitty front tyres will not like them. Definetely gotta get some KU36's on the bitch asap.

just get a set of Kumho KU36... cheap and heaps of dry grip... I run Harrops with 355mm rotors and 275 wide KU36 and I have to staaaand on the peddle to get the ABS to kick in

I heard the Kumho's KU36 weren't real good in wet weather & more of a track tyre. I was thinking of getting the Kumho KU31 or the Falken FK452 tyres as i mostly use it on the street .

Nice upgrade mate , did u buy it as a whole brake upgrade kit ? Are they 6 or 8 spot calipers & what size rotors ? Also was it much effort to do urself , as i'm thinking of taking mine to a local mechanic for a bit of help. Haven't had much to do with brakes before so thinking of letting someone with a bit more knowledge do the major work & i'll give him a hand !!

    • As an extension of that thought, if you do not also have adjustable front radius/traction arms, and if you have not had them properly** set up at the same time as any adjustments to the uppers (when camber is being set) then you  will likely have an excessive amount of bump steer and the rear end will actually be worse off. **I built a bump steer measuring setup with a laser, mirror, etc and spent.....a whole day, and most of another day, getting both sides of my car to minimum bump steer. (Was a slow effort because I was designing/building the rig as I went, to start with). Then I had the rear camber adjusted a little at the next proper wheel alignment and had to set the bump steer rig up again to dial out the increased bump steer that it caused. Car's rear end behaviour was substantially nicer afterwards. To get that done by a specialist would be.....near impossible in most places. Almost no chassis/wheel align shops would be willing to put up with the f**king around. And the fee would be horrendous. Racers and shops that cater pretty much only to racers would probably be set up to do it and do it reasonably efficiently, but it would still cost many hundreds of $$. My time should be worth even more than that, but fuddling about with the car is also therapy, so meh.
    • So about 10 years ago, i bought a brand new Greddy FFP (a legit one), which i have always wanted to put on. Now i know there is no real performance gain, however i have always been a fan of how much it simplifies the engine bay and makes servicing that much easier. The reason i never got round to installing it is that it just seemed more trouble than its worth for basically a stock car.. All mods to date are more suspension/handling/drivetrain, so today i made the decision to start with the more serious (and expensive) part of the mods, the engine hardware.. Today i purchased: Xspurt 1000cc injectors (1/2 height) EFI Hardware fuel rail GFB FX-R fuel pressure regulator necessary fittings to direct mount regulator to rail NZ Wiring trigger kit 82mm Bosch DBW throttle body Taarks 82mm DBW to 3" hose clamp adaptor Outsider Garage 350z pedal kit Franklin Performance R35 GTR coil kit There is still a bit of time before this will make its way into the car, as i want to have a complete cold side assembly, with a sub-harness all good to go. As a note, i have heard the the 82mm Bosch DBW throttle unit is basically a direct bolt on with some very slight mods to the plenum, so will be testing this out.
    • Awesome, thanks for your help👍👍
    • https://nissan.epc-data.com/skyline/ecr33/3909-rb25det/engine/211/ https://nissan.epc-data.com/skyline/ecr33/3909-rb25det/electric/278/ The hose on the left closest to the firewall is a heater core pipe. It also goes to the oil/coolant heat exchanger and the throttle body. The hose it attaches to is 92400, which is the upper heater core hose. The one to the right of that goes to the lower heater core hose. In the absence of proper photos at each step showing how everything is laid out from the factory the EPC is as good as it gets.
    • Hi All I’m Rene, based in Hamilton NZ and am the owner of a silver 1996 R33 coupe. I bought the car in August 2009 and I am the first owner in NZ. When I first purchased the car, it was a bone stock gts25t automatic with approximately 75,000kms on the clock. From memory I paid about $8,600 from the dealer:   Mod History So over the years I have done a few modifications. The first real mod I did was wheels (on stock shocks) and tints: Now this was done prior to finding out about SAU/SDU, meaning I had no understanding about things like fitment, so was rolling round in 4x4 spec for some time.. Eventually I became a bit more educated (thanks to the forums) and started to do things a bit better. Rather than write a novel of the last 13 years of ownership, I thought I’d just add the list of mods: Exedy lightweight flywheel Exedy full face organic clutch Braided clutch line Adjustable whiteline swaybars (front and rear) Znoelli dimple drilled and slotted brakes with performance pads (front and rear) Braided brake lines (front and rear) BC Gold adjustable suspension Hicas lock bar Tomei upgraded fuel pump Genuine Greddy front mount intercooler kit 3” exhaust from turbo back, with 3” bellmouth dump R34 OP6 turbo Mishimoto aluminium radiator ATP catch can and speedflow fittings 17x10r and 17x9f wheels with Falken fk452 all round Innovate mtx range gauges (oil, wideband and boost)  Funnily enough, this list was actually composed to add to the classified to sell it, however I just can’t bring myself to do it. Did you say M3 @Dose Pipe Sutututu? Anyway, this brings us to the current day The car now has 105,000ks and is barely used as I just don’t have time and it doesn’t really suit being my daily (as I need something more suitable to visit construction sites). I don’t think I have even driven it in the past 12 months.. Build Direction The plan here is to go for a bit of an OEM+ type vibe, so nothing too extreme. I am also planning to modernise a lot of the vehicle with things like new ECU (decided on Haltech), DBW, cruise control etc. The power will eventually get increased with an end goal of around 280-330kw. I am keen to get a bit more motivation and actually get this car build back up and going again. It may not be the fastest build, but I’ll get there eventually! And then I’m less likely to try sell it..
