Hi,

I have a R33 GTS-T and I am looking to upgrade my brakes to the largest calliper and rotor combo that I can fit under 17" rims.

I am looking for 2 piece floating rotors but if you do not have rotors that is ok as I am just as happy to purchase rotors brand new.

The car is a track car.

Message me with what you have with price, a photo and location.

A reasonable budget, it depends on what is on offer.

Currently I have P1 Racing 17x8 +22, I am lokoing to move to a 17x9 (unsure of offset yet).

I am currently using standard calipers and DBA4000 on the front and standard rear rotors. I am melting the DBA4000's.

My thoughts are to go to a bigger caliper and rotors. Planning on using 2 piece Performance Friction rotors front (they are cheeking atm if they can custom up a set of rear hats.

I use the car for sprints and now racing at Barbagallo (WA), this track is very hard on brakes.

I know I need larger rotors and a better cooling setup. I have been thinking about GTR Brembo calipers front and rear for the extra 8% pad coverage with 330mm fronts and 300mm rear rotors.

Shaun,

Just so you know the F40 Brembo is another 10% pad area above the GTR Brembo and is a radial mount. Not that it is any recommendation but it is what I have albeit on a 324 rotor. You can get a 343 rotor which is about as much as you can shove under most 17" rims although some can fit in 355 which is an easier rotor to source.

Just to give you an idea.

I went up to a 324mm GTR rotor with a spacer on the caliper. I got 1 extra track day out of the pads a 2 laps more each session.

Moved to 330mm rotor with ksport 8 pot piston (APP 5555 design), 3 more track days out of the pads and the brake didn't go off during the session.

Interesting feedback :yes:

There is nothing either APP, or AP CP5555 about those calipers. They use the same pad shape...thats it. My calipers use a Porsche pad, just like many Harrops do...does not mean they are a Porsche caliper.

If you are going gung-ho then 355 with a good caliper can fit in SOME 17" wheels. 343mm is a much safer bet for rotor size and 17" wheels....but even then some 17s wont clear 343s if they are a cast design wheel.

That leaves you with the far more common 330-332mm rotor size and the plethora of setups that opens up to you. Frankly, pick budget and just go shopping...and wouldnt bother upgrading the rears. They are generally the same rotor size as std, just a little wider (2mm) and the caliper pistons are a tad bigger but you are hardly chasing more braking from the rear of a Skyline. If you have cash and done every other mod to reasonably get pace from the car then grab some rears if you can find them cheaply but hardly needed, especially if purchasing rears means you penny pinch on the fronts.

If you want my 2c and you have the cash, then grab a genuine AP 6 pot kit running 343mm rotor. Otherwise just grap one of the Taiwanese kits with a 330mm rotor for 2k odd...loads of people run them with great success

I have 6pot AP 5555s on the front of my 33 GTR with 343mm rotors and they fit under the 17x9" stock GTR rims, Enkei RP01 17x9" and my BBS (RSR?) 17x9"s. At the time these were the biggest brakes I could find which would fit under the 17s I had. Since I've put these on, albeit ditching the Ferodo pads which come with them, I haven't had brake fade even after 60km Targa stages or 30 minute sessions on the track.

They are quite $$$ but like most things you get what you pay for. Rotors are a proper floating design with curved vanes so actually dissipate heat unlike a lot of other brands "motorsports" rotors.

Semantics, similar design then. Whatever. The Thai spec ones are 1/3-1/2 the price.

I wouldn't bother with the 356mm, 330mm is fine. Gives you easy option for 17" as well. I've run 8 pad sets through the caliper on two sets of rotors.

$200 pad sets and $750 rotor sets.

So after a lot of tooing and froing I have made a decision.

All feedback has been welcomed and appreciated. I appreciate the time you have taken to write down your thoughts.

I looked at some of the Taiwan stuff but the wear of rotors and cost of replacement rotors did not make sense to me. You have to remember I am in WA so always getting hit for shipping $$$$.

I have purchased a brand new set of 4 pot 335mm Alcon kit for the fronts at a huge discount to retail.

My build has always been to a budget but sometimes I am happy to spend the coin on certain areas that I believe will yield a return in performance, safety or long term cost effectiveness.

I will update my build thread when received and installed.

After this I need to sort out the rears which I think will be custom hats, dog bone to 299mm performance friction callipers. Not as expensive as you would think according to the quote I received.

    • Yea that’s why I said ima test them with multimeter and see the reads.
    • Only at idle. Isn’t a problem when rev it seems.
    • @Haggerty This seems silly to ask, but are you confident in your ability to tune the Haltech?  
    • Next on the to-do list was an oil and filter change. Nothing exciting to add here except the oil filter is in a really stupid place (facing the engine mount/subframe/steering rack). GReddy do a relocation kit which puts it towards the gearbox, I would have preferred towards the front but there's obviously a lot more stuff there. Something I'll have to look at for the next service perhaps. First time using Valvoline oil, although I can't see it being any different to most other brands Nice... The oil filter location... At least the subframe wont rust any time soon I picked up a genuine fuel filter, this is part of the fuel pump assembly inside the fuel tank. Access can be found underneath the rear seat, you'll see this triangular cover Remove the 3x plastic 10mm nuts and lift the cover up, pushing the rubber grommet through The yellow fuel line clips push out in opposite directions, remove these completely. The two moulded fuel lines can now pull upwards to disconnect, along with the wire electrical plug. There's 8x 8mm bolts that secure the black retaining ring. The fuel pump assembly is now ready to lift out. Be mindful of the fuel hose on the side, the hose clamp on mine was catching the hose preventing it from lifting up The fuel pump/filter has an upper and lower section held on by 4 pressure clips. These did take a little bit of force, it sounded like the plastic tabs were going to break but they didn't (don't worry!) The lower section helps mount the fuel pump, there's a circular rubber gasket/grommet/seal thing on the bottom where the sock is. Undo the hose clip on the short fuel hose on the side to disconnect it from the 3 way distribution pipe to be able to lift the upper half away. Don't forget to unplug the fuel pump too! There's a few rubber O rings that will need transferring to the new filter housing, I show these in the video at the bottom of this write up. Reassembly is the reverse Here's a photo of the new filter installed, you'll be able to see where the tabs are more clearing against the yellow OEM plastic Once the assembly is re-installed, I turned the engine over a few times to help build up fuel pressure. I did panic when the car stopped turning over but I could hear the fuel pump making a noise. It eventually started and has been fine since. Found my 'lucky' coin underneath the rear seat too The Youtube video can be seen here: https://www.youtube.com/watch?v=uLJ65pmQt44&t=6s
    • It was picked up on the MOT/Inspection that the offside front wheel bearing had excessive play along with the ball joint. It made sense to do both sides so I sourced a pair of spare IS200 hubs to do the swap. Unfortunately I don't have any photos of the strip down but here's a quick run down. On the back of the hub is a large circular dust cover, using a flat head screw driver and a mallet I prised it off. Underneath will reveal a 32mm hub nut (impact gun recommended). With the hub nut removed the ABS ring can be removed (I ended up using a magnetic pick up tool to help). Next up is to remove the stub axle, this was a little trickier due to limited tools. I tried a 3 leg puller but the gap between the hub and stub axle wasn't enough for the legs to get in and under. Next option was a lump hammer and someone pulling the stub axle at the same time. After a few heavy hits it released. The lower bearing race had seized itself onto the stub axle, which was fine because I was replacing them anyway. With the upper bearing race removed and the grease cleaned off they looked like this The left one looked pristine inside but gave us the most trouble. The right one had some surface rust but came apart in a single hit, figure that out?! I got a local garage to press the new wheel bearings in, reassemble was the opposite and didn't take long at all. Removing the hub itself was simple. Starting with removing the brake caliper, 2x 14mm bolts for the caliper slider and 2x 19mm? for the carrier > hub bolts. I used a cable tie to secure the caliper to the upper arm so it was out of the way, there's a 10mm bolt securing the ABS sensor on. With the brake disc removed from the hub next are the three castle nuts for the upper and lower ball joints and track rod end. Two of these had their own R clip and one split pin. A few hits with the hammer and they're released (I left the castle nuts on by a couple of turns), the track rod ends gave me the most grief and I may have nipped the boots (oops). Fitting is the reversal and is very quick and easy to do. The lower ball joints are held onto the hub by 2x 17mm bolts. The castle nut did increase in socket size to 22mm from memory (this may vary from supplier) The two front tyres weren't in great condition, so I had those replaced with some budget tyres for the time being. I'll be replacing the wheels and tyres in the future, this was to get me on the road without the worry of the police hassling me.
