Hi guys,

I have been searching the forum for advice on brake advice for my R33 GTR.

My R33 GTR is pushing 300rwkw and is mainly used as a track car. I do drive it to Wakefield and Eastern Creek and the odd cruise.

The rotors are worn out and i'm in two worlds on rectifying this.

Plan A. Keep the Brembo caliper setup and fit new front and rear RDA Gold Pasivated Rotors with either EBC Red of Yellow Stuff pads. I'll also fit the front and rear air deflectors for extra cooling. This will cost roughly $2000; or

Plan B. Go with the K Sport or G4 option of new rotors and calipers. The fronts will be the 8 spot calipers with 356mm and rear is the 4 pot with 330mm rotor. I'll fit the same deflectors as part A, but this will cost roughly $4000.

As I havent had my GTR long i'm not too sure on how hard the standard 4 pot Brembos with ok rotors go.

The car is only being used for super sprints at the moment. What do other guys with GTR's run?

What's a pair of Brembo GTR front and rear calipers worth second hand?

Thanks heaps for any help you can give....

Craig

R33/34 Brembo are very good. You need to run a better pad/disc combo.

I would also advice on getting braided brake lines and a brake master stopper.

for disc i would be looking at something from the Project Mu range

Pads i personally recommend Endless cc-rg (i run them in my track gtr with ap racing caliper) they are a great pad i rate them very high! however they are dusty, noises @ low speed and due to being ceramic carbon material they can eat disc

There are plenty of options out their for pads and disc, but i generally found that the better stuff does cost alot more

Go option A. You can do better than the RDA rotors just as you can do better for brake pads than yellow stuff. Try project mu for rotors (they cool alot better than the RDA type) and Ferodo DS2500 for pads. It is important the pads work cold as well as hot and you need to be aware alot of pads do not work well cold and alot do not work well hot.

Dont worry about the rears just fit them up with a reasonable pad (DS2500).

Brake master cylinder stoppers and braided lines help alot too as does removing the stone guards from behind the rotor. Get some Motul RBF660 fluid.

Also rim selection has a BIG influence on brake cooling. R33 rims are good but I have NFI what you are running.

The last & best option you can buy is a cheap data logger to make sure you are hard on the brakes. It is easy to be too gentle.

Thanks for the replies guys, I'm running Rota 18x9 rims, they have 5 spokes and a lot of room for air.

I forgot to mention that I was planning on removing the stone guards for the extra cooling, the brake air deflectors look like they'd pump a fair bit of air on the rotors with the stone gaurds removed.

I would put ksport on the front and leave the standard rears (they are already pretty good).

I run the ksport style brakes on my race car when I am allowed to, and the stagea and z road cars all the time. they are excellent for the price and are as good as brand brakes 3x the price.

I like the EBC yellows... I run them in the G4 330mm front kit with air deflectors, no stone guards and stock rear brakes on my 300kw R32 GTR and it works well. But since you've got the Brembos not the sumitomos i'd try the yellows all round with decent fluid and air deflectors. I've run Motul BRF600 with no problems, but am going to try the Nulon to see how it goes since its a third the price. Motul = 310 degress, Nulon = 280 degrees IIRC.

If you go plan B you'll still want the air deflectors.

EBC's really are very bad. I would highly recommend anyone that likes them trying a different pad. Its amazing how much better pretty much any brand name pad is than the EBC's. Endless and project MU aren't expensive for no reason.

On a budget the Hawk's are very good too even if they do lack a bit of modulation.

The only pads EBC are better than is Lucas and the AR pads that some people seem to like.

Note: This is assuming you want the best braking and are pushing really hard. If you don't care about ultimate lap times and are going for fun it doesn't matter.

anyone used the wilwood brakes? I'am looking at getting the 6 pot front 355mm and 4 pot rear 320mm.

We just did a group buy for a kit I put together for the front.

Rear is a problem because no Wilwood setup is designed for the Skyline rear handbrake. Been looking into options of a DBA rotor to work in conjunction with a Wilwood caliper but even that is proving to be a problem due to nothing appearing to be suitable.

I'm currently trialling some very cheap 2-piece rotors to fit stock brembo's - If they work out i will organise a group buy as they are almost half the price of DBA rotors. Got 2 track days over the next 2 month so I'll find out.

They are noisy as hell at the moment so not sure if the DS3000's bed in properly. Will get them out and give them a scrub over the next week or two and find out. Could be rotor composition as well though.

I've also been trying to organise a GB for front sets of the K-Sports but its proving a bit difficult at present.

DS3000's are also terrible when cold. But they are warm enough by the time i get to the end of my street (two deliberate stops from 60km-20km/h) so that doesn't worry me too much and they only get better from there.

Might try some 2500's as well but i am very hard on brakes.

2500's are surprisingly good Ash. I hammerred a set pretty hard over a range of conditions from street to 20 minute track sessions and never had any grief with them, They dont need much warmup and are pretty quiet too.

Would reccomend for a street track car.

Ye i have 2500 in the GTS-R and they are a good pad even for the street.

I'll see how i go with the 3000 first over 2 track days. I am testing the rotors for wear rate/reliability so the 3000 should give the rotors a good test when im hard on them.

If they dont stop squealing though - 2500 are going in. I dont drive it daily (maybe 1-2 times a week) so i dont mind so much at present.

the 4 spot wilwoods I've seen were pretty poor....too much caliper flex. But like all manufacturers I'm sure htey have different models, hopefully the group buy ones are more solid

    • The car/ECU will have all the sensor that it needs and expect to have. I think i do not have to explain to you how the Link is way better specialy if you have swapped engine   I just do not want to deal with any "problems" cuz i have only Nistune which i learned is not that great and in my case cant even deal with that speed problem (Link can) And of course it will be way more easier to tune and diagnose and safe. And for the ECU/speed problem...i dont know.
    • Per Mark Roberts of Sonictune: Mark Robert Author At this time, no. No ETA either 2016-17 models. You will be able to purchase and install a 2018.5+ TCU though   TCU purchasing and pricing info! As we near the release of TCU tuning, I am going to answer some questions I get asked often.   What do I need for TCU tuning? At this time, you will need a 2018.5+ TCU to be able to tune. If you have a 2016-to early 2018, you will need to replace your TCU with the newer version. One good way to know if your TCU is good is if you have auto upshift in manual mode in 1st gear around 6500 rpms. If your manual 1st gear goes to 7k rpm and will hit the rev limiter unless you shift, you have the older TCU.   Why do I need to buy another ecu license/phone flash if I already have it on my ECU tune? The TCU is its own computer module. It is completely separate from the ECU. Because of this, you will be required to purchase a TCU license and, if your tuner has it, the phone flash license required to tune it via phone/bluetooth.   Do I need TCU tuning? TCU tuning is NOT required. However, the faster your setup, the more it will assist in track and dragy time consistency.   If I’m ECU tuned by (tuner A) can I get my TCU tuned by (Tuner ? Yes, since it’s a different module and a completely separate flash, you can have two different tuners. However, it is highly recommend that you have both tuned by the same tuner. For me, my TCU tuning will directly complement my ECU tuning style and features and running my ECU and another TCU or vice versa MIGHT cause some issues. At this time and for the foreseeable future, I will only be tuning my current ECU tuned customers TCUs.     I have a SYVECS AWD controller. Do I still need it? Yes! The AWD controllers main job is to control your AWD system. However, with TCU tuning, you will no longer need the auto-shift function as that will be done through the TCU. The AWD controller will still be very beneficial for racers looking to maximize traction on the launch.     Shift schedule changes: holding gears longer at lower pedal input as well as max shift rpm changes. Please note, the new ECU race rom coming out will address 90% of the shitty drivability issues these cars have through custom maps from myself and Racebox—as well as others I am sure.   Increase shift speeds: as seen in the videos I’ve been posting, the TCU shifts much faster once tuned.   Increased shift pressures: as also seen in the videos, much firmer full throttle shifts.

    • The fancy pants red shock tower brace is finally incoming from MX5 Mania, getting it shipped from 'Merica has been a long and problematic process, and GWR, the 'Merican supplier will not ship directly to consumers outside of the US, Mania basically had to order a heap of them, the colour choice was silver, or red, and we all know anything red adds 5 killerwasps of dynotorques..... Whilst it does fit over a 2.5, and I've seen a few photos and videos of it being installed and fitting, google also says it might get real close to the FAB9 intake front runner, people in the US says it does fit with the FAB9 intake, except for one person who said it slightly touched.......so there is that.....LOL..... As it seems that I am the first in AU to have this combination of parts there's no local knowledge about fitment, so I'm just a willing guinea pig in this endeavour, I'll cross my fingers and toes and hope for the best In other news, I ordered stuff from China  on the same day I ordered the 23° silicone bend from Victoria, the stuff from China arrived a day ago, the 23° silicone bend is still travelling around Australia thanks to Australia Post, and "may" be here next week
    • Very good news...I contacted Racebox about it last night. My car is a 2016 so remains to be seen if it is compatible, requires a TCU swap, or is impossible.
