R33 Gtr Brake Upgrade

[XGTRX]

Hey guys just wondering if you can help me out. I have an r 33 gtr full weight and getting an engine done which should be pushing 350+kws. Want to do so track days and throw the car around a bit at some events. I have standard brakes that are due for rotors and pads shortly. I have been researching for months and totally confused. I see that many have trialed a massive amount of different setups. So my question is what is the best front brakes I can fit in my 17 inch LMGT1s with a street track tyre like Achilles 123.

Options would be a larger rotor with compact calipers or larger caliper with a smaller rotor. Are there much differences in performance with lets say a nascar 4 pot brembo and a 6 pot other brand caliper. What about the F50s are they still a great improvement over the standards with great rotor pad combo. I know that there is a great group buy on the d2s but they are quite bulky and am very restricted on their rotor size.

So in short is there a compact caliper that can be used under my 17s that will out perform or equal the current crop of 6 and 8 pot entry level options or other 6 pot calipers. I would rather go the largest rotor I can because of the the inherent cooling advantages with the best compact caliper i can afford.

Thanks and i would appreciate your assistance.

I've been using Alcon big brake kit 343 mm rotors http://www.jdl-brakes.com/alcon-adv-extreme-brake-kit-front-6-pot-o343x32-nissan-skyline-r32-r33-r34-gtr.html with low offset 17" Enkei wheels, for two years. They perform very well on track, with yellow Pagid pads, much better than AP kit that I had on R32. No BIAS issue with stock rear calipers and DBA rotors. I'm going to sell my front kit very soon, and change for Alcon 365 mm kit with 350 mm rears http://www.jdl-brakes.com/special-offer-alcon-adv-extreme-brake-kit-front-and-rear-nissan-skyline-r32-r33-r34-gtr.html but need to find correct wheels first.

So now I have reached a point where I need to make a decision.

I have LMGT1s 17s and I need to get new rotors and pads.

Car makes about 350 and want to throw it around a track and is regularly driven.

Looked at the UAS upgrade kit with some braided lines and consists of this:

UAS 343MM BIG BRAKE KIT FOR NISSAN SKYLINE GTR

KIT INCLUDES:

343MM SLOTTED TWO PIECE ALLOY ROTORS

HATS

BILLET ALLOY CALIPER ADAPTERS TO SUIT FACTORY CALIPERS

CAP BOLTS

CUSTOM FERODO 2500 PADS

SUITABLE FOR R32 / R33 & R34 GTR

Then I see this on eBay

Quote:

Up for sale is a set of Brembo F40 calipers that was bolted to a Nissan R34 Skyline.

These brakes were purchased secondhand, and since the purchase, they have had a seal kit put in them and have been powder coated gloss black. Since the work has been done, these brakes have not been used whilst the vehicle has been driven as they are off an unfinished project car. The whole kit comes with 343x32mm RDD Rotors, RDD alloy radial mounts, endless blue pads and braided lines.

Price difference is no big deal but I am just thinking long-term.

So will I get a noticeable advantage with selecting the f40s in performance or durability or is the standard caliper UAS upgrade enough for my application.

Love my 17s so bigger size is not an option. I just want to do this once and not regret my choice.

Thanks

Well for what it is worth I am running the F40's on a GTR with the DS2500 pads. They work pretty well, but I did also get the Brembo rears and a V spec master cylinder to go with the callipers.

343 is an option. Project Mu are another brand of rotor than can be bought in that size. Basically you can run any rotor you like as long as the adalptor lines with the "offset" on the hat/rotor. They may not all be the same on the aftermarket rotors, so be aware. Also the bolt size will be wrong on the adaptors as they are off a 34 so you will need to get some more made up - not too hard to do.

The good thing about hte F40 is:
The pad area is larger than the GTR Brembo calliper.

The piston area is the same.

The DS2500 pad is not custom. It is the same part number as used on the AU Falcons.

So bias is not changed on a 324 rotor from standard and only slightly on a 343.

[XGTRX]

So the adaptors mounting holes need to be opened up for the 33.

Did you get any real advantages with the F40s as in less pad and rotor changes, less fading/heat issues on the track?

The other way around. The R34 uses 14mm (I think) bolts to the 32's 12mm's. So the holes in the adaptors will be for 14mm hence too big. You can either modify the hub, sleeve the adaptor or make new ones.

Well a bigger pad gets a little less temperature and cools a little better. There is not alot in it but everything helps.

[XGTRX]

Has anyone used both on the track. Should I expect a lot better overall performance from the F40s. Is there another preferable setup for 17s?

[djr81]

I went from the Sumitomo package to the F40. Not a massive difference in the performance but feel and longevity were heaps better. The cooler you can keep pads/rotors the cheaper they are to run. The bigger they are the cooler they run.

There are a bunch of cheapo China options if you want to go in that direction.

I got the chinese option - 330x32mm 8 pot G4s after reading some of track ppl here saying they're a good thing. Very happy with them. IIRC Nismoids group buy is still on....

What's your experience with them. What brakes did you come from?

[Mr. Untouchable]

I bought my G4's off a mate who ran them for roughly 3 years racing in our super series here in tas, in that time the car was running from 260kw odd up to 450kw plus, held up amazingly well only one rotor replacement in that time and at the very end as they have done one days work or less then I bought them. I wouldn't run g4 coilovers or probably anything else they sell but their brakes ARE proven. There are heap of pads that will fit them too as they take a AP size pad.

Guys, you should to seriously consider JDL offer for Alcons. Top quality kit, for less than you can get locally. Links below ( second link )

I've been using Alcon big brake kit 343 mm rotors http://www.jdl-brakes.com/alcon-adv-extreme-brake-kit-front-6-pot-o343x32-nissan-skyline-r32-r33-r34-gtr.html with low offset 17" Enkei wheels, for two years. They perform very well on track, with yellow Pagid pads, much better than AP kit that I had on R32. No BIAS issue with stock rear calipers and DBA rotors. I'm going to sell my front kit very soon, and change for Alcon 365 mm kit with 350 mm rears http://www.jdl-brakes.com/special-offer-alcon-adv-extreme-brake-kit-front-and-rear-nissan-skyline-r32-r33-r34-gtr.html but need to find correct wheels first.

$3300 mmmm I am sure value for money they are awesome but may be an overkill for my application

[ichi-go]

Nothing is value for money if you are comparing to G4s brake

Suppose if your going brand new caliper. F40s out perform them don't they and are cheap to run. Much better quality caliper too?

[MrStabby]

What's your experience with them. What brakes did you come from?

Used them at Wakefield, Eastern Creek and Marulan with both EBC yellows and QFM A1RMs, and all seemed to work well, but im no expert. I also have the UAS air deflectors that go on the radius rods.

Before i got them i had the UAS 327mm kit which used DBA4000 GTR rotors (which cracked - the crappy old design) with the sumitomos spaced out, Had braided lines and was using DS2500s and DS3000s. I found the pedal to be harder and felt more positive (so i guess the chinese calipers are more rigid that the sumis). Nice big pads too.

Agree with Mr Untouchable - wouldn't touch the coilovers but the brake kit is good.

First things first...by the sounds of what you are doing...std R33 GTR Brembos will be fine. Have a look at Ant's vids. Seriously quick track car with similar ir not more power than you in his full weight daily driven car on semis. He ran std setup for a long gtime with DBA 5000 2 pce rotors. The car had a bit of an appetite for rotors and pads, but thats because he does so many bloody track days!

I think you need to just throw some good quality pads and fluids in the car and get out there and go from there. Std kit is pretty damn good if onky doign sprints and fun days

[XGTRX]

Thanks Roy. So what pads and rotors do you recommend for my application.

I have a R33 GTS-T and am currently looking at the 2 and link of Alcon front and rears (365 front and 350 rear). The car is now 100% used for racing and sprints.

I am a real noob when it comes to this stuff.

Will these fit under my P1 racing 17x8 rims with a 22 offset? I am also looking to buy a couple set of Enkei's rims in 17x9 and am unsure of what offset I will need to fit these brakes and the car without cutting or flaring the guards.

[XGTRX]

Nah from what I have read 343mm seems to be the limit for 17s
