Stagea brake upgrade options?

[jake32]

I thought the 260 brakes where the same as R34 GTR

i thought it was R33 GTR v-spec

[Sydneykid]

i have 3 gtr`s atm ... stagea will outbrake them all including one with braided lines and fancy coloured pads

not sure if its just brembos but   disc/pads(genuine)and calipers are superior combination to any gtr i have driven

sk or any stagea owner  thinking about upgrade can drive mine and find out for themselves...

you should be surprised

We don't run ABS on race cars, far too dangerous. So the comparison I make is that the driver can lock the tyres up with either set of callipers fitted. That means the braking distance is purely relevant to the drivers ability to modulate the pedal (and avoid lock up) and the grip of the tyres. The braking ability of the standard 4 spot Nissan callipers exceeds the tyres grip, so I don't care what callipers I put on the car, it ain't gunna stop any better.

What I find happens quite often at driving schools is that people stop faster if the pedal is lighter (ie; they don't have to push so hard). But that is not a reflection of the true maximum braking ability of the car. ABS just complicates this as the callibration of the ABS controller and its programmed logic can make even good brake callipers work below their efficiency.

So disconnect the ABS, stick the same tyres on both, modulate for 20% lock up (supposedly the best level for max stopping power) and I'll bet there is diddly squat difference in the stopping distance. Allowing for vehicle mass of course.

This is of course not the case with the standard, single piston Stagea callipers, at the moment I couldn't lock the tyres up after about 5 minutes of hard driving. They are simply goooone. Plus the warped disk shake is most disturbing.

Man I need to learn so much - dont know anything about brakes... can someone have a look at the stagea replacement brake parts available from this Jap supplier (link below) and tell me what I am looking at... calipers? rotors? pads? single piston? four piston? which set should i buy what am i getting if i buy them?? The only english i can make out is the words "6 pot" and "4 pot"

SK , which front DBA rotors will fit and can we get some 4pot calipers that provide the

same clearance etc as the std stagea ones, and fit under 16" wheels.

Just for street "work", I reckon decent pads and some brand new rotors will be fine. I'd like to get them both at the same time.

My 5 cents.

My brake upgrade has just finished and although I didn't think the original ones weren't that bad my advice to you all is upgrade now if you are thinking of making any mods to your car.

I went the GTR33 brembo way but I think any 4 spots on the front and twins on the back are the way to go, with some decent pads.

My Stag is a series 2 with ABS and 17 inch Rays N1 rims.

Discs and calipers bolted straight on, with mods to the inner rotor/disc shield/cover using an angle grinder as I didn't want to take off the hubs as the 33 rotors were bigger diameter than standard.

Try and get the original R33 hoses with the calipers as it makes life a bit easier to install as my connections were the banjo fitting where the 33 were the screw in type, but the banjo fitting will bolt up if you file(fine) flat the surface they bolt to(take off all the paint) and shorten the banjo bolt by about 1/4 inch. Sound a bit rough but I had them checked by a brake shop who said it was OK and soon to put on braided lines anyway.

My braking is now awesome especially with the ABS and if it saves me once, it will pay for itself,(well nearly) in not having to pay excess on my insurance.

The master cylinder is fine in coping with the extra and bigger brake pistons.

I had a chance to compare the size of the m/cylinder with the one on a R34GT and visually the Stag one looked bigger but I didn't have a tape measure to be exact.

Remember my Stag is a series 2 so I don't know about series ones and although I used Brembo's the fittings should be the same as 4/2 spots off a R33.

I hope this can help someone and sorry no pics.

PS 16inch rims will fit on the back but not on the front.

Digging up this old thread - can anyone confirm that R33GTR Brembos bolt straight up to the S1 Stagea? I have GTT brakes at the moment which are fine for the road but I want a little more sustained stopping power for the track but can't afford $2k plus brakes (can get some Brembos, front only, for under $1000).

[TheKenso]

Have been reading throw this pages now, as far as i understand the rs4 can have a gtst (witch i alsow fiund out was same as 300zx z32) upgrade front and rear, but wil they bolt straigth on the original bolt holes for the original calipters? or wil i need an extension to make them fit?

Bolt on

Does the same apply for series 1&2?

What models are compatible with series 2 auto AWD?

The only ones worth fitting are GTT or GTR. You may have to remove the olives or trim the rear backing plates in some cases and there are two diameters of bolts but that is easily fixed. All the info is in the thread. Use Google to search.

I've tried to search Google and am not finding many answers, I also trawled through over 70 pages of tangents and unrelated conversations  that vaguely resembles a discussion on braking applications and parts required etc on here and still learned 5/8ths of bugger all regarding the actual difference in the overall width of different calipers that are available, and also which model vehicles are directly compatible with the a series 2 stagea, all I can surmise is that anything GTR will be a close match other than bolt diameter, so short of purchasing every type of brake setup available for a trial and error based approach it's proven to be a frustrating exercise to find a caliper that'll work with the wheel that I have 

[KiwiRS4T]

I replaced the stockers on my AWD Stagea with GTT brakes (a big improvement) but then went to 330mm D2s.  I was running Rays Volk TE37 at 17 x 9 and also ran some random 17 x 8.5in at the track and both sets cleared the D2s so If you are having so much trouble I suggest you get some other wheels (or some spacers).

I did get some 18s later off a Nissan GT coupe Sport Edition (see pic) and also a pic of my track wheels (don't know what they were - just called "M" s

[oxford1327]

I've no doubt about being able to get other wheels to fit, however I am a stubborn and angry old man that is  currently having a toddler  tanty ... And I don't wanna get other wheels I want those ones!. ? ? as nobody else does wheels in that colour and style that I've seen before, so I want to get them to work, and as stated I am indignantly stubborn to the core so if need be I will over time and trial find a combination that works,but I would obviously prefer not to....

R34 GTT Sumotos. 310mm Rotor. R34 GTR Brembos. 328 (?) rotor.
R32 GTR Will fit. But you will need to sleeve down the bolt. 298 rotor (?)
No more tantrums today kids

R34 GTR 324 x 32

R32 GTR  296 x 32

Nope.  Brembo caliper 324mm rotors are only 30mm thick.

[oxford1327]

yep and at this point i have tried all of those combinations and to no avail....so the latest iteration is going to be the 355mm fronts and 330mm rears from a 370z with the Akebono calipers, and the only way to get those to fit still will be with a 15mm thick bolt on spacer on the fronts (rears clear no problem), with its own secondary stud set, at least that way they will become a semi-integral part of the axle and allow me to get the wheels fitted until i can source a compatible caliper and rotor combo that wont require the use of spacers and give me the desired offset etc.
