wouldn't the bias go the other way though? bigger piston means less force on the rotor for the same pedal pressure (force = pressure/area) - so you're getting more clamp on the rears causing them to lock and trigger the ABS?

An aussie company Alpha Omega already produce brackets to fit Evo X calipers & rotors to S / R / Z chassis cars, $350 a pair. http://www.ao-ps.com/brakes.php

Problem i have is the abs kicks in way to soon even tho the brakes have much more left in them,

Not a problem with your ABS but rather your choice of caliper!

Why I have never liked this option as an upgrade. If you don thave ABS you would think the setup is crap. ABS in part masks how badly balanced the setup would be with EVO calipers....but will always make the ABS have a heart attack simply because those calipers and rotors will cause the brakes to lock sooo easy

Oh they are quite an improvement and work very very good when you combine them with gripy semis, shitty road tyres will see your abs going skits unless you improve the rear brakes, even if its just slotted rotors and good pads to help even out the brake bias

I was about to do this upgrade when I found a Nismo 355mm brake upgrade, I have fitted the front without doing anything to the rear and with Hankook RS3s on the street hard braking sees the ABS kicking in, the Nismo instructions says this will happen if you don't upgrade the rear with at least better pads :)

I am looking into an upgrade for the rear using a factory Nissan 350 x 20mm disc with the factory GTR brembo :D

Im about to put evo calipers on my HR31 with 33R rotors, only reason I didn't go to the 350mm rotors is because I would have to upgrade to 18 inch wheels. Topped off with PMU HC + pads and dba slotted rotors I think these will be more than enough to pull up the old girl.

For anyone looking for calipers I got mine through Streeter delivered to SA I paid just over $500 AUD. I need to put new seals through them and repaint them but still fall cheaper than some of the ones I have seen on ebay etc.

Im hoping the local engineer shop will be able to hook me up with adaptors for a pretty little penny.

Hope you have ABS. Either that or I hope you dont tail gate as first time you have to stop in an emergency I am betting $100 you will lock up and sail into something you dont want to hit

Your car will seriously stop MILES better if you get R32 GTSt or Z32 300ZX calipers and run them on a 324mm rotor. Actually, an R34 GTT setup with a 310mm rotor would probably be better again!

If you must run the EVO Brembos then all you are going to need is something like a basic Bendix pad. A high performance pad like PMU is only going to compound the problems of locking up

I'm actually running the alpha omega kit on the front with the Evo 350mm rotors. I haven't tested

Them on the track yet but in terms of feel and stopping power on the street it has been a massive improvement over my 32 brakes.

I'm also running endless mx72 pads.

In terms of rear braking, if I was to upgrade to a 4 piston 330mm set up, would that be overkill in regards to front/rear bias?

Can you go into a bit more detail? BE greatly appreciated.

Have you run the MX72 pads before? What pads were you running on your old original R32 brakes?

So you have not tracked it but sounds like you have driven it plenty on the street. Do you have ABS? You have uber power so guessing you have used them for hard stops? If you have ABS does it kick in far earlier than before? What % increase or decrease do you have in pedal effort to stop the car in general driving.

LOL, lastly what BMC are you running ... sorry about all the questions

yeah.. the ABS n Evo's can pose a problem then >_<. isnt there a master cyl that you can use and adjust to prevent the lockup?

Sure the BMS has a part to play, but I think the bigger issue with the difference between EVOs and Skylines is probably the pedal ratio. It is really the only thing left that would allow for why EVOs can run such massive caliper pistons and not have a binary brake pedal. So if you must run the EVO brakes on your Skyline I think it would be wise to invest some time in trying to dumb down your pedal ratio

What ever size this sucker is

The Evo brembos are 4 pot

2x40 and 2x46 mm pistons on 350mm rotors

Looks the goods mate, might make your pedal a little softer but thats an easy fix

      Cheers. Skyline is back on the menu, can’t get rid of it. It’s like a child you don’t want, or herpes

      I got back to Japan in January and was keen to get back on track as quickly as possible. Europe is god-awful for track accessibility (by comparison), so I picked up a first-gen GT86 in December just to have something I could jump into right away. The Skyline came over in a container this time and landed in early January. It was a bit battered after Europe, though—I refused to do anything beyond essential upkeep while it was over there. The clutch master cylinder gave out, and so did the power steering. I didn’t even bother changing the oil; it was the same stuff that went in just before I left Japan the first time. Naughty. Power steering parts would’ve cost double with shipping and taxes, so knowing I’d be heading back to Japan, I just postponed it and powered through the arm workout. It took a solid three months to get the car back on the road. Registration was a nightmare this time around. There were a bunch of BS fees to navigate, and sourcing parts was a headache. I needed stock seats for shaken, mistakenly blew 34k JPY on some ENR34 seats—which, of course, didn’t fit—then ended up having the car’s technical sheet amended to register it as a two-seater with the Brides. Then there’s the GT86. Amazing car. Does everything I want it to do. Parts are cheap, easy to find, and I don’t care what anyone says—it’s super rewarding to drive. I’ve done a few basic mods: diff ratio, coilovers, discs, pads, seat, etc. It already had a new exhaust manifold and the 180kph limiter removed, so I assume it’s running some kind of map. I’ve just been thrashing it at the track non-stop—mostly Fuji Speedway now, since I need something with higher speed after all that autobahn time. The wheels on the R34 always pissed me off—too big, and it was a nightmare getting tires to fit properly under the arches. So I threw in the towel and bought something that fits better. Looks way cleaner too (at least to me)—less hotboy, less attention-seeking. Still an R34, though. Now for future plans. There are a few things still outstanding with the car. First up, the rear subframe needs an overhaul—that’s priority one. Next, I need to figure out an engine rebuild plan. No timeline yet, but I want to keep it economical—not cutting corners, just not throwing tens of thousands at a mechanic I can barely communicate with. And finally, paint. Plus a bit of tidying up here and there.

      Nope, needed to clearance under the bar a little with a heat gun, a 1/2" extension as the "clearancer", and big hammer, I was aware of this from the onset, they fit a 2.0 with this intake no problems, but, the 2.5 is around 15mm taller than a 2.0, so "clearancing" was required  It "just" touched when test fitting, now, I have about 10mm of clearance  You cannot see where it was done, and so far, there's no contact when giving it the beans Happy days

      It's been a while since I've updated this thread. The last year (and some) has been very hectic. In the second-half of 2024 I took the R34 on a trip through Germany, Italy, France and Switzerland - it was f*cking great. I got a little annoyed with the attention the car was getting around Europe and really didn't drive it that much. I could barely work on the car since I was living in an inner-city apartment (with underground parking). During the trip, the car lost power steering in France - split hose - and I ended up driving around 4,000kms with no power steering.  There were a few Nurburgring trips here and there, but in total the R34 amassed just shy of 7,000kms on European roads. Long story short, I broke up with the reason I was transferred to Europe for and requested to be moved back to Japan. The E90, loved it. It was a sunk cost of around EUR 10,000 and I sold it to a friend for EUR 1,500 just to get rid of it quickly. Trust me, moving countries f*cking sucks and I could not be bothered to be as methodical as I was the first time around.
