Good pads, i.e Not Benshit pads, decent rotors such as DBA5000 or DBA4000, good brake fluid and it's more than enough.

For years I was doing track work with the stock brakes on a 372kW R33 GTS-t to give you some perspective - albeit it was a bit sketchy trying to shave speed off turn 2 at Wakefield LOL.

Another cheap option besides @Duncan's suggestion is finding a set of R34 GT-t calipers and rotors. They're 310mm, and still use the same DB1170 pad, but with the benefit of additional surface area. I would have recommended 350Z Track Brembos and rotors however it seems like everyone has caught on they can be made to fit the GTS-t so have rocketed in price (probably due to that article I wrote like 10 years ago) lol.

Hi all, thanks for your suggestions. This is what I have selected, what're your opinions?

Front: https://justjap.com/products/dba-4000-series-front-brake-rotors-nissan-skyline-r33-gts-t-sumitomo-type
Rear: https://justjap.com/products/dba-4000-series-heat-treated-rear-brake-rotors-nissan-skyline-300zx-sumitomo-calipers

Pads: DBA Xtreme Performance Brake Pads or something else (if anyone could help me find the compatible pad that would be great)

The problem I am having is with the brake calipers. Currently, my stock calipers are pretty badly damaged and would need a touch up if not a replacement. Problem is OEM replacement is over $1k-$2k each (compared to stock r33/r34 gtst rotors about $200-$300) each, so will have to buy some 2nd hand or if anyone had any aftermarket recommendations?

Well, price up discs + pads + calipers before you go down that path, it will really add up.

$2,700 for lines, pads, discs, new calipers - https://justjap.com/collections/attkd/products/attkd-brake-kit-nissan-skyline-r33-93-98?variant=42485721891015

Not exactly cheap, but good value, especially if you are trying to find 2nd hand r34 callipers

what is the issue exactly? pistons need replacing or bore is scored?

Yeah, I've seen that but for some reason thought it was only the fronts included. I think I'll end up just going with that kit and save myself the hassle of buying everything separate. And the fresh hardware is nice ahah

These are one of my brakes right now, I haven't looked too closely at the calipers but from the outside you can see they are pretty badly scratched up, and I am going pretty full-out on this build so may as well just get new ones.

Just to be clear - external scratches on a caliper are unlikely to be a problem. It does look like someone has ground off the Nissan casting and otherwise gone over them with an abrasive to smooth out a lot of flashing etc, then perhaps treated them a bit roughly on the car or kicked around a workshop floor.

Unless the material thickness is excessively compromised where the scratches are unusually deep, you'd just file them a bit smoother and paint them. I didn't even bother touching the R34 calipers on my car in any way except to throw some black paint on them. Because....they are brakes. They are for doing things, not looking at.

I'm running 350Z Track edition Brembo's with 324mm discs in front on my 32 gtst. I think the calipers were 250$ a pop new. See my link below for info.

I wrote this in a post not long ago but seeing as your question is a tad different:

I'm running the OEM R34 brakes for frequent track use with stock power. Have had them rebuilt, Dixcel Z type pads, slotted Dixcel rotors (this combo is noisy as sin) and Nismo braided lines - they're fine and hold up well, the engine begins to get into dangerous temp levels and I have to cool off before the brakes lose effectiveness. Also ran the car with oem pads, rotors, hoses, it also performed fine. 

My friend is running a 500hp 4 door R34 with the stock r34 brakes with good pads/discs and has no issues. 

As others have said, the r34 calipers have recently increased in price but probably are still cheaper than any alternative. From memory they're about 400USD in Japan.

      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.
