Hi All,

I'm about to upgrade the front brakes on my R32 GTR and was seeking some advice. I have done a search and read through various other threads on this forum. My car has 18" BBS rims on it and currently runs stock rotors & calipers. It does have braided brake hoses and I use good brake fluid. I'm looking to spend about $1500 including pads. The car is used mainly on the street with occasional track days.

Everywhere I look seems to offer DBA, which I don't really want (I'm unconvinced by them). I would love Porsche GT3, Brembo, AP, or Harrop but all are out of my price range. Any suggestions?

I have looked at Unique Autosports, Racebrakes, DBA, and all the sponsers sites listed on this forum. All only offer DBA below $3000 except the yahoo japan site but I can't read Japanese so it means very little to me.

Don't want to rain on your parade, but for the kind of money you are looking at you will only really get new pads & new rotors.

The DBA 4000 series rotors are a good thing. They are slotted, heat treated & marked with thermographic paint. Shop around & try to get a good price.

Unfortunately an upgrade to second hand Brembos will be about $2000 for the hardware.

Everywhere I look seems to offer DBA, which I don't really want (I'm unconvinced by them).  

Let's see if I can convince you............

We have 5 cars in my family fleet, all but one has DBA rotors (it's still under warranty).

We have 7 cars in the race team, all but 2 have DBA rotors. They had to have special rotors machined up using AP Racing blanks. If there was a DBA rotor the same size I would by them, same quality less than 1/2 the price. We use DBA4000's on the road cars and DBA5000's on the race cars. Even after a 20 minute race they can still lock the brakes, which means the tyres are the limiting factor in braking not the brakes themselves.

We have never had a rotor failure, we just wear them out.

On to the other parts of the braking system...............

The main problem I find with R32's is, due to their age, the callipers need servicing, this affects their clamping ability and consistency. For a bit less than $400 you can get a full service, new seals and pistons (if necessary) on the callipers.

Brake pads, there are litteraly thousands of choices. We use Bendix Ultimates on road cars and Hawke carbons (blue compound usually) on the race cars. Plenty of others will have other preferences to suite their individual application and driving style. No matter what brake calliper and rotor you use there will be a choice of brake pads, the more unique the calliper, the smaller the number of choices.

You have already done the brake hose upgrade to braided, which is well worthwhile on R32's due to age. They are similar prices to new rubber hoses from Nissan anyway.

Lastly brake fluid, regardless of the choice of brake fluid it must be changed regularly. Most of the problems I have seen (road and race) are caused by brake fluid past its use by date. We use Castrol SRF, extreme performance, silicon ester based brake fluid with a very high boiling point. When you get the callipers overhauled, start using it from then on as it is best not to mix it.

That will have spent a bit less than your $1500 budget, everything will be as new, and you won't believe the improvement.

:)

Thanks for your responses. I should have added some info...

I currently use Bendix Ultimate pads and recently had the rotors machined and the callipers sercived (about 1100kms ago). The brake fluid was replaced at the same time. I need to replace the front rotors on my white GTR, but figured I'd just swap the rotors from my grey GTR and replace these with larger discs (to fit under the 18" rims). I was intending to continue with the standard callipers, if possible, and only upgrade the rotors.

Every place I go to seems to only sell DBA. I've seen RBA, and Profex (I think) but these were cheaper options to the DBA. Surely there are brands of rotors out there other than DBA for R32 GTR around 330mm for $1500.

unique autosports have a kit from memory is around 800 dollars. it has 324mm rotors and brackets to mount the stock calipers in the right spot.

maybe send them an email or ring them. tell John the beer baron sent you!!

Again I'm only getting DBA as an option.

If you are set against not using DBA then you could source some project mu rotors or some endless rotors. they both make discs in standard 32GTR size.

try www.musecret.com.au and go for the project mu SCR PRO 2 piece rotors. that's what I would get.

You could always get Race Brakes Australia discs (IIRC they sell their own). I think Roy is a big fan of their products.

Out of interest, what do you dislike about the DBAs? They only problem I have ever heard of was one of their rotors fracturing on Targa Tom's car, and the DBA guys were very quick to replace and try and find the cause.

Lucien.

Thanks again Beer Baron.

I've checked out www.musecret.com.au and sent an email to Andrew regarding the SCR PRO two piece rotors you mentioned.

This is what I'm after... CHOICE! I like to consider all options.

I have no personal experience using DBA, I've read reports (mostly +ve, some -ve), and seen images.

Leon from www.musecret.com.au responded that the SCR PRO two-piece rotors for the R32 GTR are $1050 + $70 shipping. I'm getting confirmation on the size. Has anyone used these and able to provide some feedback?

I'm going to look into that, DBA4000, had them on my GTST all the way round. sweeet as and no probs

but I'm going to email and as about stage 1 with DBA 5000's. I've heard they are good. and I wonder if they are any cheaper then MUSECRET ones? made here in aus so maybe

thanks for the info guys!

Whydo you guys want to change calipers, the standard ones are fine unless you have a very quick track car....

Have you checked Sydneykid's suggestions above I'm sure they will give you the braking you need.

im just curious because i've driven about 15 different R32 GTR's this month trying to find my new car and they all seem to have very...'weak' brakes. what i mean is, the cars stop fine, but really need quite a lot of pressure on the pedal. i have just come from driving a 04rex so i'm guessing a more advanced power assisted brake system is whats making the difference?

or all the GTR's i've been driving need new pads and rotors and caliper rebuilds????

dan

well my front brakes were crap when I got them in too, remember you are buy a 10-15 year old car.

Now its got new discs, pads, good fluid, new brake lines and reco calipers it stops brilliant ;) If you still have problems after all that try a new master cylinder.

The GTR brakes are fine when they are working OK ;)

For better pedal feel you can bore out a R32 non-abs master cylinder and fit a larger Z32 piston. Then buy the non-abs brake lines from nissan that bolt straight on. Easy!

    • 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.
