So....I need to give up on standard discs and move up to 2 peice ones. One major reason is overall weight (one piece discs are terrible) but also long term cost of replacement discs.

I can think of

DBA5000

Project Mu

Stoptech

Who else should I look at and who has actually used and has feedback?

At this stage I will probably go DBA due to price and availablility unless something else comes out of this thread.

Ok, from Japan you will also find you have

Biot

Endless

Apex (The only company I know of that makes off the shelf 2pce for the 296mm rotor R32 GTR)

If you look through the AP and Wilwood range I don’t doubt you will also find the correct sized rotors leaving you to go custom hats to suit.

You need to have a think about how much cooling you need for the rotors. The list varies alot in terms of how many internal cooling vanes the things have.

From the least:

DBA, Project Mu

To NFI

Biot, Apex.

To the most

Endless, Stoptech.

Oh and Project Mu make a 2 piece for the R32 Gt-R.

I have some Project Mus on my 32 (with Roys F40s & a 324 rotor). Comparing the Project Mu to the DBA gives a big tick to the mus on their metallurgy. I had far fewer problems with cracking, crazing etc with the Japanese stuff. Of the rest Endless is $$$'s, Stoptech distribution blows hot & cold (Sometimes it just blows but it may be good again). Can't comment on Biot or Apex.

If you are not in a hurry try Greenline. Also if you are not in a hurry wait for the Aussie dollar to recover against the Yen.

Shopping out of an AP or Wilwood catalogue makes it easier to decide on number of cooling vanes etc.

And good spot on the 296mm Proj U rotors that fit the R32 GTR, i never realised. Thats about the perfect upgrade for thge Silvia lads, 296mm is plenty of rotor up front, though the R34 310mm GTT rotor would be ideal budget banger setup and 17" wheel combo

yeah sorry I did mean 324 not 296. The discs have to be standard dimensions (324x32) or within 2mm from memory

At this stage I am happy enough with the stock rotors and don't want to spend more than I have to. Thats why I was tending towards the dba gear....and I was really wondering if anyone has used them and had problems with cracking or otherwise in the 2 piece range.

Not too keen to stuff around with custom hats unless there is good support locally for a brand when I need support/new parts in a rush. Nothing worse than rotors I have to wait 8 weeks for

Sorry I should have been clearer. What I wrote other than one line, related to the 324*30 rotors.

If you are just going to get standard rotors & are ok with cooling then Project Mu take alot of beating. Otherwise I would go and spend large & get some Endless stuff.

Delivery was only a few weeks ex Greenline. Price was (in Yen)

Project Mu SCR Pro (Front) 324x30 8 slit type R32 GT-R V-Spec (Brembo)

1 60,638 60,638

Shipping: 22,900

Total: 83,538

Shipping was probably more expensive & a little slower for me because unlike most of the country I don't live in Sydney and/or Melbourne. They send you tracking info etc so you know where you stuff is at any one time.

They are also available locally (Racer Industries) the brake bloke there is helpful & knows his stuff - just not sure of the price.

Why don't you buy a pair of complete hats/rotors etc of whatever type & then also get a spare pair of rotors. Or better yet a complete set so your race day isn't ruined by a busted brake rotor.

As for DBA I have reached the conclusion that the problem with them is mostly centred around the DBA4000 series & at that rotors for the R32 GT-R. Like Roy says the 5000's appear to be ok. But for my 10 cents worth seeing as its brakes we are talking about I would be looking for more than just ok.

I have std sized dba5000's on the front of my 33GTR...have stood up well to a lot of abuse (I'm pretty hard on brakes) with only surface cracks to show for it.

Ben, no brake ducting allowed unless it was standard. And thanks Mr Nissan, the 32 N1 had rubber brake deflectors mounted on the castor rods :D They cost a bomb for genuine but I couldn't go past them

Thanks for the prices djr, I spoke to racer industries and they quoted a very similar price for a pair of project mu, 1400. I had a good look at the vanes too there was nothing tricky in there (ie no curved vane or anything like that).

I wish I was allowed to run my G4 brakes but they are 330 not 324. The more I look at them the happier I am.

Autobarn quoted 630ea retail for dba5000 slotted and about 420 for discs only (no hats). I'll talk to racebrakes this week but I'm pretty sure I'll go with the dba gear.

      3D printing fun

      No worries at all 🫡 I think the most satisfying things to make are the little bits that are just impossible to find or they're no longer manufactured. Generally I always try to replace parts with OEM wherever possible. This little project is also great because it'll never see the light of day, but strengthen these brackets so it's not just relying on the little standard screws in the headlight plastic. As soon as I saw the standard brackets and screws I thought, "well I'm not going to install with just the screws, the plastic tabs will just snap off". It's crazy how expensive everything has become yeah. But I suppose that's supply and demand; granted it's a lot easier to get brand new genuine parts these days which is fantastic 😊, I don't have to get totally reamed at the local Nissan dealer ha ha We sure are lucky we have all these manufacturers making parts these days, a few really great Australian companies too like Platinum Racing Products and Fit Mint Automotive, what a time to be alive ❤️ . I've got my eye on the RB26 head by PRP as mine has a very fine hairline crack, so that'll need to be addressed some time in the future. If you have any requests or odd things to make feel free to let me know and I can have a crack at making replacement parts ✌️

      Thanks for sharing this, and BTW if your headlights are in good condition they are worth thousands....you might want to consider replacing them with brand new LED ones like this (https://www.nengun.com/78works/full-led-headlights-r32-skyline) and making enough profit to buy a house in Sydney

      R32 GTS (RB20DE) clogged cat

      By Duncan · Posted

      I'm not sure what sort of shops are nearby, but I'd expect any reasonable exhaust shop could put a cat in it that will not restrict the power that engine makes. Otherwise, if you want to remove it, short lengths that replace the cat are readily available online, search for "de-cat pipes" or "test pipes"

      Howdy friends, So another weird one today, I was looking into replacing some broken clips holding the front grille for the R32 GTR (part number 01553-03831), and noticed the brackets which are supposed to hold the grille in place were also missing 😑. I do recall seeing this issue many years ago, but didn't fix it at the time. A quick look on eBay and I was able to find the genuine brackets, along with all the screws which suited the headlights (part numbers 26042-08U05,26092-08U05). Happy days!....  Once they arrived however there was an extra nut in the packaging which implied that there should also be a bolt or a stud, and sure enough, after a bit of searching I found this thread from 2013, and @Ants clearly shows a stud should be present. Reading around a bit more, it's possible the headlights on my car are the "povo pack" headlights as mentioned by @funkymonkey in this thread way back in 2008. This could explain why the studs are missing on my set of headlights. Looking at the headlight diagram I wasn't able to see a suitable part number for the stud itself. The headlight did indeed have a recess that looked like it would accept a stud, but interestingly no thread or anything obvious how the stud would be affixed to the headlight, I suspect it may have been glued in, press fit, or melted into the plastic at the factory. Another member may be able to clarify if they happen to have a genuine set of N1 headlamps. The only thing we have to work with within the recess is a keyway which likely is there to prevent the stud from rotating within the recess. In any case, back to 3D printing, I put together a model which acts like a pug with a friction fit inside this recess, making use of the keyway so it doesn't rotate while tightening a bolt. Printing in TPU will allow it to slightly swell making a nice snug fit without cracking the part. I've designed the adaptor it to accept an 20 mm M6 bolt (stainless with a cap head in my case), as opposed to the standard M5 stud and I made use of the standard galvanised split washer that came with the genuine brackets from Nissan. Once the bolt and screws were all in place, giving the bracket a gentle shake gave the classic "shaking the car" feeling, very solid, which gives me confidence this is going to be able to hold on much better than the janky solution which seems to have been here for the past decade or so. Overall I'm really pleased with how this turned out and maybe there are more people out there running these headlights without a centre stud at all!

      R32 GTS (RB20DE) clogged cat

      By GabsReDeal · Posted

      Hey everyone, This is my first post apart of the introduction. I tried searching a bit on the forum but couldn't really get a straight answer. I got the car to my mechanic as I felt it being weak. It seems that it was missing on two cylinders due to the injectors. I had all my injectors clean and the car runs much better. The mechanic also confirmed my suspicions that the cat is clogged and needs to be tackled asap. The cat rattles a bit and the hot exhaust warning frequently lights up when driving after getting the injectors clean. In my introduction I was asked about what modification I might be interested in and mentioned a cat delete. From what I was told, this is not really beneficial on the RB20DE and there are more cons than pros.  Could perhaps anyone give some suggestions on what the best course of action would be since the current cat is toast and needs to be removed/replaced anyway? I can also sometimes smell a strong smell of fuel, but I'm not sure if this is related.
