2 Piece Standard Size Discs For 32/33/34 Brembos

[Duncan]

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.

[Ronin 09]

yeah i was going to ask whether you should get a pair of hats made up to AP rotors?

they would surely not be too much more than what a Project Mu would be?

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

guys, duncan is talking standard BREMBO (ie 324mmX30mm) not standard 32 (296'ers).

[Duncan]

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

Whats the ruling on brake ducting for your category?

[Roy]

The DBA 5000 seem to be different anmals to the 4000s with none of the problems, well not that i have seen.

[djr81]

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.

[Duncan]

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 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.
