Greetings from England, I've just bought a 2013 Vantage 4.7 so I'm new to these pages, please be gentle as I ease myself in
Before switching from my TVR to a V8 Vantage I did research the cost of service parts and consumables and it all seemed quite reasonable, however, I've since discovered around 2012 Aston made the six piston Brembo front calipers standard fitment, this setup coming with the expensive 380mm two piece floating discs.
So while the earlier single piece 355mm Brembo (09.8780.21) front discs used with the four piston calipers are reasonably affordable at £150 a set, I'm now faced with paying a painful £750 for a set of the two piece floating discs. I have read in the following thread on Piston Heads that Aston reverted back to a single piece disc on the 2014 Vantage, and being 380mm with the correct depth these can be used with my six pot calipers?
I don't plan to track my V8V and would be perfectly happy with a set of lower priced single piece 380mm discs, so my question is does such an option really exist, or am I forced to suck it up and pay the £740 for a set of Brembo (09.B324.13) two piece discs?
Thinks, there a big chat rolling on FB re this one.
BTW its not £750 for a set of the two piece floating discs, that's the price for one!
Reusing my hats/bells and fitting new outer rotors would be the sensible option, but the fitting kit is not available from Brembo so if you break a spring clip or shear a stud you're screwed.
Apparently Martin from Reyland can supply a pair of discs and bells complete for £1,000, after that you're paying £540 for a pair of his outer rotors every 40,000 miles, I'm being told to expect 20,000 miles from a set of pads and 40,000 miles from the rotors.
Kind of wished I had the earlier four piston Brembo caliper setup with single piece discs that are only £150 a pair
My 2013 has two piece front rotors. I wasn't aware this was unique to 2013. I would think you could use a one piece from later years as long as it is for the 6-piston caliper. I wouldn't think they changed the depth of the caliper mounting, but you could check the specs to be sure. When the time comes I'll probably go with the two piece as it shouldn't be something that has to be replaced very often and the two piece is definitely an upgrade over one piece.
My 2013 V8 Vantage has same, 380MM rotors & 6 pot calipers have sports pack suspension & I believe when you have sports pack or S model they come with 2 piece rotors & 6pot calipers.
I saw that ebay listing too, but now days I don't trust any manufacturer, they have factories all over the world & I've seen big difference in quality when it comes from you know where...... It says it's Brembo, but where was this part made, I doubt that is same as original part from Aston...
I believe all cars after 2012.5 have the 6 pot calipers, regardless of S model or sport pack. You think Brembo makes rotors specially for Aston Martin? I doubt that. I'm sure this rotor is used on other cars as well and all Aston does is put the rotors they get from Brembo in an Aston box. I would have no issues using the Brembo rotors. You can debate where the metal came from and where the rotor was made, but for normal use it doesn't matter. Even for track use it really isn't going to matter other than maybe wearing faster. There's definitely a difference between an Autozone rotor and a Brembo, but I'm not going to worry about where the Brembo rotor was made.

I do this for living, I own of auto repair shop.
I've seen really crappy Brembo branded brake parts that are really awful. So you do what you what you desire, but I'm really carful what i put on my customer cars.......... I've seen $20 brembo branded brake pads...
it's your choice..
Here's what I've learned so far having discussed this subject with various Aston specialists here in the UK.
From 2012.4 the six piston Brembo calipers became standard on all V8 Vantage models
The six piston Brembo calipers use a 380x34mm disc (rotor)
There were two 380mm front disc (rotor) options used by Aston Martin
The two piece fully floating disc - Brembo part number 09.B324.13, this is by far the most common
The single piece so called 'Co-Cast' disc also produced by Brembo and thought to be fitted for a short period by Aston Martin around 2014, these discs are rare and its believed they may no longer be in production? - Aston Martin part number BG33-1125-BA - Unfortunately I have not been able to find the Brembo part number for the Co-Cast discs so if anyone can find this please add it to the thread
Obviously the two part fully floating disc is lighter but they are extremely expensive, the cheaper but slightly heavier Co-Cast discs will not dissipate heat as well as the two piece floating discs but they were used by the factory from 2014 on so were fully signed off by Aston Martin, its therefore more than adequate for road use. It looks like Aston worked with Brembo to create a more cost effective disc option for the post 2012.4 Vantage fitted with the six piston calipers, you can learn about Brembo's Co-Cast technology here:
Co-Cast is a sophisticated combination of metallurgy and casting technologies that brings together a steel hat with cast iron rotor, the concept was developed to offer a more cost effective option to the expensive to produce but best weight/performance two piece fully floating disc design that joins the steel hat to the cast iron rotor using threaded fasteners and spring clips. As such a Co-Cast disc can not be described as fully floating, but it does represent a best in class cost vs performance compromise when compared with the traditional two piece fully floating disc design used in motorsport and seen on many high end performance vehicles, the only thing better being carbon ceramic brakes that take things to the next level again.
Things to consider:
If you track your Vantage its advisable to pay the extra money and go with the two part fully floating discs
The Co-Cast discs are rare, just finding a set can be tricky
The Co-Cast discs (if you can find a set) are not cheap themselves, look to pay two thirds of the price of the two piece discs
The two piece fully floating discs should be rebuildable like any disc of this design, but Brembo have decided not offer the fixing kit, so you are forced to buy the complete factory built up outer rotor and hat at great cost
The fixing kit is essential as the existing fasteners and spring clips should not be re-used, the studs may shear and the clips can fracture leaving you with no other option but to buy the complete factory built two piece discs from Brembo
The readily available fixing kit produced in the UK by AP Racing is not the same as that used by Brembo, they are not interchangeable
Here in the UK I can buy genuine two piece fully floating Brembo 09.B324.13 discs from trusted German supplier Autodoc for £1,480.00 a pair, the important word here being GENUINE! The correct 'best price' for genuine two piece fully floating Brembo 09.B324.13 discs will always be in the order of £1,500 Sterling, if you are finding cheaper prices than this its best to assume they are Chinese Fakes!
The above eBay link where the seller is offering a pair of the two piece fully floating Brembo 09.B324.13 discs for $800 US looks way too cheap to me, either they are Chinese Fakes or the seller is giving them away for almost half Brembo's trade cost price which I'd say is highly unlikely. There is a supplier here in the UK also selling on eBay who has offered me a pair of Brembo 09.B324.13 copies for £1,000, while he tried to claim they were UK made the two week lead time he proposed sounds suspiciously like he's just ordering them in from China, I won't be taking up his offer!
Amusingly this UK eBay seller tried to tell be the metallurgy used for his discs is superior to that used by Brembo, I'm sorry but if you know anything about brakes you'll know Brembo are the world leaders in the industry and spend millions on R&D. To suggest his metallurgy was superior to that used by the mighty Brembo corporation was frankly laughable!
If you can find a set of Aston Martin part number BG33-1125-BA Co-Cast discs I have no doubt they will be absolutely fine for a street driven Vantage, however if you want the best and or you track your car, then it seems clear a genuine set of two piece fully floating Brembo 09.B324.13 discs is the way to go. Yes these discs are frighteningly expensive compared with the single piece front discs used with the earlier four piston Brembo calipers, but its important to acknowledge the Brembo six piston caliper and fully floating two piece disc setup used by Aston from 2012.4 are in a different league of performance.
Just watch out for the fake stuff, if you're finding two piece fully floating Brembo 09.B324.13 discs any cheaper than the equivalent of £1,480 Sterling a set you really do need to accept they are almost certainly Chinese copies. I shouldn't need to remind people here that brakes are a critical safety component, so you must think twice about fitting discs that are suspiciously cheap. Disc metallurgy is a complex science and Brembo are the trusted world masters of it, I've seen Chinese discs warp and crack after just a few heat cycles to it really is a case of 'Buyer Beware'!
I trust the above information is of help to others, this is my first post on 6speedonline and I hope to contribute to the community in equal measure to the intelligence I look forward to gathering here and will benefit from myself?

Here is a link to the 2-piece rotors sold directly from Brembo. $399.95 per rotor and free shipping. You are getting ripped off if you are paying 1500 pounds for a pair.
Indeed, I couldn't agree more, however I am also suspicious there is IP addresses tracking going on here as just clicking on your link redirects me to the European Brembo site, so I can't even see the more realistic North American prices here in the UK
I had assumed the eBay link above was for fake discs, but I'm now wondering if it's just that Brembo Europe are properly ripping off their UK customers? My eBay account tells me if I bought the discs from the North American eBayer partscontainer then I should expect to pay £647.89 Sterling including postage, even if I then get hit with 20% import duty that's only £777.47!!!
If these are genuine 380 x 34 mm OE Brembo 09.B324.13 discs, its a saving of well over £700.00 Sterling, that sounds almost too good to be true
I have to say I'm finding it very hard to believe a pair of genuine Brembo discs can find their way to the USA then all the way back to Europe, and with a US seller making a margin, with me the buyer paying half the cost of the cheapest vendor here in Europe (Autodoc).
Are we really getting that ripped off here in the UK, or are those eBay discs fakes?
I would be pleased to be proven wrong, but it all sounds a bit to good to be true?
All I can say is that direct from Brembo USA the discs are $400 each here in the US. The Ebay add is a little cheaper than that, but within the realm of possibility if they are getting them at wholesale. The company is called Newparts in the add and they claim to be an official Brembo partner. You might be able to somehow verify that with Brembo or you could just give them a call. They actually list a phone number in the add. They are on Amazon as well. They seem legit to me personally, but you have to decide.
It's quite possible the discs aren't made in Europe. That gets back to what 007jb said. I just put a set of Brembo rotors on the front of my STi and they were made in China. These were just your basic blank rotors and not 2-piece so hopefully a higher end rotor wouldn't be made there, but it's possible. Even if it's made in China you would like to think the metal and process for Brembo would be to their spec, but you never really know. If you aren't going to use Brembo then you have to find somebody else who makes the right rotor and then figure out where their rotors are made and out of what metal.

Is there a North American vendor of the single piece so called 'Co-Cast' disc also produced by Brembo and thought to be fitted by Aston Martin from around 2014?
The Aston Martin part number is: BG33-1125-BA
The best price here in the UK I've found for a pair of theses 'Co-Cast' discs is £900 a pair, given we are typically paying over the odds for our Aston brakes here in Great Britain, perhaps buying a pair of the above single piece 'Co-Cast' discs (BG33-1125-BA) from a North American supplier and importing them into the UK is the way to go?
Unfortunately I have not been able to find the Brembo part number for the Co-Cast discs, if anyone can find this please add it to the thread.
