what the hell is AM doing?!
You buy a GT12 and then they go an offer the same power output to standard v12vs models??
Yes its still lighter and all that, but what the hell???!
Whats the point of paying the premiums to have the most powerfull V12 Vantage, and then get screwwed over by Aston like this and having STANDARD cars have the same power output.
What a joke.
This is so wrong!!!!!!!You buy a GT12 and then they go an offer the same power output to standard v12vs models??

As a GT12 owner, I am deeply disappointed. AM humiliated all GT12 owners with this kind of disrespect, I am utterly shocked!!!!!
Absolutely gutted.

Original is original - I wouldn't worry too much.

Surely you guys didn't buy a GT12 because it had 30HP more than a V12S? I would have thought the the exclusivity of a limited run more aggressively focused model would have been the draw. If was the HP, or even the sound you could have picked up a better performing fezzer for similar money...
Still, each to their own, and I guess ;-)

The additional 30 HP wasn't the only factor, but was certainly part of the reason why GT12 appealed to many of us.
Speaking of Fezza, they'd never offer a power upgrade on standard cars to match their top of the range models. This is what sets Chanllege Stradale , Scuderia and Speciale apart from regular V8s.

+1 Owning a V12VS with the "Performance Pack" and thus the same power output as a GT12 doesn't make it a GT12! The genuine GT12's will always be rare and special, and no amount of tweaks to a std car can ever change one into a GT12, even adding a horseshoe bonnet and all the other hundreds of bits. I wouldn't even like to work out how much the total cost would be by the time you add in all the bespoke internal and external CF bits.
Original is original - I wouldn't worry too much.

Adam, Thank you for the anger soothing comments.
Unfortunately it still doesn't change the fact that AM is making the best of its effort to clinch the worst marketing strategy title from Maclaren by pissing off its owners in the most disrespectful way.
Assume every V12VS owner generously upgrade their car to match GT12 output with relatively minimal cost, now the only thing differentiates GT12 from every other V12VS on the street (with respect) is the so called exclusive body kit (now shares the same design language with GT8). And of course the seemingly rediculous premium.
So what's next? A power upgrade for all V8 Vantage to match GT8 output? I'd be surprised if AM doesn't offer it in the near future.

If 592 bhp was 'certainly part of the reason', how do you feel when you meet the owner of a standard Aston Martin road car, with a 600 bhp engine?
Speaking of which, AM pulled the same trick by selling all moulds and auxilliaries to Strastones, technically all V8 vantage can now be converted into V600 LM spec including body kits.
I now share the same disappointment with the original owners whose kept their car up to the present.

The GT12 is still a world apart from the V12VS with the Performance Pack. The carbon fiber body panels cost a fortune, and there are enough differences throughout to make it a very different car.
From a straight "on-paper" comparison, it's easy to replicate the GT12... 30 hp is easy to find in the aftermarket, and losing 100 kg from the standard car isn't hard, either. 30 hp and 100 kg are easy to find, and for FAR less than the price difference going from a V12VS to a GT12.
Aston did the same thing with the V8VS and V8VGT in the US (not sure you guys got them). The V8VS was the most expensive V8V and had an extra 10 hp (woo, big numbers). Then they introduced the GT, which is the least expensive Aston ever (aside from the Toyota Cygnet), but had the same power and suspension as the V8VS (but without the carbon fiber or bells and whistles). They got the cost down by making everything optional and limiting build choices but *on paper* it had just as much power and weighed the same as the US$50k more expensive V8VS.
Not to mention when people bought a DBS for US$280-300k, only to have the DB9 run its underpinnings for US$200k at the end of the DBS's life (but still sold side-by-side for a time for those remaining DBSs that hadn't sold prior to the DB9's update).
For the price, there's no way the rear valance included with the GT12 Performance Pack will too similar to that of the actual GT12. In style, maybe, but it'll have to stay within the confines of the V12VS's rear bumper - only the carbon valance will be replaced, not the whole rear end, so you won't see Aston putting GT12 rear bumpers on a V12VS. Just my guess.

If I were a gt12 owner I really wouldn't worry about (and as a soon to be gt8 owner - if anyone wants to delete their secondary cat to match the power increase, good luck to them)
The GT12 is soooo much more than just an extra 30bhp and no attempt to recreate one, from an "ordinary" v12 will impact on that
For me it's very like db5 and db6 vantages vs standard cars. Everyone can pay to convert their engines from SU carbs to Webers. But unless the car was built originally as a Vantage by the factory it adds zero to their value

First, you have a splendid rare car. And just like I tell my partner, a fake Louis Vuitton bag does the same as an original is neither here nor there. You have the real deal and no one can take that away.
Second, to us original V12V owners who expected only a 1000 units to be made from 2009 on. Well look how that really turned out? ie Aston has form on this and perhaps one should calculate how this may roll-out with your value system and if one could be affected by any cosmetic upgrade or the next model variant shenanigans? I.e the GT12 Zagato S. with 5hp more under the hood and 9-speed box or whatever.
Finally, if I could, I'd send you a PM and take the GT12 off you. Unfortunately, I wouldn't be able to make you whole on that. Enjoy that great car you have.

As another poster points out, you wouldn't find Ferrari (or for that matter Porsche or Lamborghini who are both very fond of multiple special editions) offering a performance boost to their 'standard' model taking power up to that of their most powerful model. Having said that, you find the other manufacturers do far more to boost the power output of their trackday specials than change delete the rear cats & change the inlet manifold on the regular engine. Indeed I'm not sure any other manufacturer in the same area of the market would do so little to boost/improve engine as Aston has over the life of the current generation of cars
What are the other differences for GT12 over regular V12VS apart from the power/exhaust upgrade ? From memory, slightly upgraded brakes, wider track, lighter wheels, carbon trim to door panels & centre console and of course the aero......anything else of significance that affects performance/driving apart from optional plexiglass, seat electrics removal & even lighter wheels ? Am I missing anything ?
Porsche or Ferrari in an equivalent model, especially with that kind of price premium, would look at different engine mounts, proper changes to gearbox, completely new racing buckets, harnesses, etc - Aston put in fabric door pulls and make them out of the heaviest fabric imaginable (leather)......
One imagines the wider track and the aero are the areas that have the greatest impact on driving experience for GT12 over regular V12VS (I'm interested in GT12 owners' views on this), apart from noise of course, however anyone who has de-catted their V12 Aston can't be far off the noise of GT12 ?
Can't imagine for one moment this upgrade will have much effect on GT12 values or perceived exclusivity. But I'd also be annoyed if I were a GT12 owner....

I was considering a GT12 recently.... I know one for sale which is ALMOST in budget.
The reason I want a GT12: most powerful out-of-factory produced Vantage using a naturally aspirated engine EVER and probably last one.
I like that its limited to 100 units.
I like the agressive looks and CF bits
I like the aero.
I like it because its the best of the best that AM offer as their top range model.
Now....those idiotts go and offer the power upgrade to standard model cars.
Now no longer is it the best of the best in all fields for AM. It has a significant hared component with a standard car.
Imagine if you buy a 675LT and then McLaren offer the same power-upgrade to 650S drivers (I know its a bit more tricky, but for arguments sake lets believe it is feasible and offered).
Do you really think people would accept this kind of non-sense????
Paying the massive premium of owning a 675LT and then seeing standard cars match your poweroutput with a 13K investment?
At least McLaren screw you over only by creating a new limited model that is much alike the previous limited model. Aston do the same but on top of that offer the upgrade to standard cars.
For some magical reason AM gets away with this kind of non-sense.
EDIT: this is not about just the power output or future value. This is about AM selling something as their top tier product (of which hp is a part of ) and then for $$$ sake trying to make a few 100k extra with this upgrade. Someone needs to teach them the meaning of customer life time value. They are losing millions just to gain a few 100k extra. Idiots.

This power pack is very interesting but I have already gone a different route
for my V12V.
Interesting bit apart from Aston diluting GT12 'specialness' is the price, N400
/ AM power upgrade kit for V8 was 20BHP for approx £3000 whilst this is approx
30 BHP for probably + £15k when fitting and VAT is all said and done??!!
The route I took was primarily one of preventative maintenance, I wanted the
primary cats gone to avoid future failure and the expense of likely engine
rebuild after reading what unfortunately happened to CraigV12V's car - outside
of warranty I couldn't contemplate needing an engine rebuild. So for approx £2k
I got Bamford Rose to remove my manifolds, cut out the primary cats, rebuild
exhaust system and reinstall. With ECU reflash the power gain is Circa 40/50 BHP
and I no longer risk cat ingestion.
I suppose this GT12 power pack kit is OK for bragging rights at the bar and
upgrading whilst keeping warranty, but for the meagre £ per BHP ratio it's quite
ridiculous compared to what other hardware (Lance spec @ circa 80BHP for circa
£7500) can be found on the market - but I concede that if it's your sort of
thing, the rear diffuser and wing looks ok??!!
Considering the reasons why I did it and the power increase I received as a
pleasantly received secondary bonus, removal of primary cats is the no brainer
solution as far as I'm concerned.

How will it be at MOT time? ie any special measures needed or will it pass straight off with the mod?

It's logical as a consumer to look at £s vs power increase so no issues there, but in terms of £s for what you are buying physically, it's a different matterfor my V12V.

As with BR's 'full fat kit', the majority of the power kit's power increase comes from de-catting but the majority of the price is for something different
You can cut out the rear cats and replace with straight through pipes (as I have) for a few hundred pounds and get the bulk of the power increase on any V12V/V12VS
The main cost of the 'gt12 kit' is the titanium pipes, fitting, rar CF valance, etc plus of course the comfort of it being a factory standard item which no matter what anyone says, has to be, all other thing including price aside, more deisrable
