Will v12 wheels fit on a 4.3L 2007 vantage
Discussion
Good day to all of you,
You have been of very sound advice in my project to improve the looks of my old 4.3L, so here I am again with a new question. This time it is on alloys. I am very fond of the amv12 alloys and would like to know if any of you have fitted them on a 4.3L.
Are they direct bolt on ? Not requiring any spacers or other mods such as brake discs ?
The use of the car is purely road driving, with no track driving.
It is a project, if possible, I'd like to move on with quickly and hence would appreciate your kind feed back.
Once all the exterior mods, my aim is to work on the engine to give it more torque in the low range (cf bamford rose) and eventually if possible, upgrade the sportshift gear box so that it becomes a real sequential gear box.
Thanks in advance for sharing your views and better, your experience

From memory, the V12 wheels will fit the V8, but V8 wheels will not fit the V12 due to clearance over the CCM discs.
I'd ask Bamford Rose to confirm, or wait for someone who has done it!
I think if it works, the 19" wheels will look better than 20" on the short-wheelbase car. 20" do seem a little on the big side, I can >just< about get away with DBS wheels on a DB9, 20" car designed to work with all that extra bolt-on bodywork.
Only just though, George still thinks it looks wrong

Please post your findings here, I too have been pondering this question ever since I realised the V12V has 19's on it. There is a guy on 6speed who has put them on a V8 with no problems reported as I understand it. The V12 ones are wider, but there is not a huge amount in it ...

Hi Lewis, just laid my hands on a set of early DBS 20" to fit to my DB9,did you stick with the DBS tire sizes,or what would you suggest?I'd ask Bamford Rose to confirm, or wait for someone who has done it!

My wheels came with the DBS Pirellis on them, drives beautifully with a useful increase in grip. Traction is improved both under braking at the front and under acceleration at the rear, a HUGE improvement in fact! DB9 rides so well that the reduction in sidewall isn't really noticeable. Might be worth having a punt on Michelins though, I may have a look next time. Will get some new shoes all round for the Geneva trip
If you do, please report back...A.M. definitely state the wider V12 wheel should not be fitted to the standard car, I have popped a link to an earlier thread below, where I posted their full response along with details of what has been modified on V12V to allow fitment of the wider wheel/tyre."......

Having said this I would guess much would depend on how you drive the car and the demands placed on the suspension that could cause potential issues with tyres fouling etc. There is also a middle ground with the V8S/12.25MY Vantage wider tyres/wheels, which should be ok.

You've got a few links to go at there
One other thing that gets overlooked is the offset and width of the alloy
I've no data on the V8 alloys vs the V12 or DBS alloys but it is a common problem in other RWD cars
Here is a useful calculator once you have the data

If you have the DB9 wheels, why don't you put them on your car and see if they fit. Or do you not have them?
If you don't, I have a spare set of 9 wheels with 235 front and 275 rear, I also have a second spare set of wheels with 255 and 285 tyres on. If you want to drive down to the West Country we can try the wheels for sizing. (Just in case anyone is wondering the wheels are not for sale - I just don't mind helping a fellow AM owner)

Hi Maverick
I currently have the V8 10 spoke "spider" alloys. They are 8.5" * 19" Front and 9.5" * 19" and I have fitted them with 245/40/19 Front and 285/35/19 without any issues
What I'd like to do is fit the V12 alloys on my V8, which implies fitting 255/35/19 Front and 295/30/19.
However, I don't know whether this will fit

Mikey, thanks for the link....but honestly...I'm not sure I know what to do with it....It's all "chinese" to me....
Getting wheels & tyres to fit a car is not just about tyre size.
The width and offset from the hub have a larger affect this often varies between models
So the idea is you get the V8 alloy width and offset and compare it to the V12 alloy width and offset
That will tell you how far out they are.
This is one of the reasons people fit spacers, to correct the offset difference.
Many people got caught out on the S2000 with this (including me
)WOW have I been where you are now.
The 255/35/19 fall onto the front of my DB9, and If I tried I bet the 275 would go on as well (Havn't tried it). I am guessing you really want to put 295/35/19 on the back. But you can't find 35 pofile tyres can you? Only Michelin do that and they are hard to get hold of. However the 295/30/19 are a stanard well known size and are readily available. 295/30 are closer to the rolling radius of the standard 275/35/19. bad news I'm afraid, the 295/30 will not fit on the standrad rim. the reason being is that the profile is too low and the flexibility of the wall of the tyre won't fit the wheel.
Try putting the tyre size in the internet tyre calculator, it keeps throwing it out.
You can't jump to 305 because its just to wide, so 295/35/19 is the biggest you can use. 295/30/19 won't fit the wheel. The 285 fall inside the heel arch and if I'm honest you could easily fit 315 inside the wheel arch, but you would need to change the wheel.(I have not tried that).
I went right into different tyre size combinations. I only have a DB9 and NOT a Vantage.
Remember to tell your Insurance Company, they will do nothing, but you are covered. Have an accident without having told them and watch them wriggle.

Hi Maverick,
I will be changing the current alloys for Front 9" * 19" and 11" * 19", which are that fitted on the V12 Vantage
I would also change the tyres to that fitted as standard on the V12 (Front 255/35/19 and Rear 295/30/19)
Using the calculator, I am within the +/- 2.5% range and the impact on the speedometer is max 2km/h
Why I don't know is whether this V12 (alloys + tyres) combination can be mounted on a 4.3L V8.
Offset and other points are chinese to me. I'd google this to find explanations.....But the more I read....the less it makes sense.....
So now that I am really in the fog, and can't obviously ask Aston Martin dealers for help,....I'm definitively counting on forum members to guide me in the right direction

Hi,For the record, I currently have 245front and 285 rear on 19" and haven't experienced any issues
original 19-inchers are 8.5J 235/ 9.5J 275.New 8.5J 245/ 10.5J 285 feature on the latest 2012.25MY Vantage/V8S. The original V8V Sports Corsa tyre option (now discontinued) was this size, so they "should" be ok.
But the V12V has 9J 255/ 11J 295.
I have no doubt they will fit, but officially it is a no-no, although Mike will know what the likelihood of "real" day to day issues are likely to be.
This was on the earlier link, but I thought it was worth reproducing as it is A.M's official line on fitting V12 wheels to a standard V8, also an insight into what they changed on the V12 -
"Under no circumstances would we advise the fitting of V12 Vantage wheels to a V8 Vantage, as also the geometry, and braking systems together with the items below are engineered specifically model to model. Please rest assured any wheel and tyre combination offered by us as an option or accessory fit would all have to meet with engineering approval and sign off."
Rear tyres will potentially foul on:
-Rear springs in rebound (damper travel reduction and rear spring package change for V12V)
-Fuel filler neck during compression travel. (fuel filler was re-engineered for V12V)
-Rear wheel arch liner during compression travel (arch liners were re-engineered for V12V)
-DMTL bracket during compression travel. (DMTL was moved for V12V)
Front tyres will potentially foul on:
-Front wheel arch liners during compression travel (arch liners were re-engineered for V12V)
-Lower control arm on steering back lock in rebound travel. (rack travel was restricted for V12V)

Hi Grant,
Thanks for the heads up on this one. AM is indeed adopting a very conservative approach, as cars might be pushed to the extreme, on tracks or elsewhere. I'm not playing on these grounds, but rather looking for an aesthetically improvement, with a week end driving on B roads.
Thanks to BingoBob, I got the new & old offsets on my V8 / V12 rims
2007 V8 stands at Front 19*8.5 offset 46mm and Rear 19*9.5 offset 59mm
V12 stands at Front 19*9 offset 51mm and Rear 19*11 offset 68mm
Pluging this on the wheel offset calculator provided on this thread, I come out with the following results :
Front : inner clearance 11mm less and outer position extend an extra 1mm
Rear : inner clearance 28mm less and outer position extend an extra 10mm
But what do I do with ?!!!!!!!?

I need to qualify what I was playing with. I was using the OEM wheels and putting different tyres on. changing the wheel opens a whole new can of worms, with offset etc. If you're working within certain bounds then people have already done it etc. If you are sticking on much larger wheels, then you are changing the dynamics of the car.
Yes there are all the off-set gumph to take into consideration, but you need to look at the weight of the wheel as well, not to mention the geometry of the front and rear. The car will drive differently.
I once read an article about Jaguar and how they spent hundreds of thousands of pounds on developing wheel / suspension / tyre cominations spending weeks and months developing and fine tuning all the elements to work together, only for someone to come along with some £400.00 cheap wheel combo and you throw away all the research they did.
If you change the wheel, is the weight the same, is it lighter, heavier? Is the track the same as the original track? offset and the tech set-up of the wheel? Tyre pressure, what pressure do you put in them? The same pressure as the V8 or the pressure of the V12? Or are both now wrong and you need your own pressure.
I think a lot of people would say, "don't do it", personally I'd say, reasearch anything you want to do. It's not as impossible as you think. I rememebr I emailed Aston Martin Racing and asked for help about sizing etc. What they said was, ..... bugger all ...... they never got back to me. So you're on your own, sorry.
If they are racing with much bigger wider wheels, and I'm guessing the race cars have the same suspension, then they must fit. It's all according how much you want this thing.
