Any recommendations
Yes. Don't do it.

2-3mm spacer would be ok, any more you need hubcentric but you need to be sufficiently wide to enable the clearance on the centre to give enough material to be strong enough to safely hold the weight of the car. Once that has been sorted you need to change the securing stud/bolt lengths as the originals will be too short. Personally just buy wider wheels with the correct offset to fill the arches
But I like the standard look wheel. I'm happy to go bolt on hubcentric ,I've used them before with no problems ds666 said:
Care to explain why ?
Top of my head:- Wheel bearing life (increased moment)
- Increased understeer (agreed, not much though - caused by lowered roll centre)
- Altered effective spring rates
- I believe Aston wheels are hub centric
- Reduced wheel clearances (agreed not a major issue depending on the spacers used, unless you have to be able to use snow chains)
Loads of us have rear wheel spacers on our gen 1 Vanquishes .
None of the issues you mention have been an issue
Roll centre ? How’s that affected by spacers ?
Bearing wear - unless it was dramatically different after spacers how could you tell ?
Understeer - maybe …
Loads of companies making wheel spacers suggest little issues .
Spacers on the front are a different matter …

Lots of nonsence as per usual. any changes to any of the dynamics will be very very minimal
You can put a 5mm on no problem, probably 8 at a push before you run out of centring, past that as others have said you need to put bolt on adaptors which mean you need to cur the studs as they are knock ins.
If you want to revert to standard after doing it you will need to remove the bearing and knock the studs out and replace. The replacement parts are for transit twin axle studs (60mm) in m14 x 2.
you will slightly increase the scrub radius at the front and slightly reduce the wheel rate but it will be fractional and likely unnoticeable.
Aston martin fitted lower offsest wheels on the GT4 using the stock arm length and king pin and didn't feel it was a significant issue.

Fine, but the OP asked a question about Vantages not Vanquishes. None of the issues you mention have been an issue

Moving the wheels outboard increases the track width of the car. The increase in track width also lowers the roll centre of the car

Your rear wheel bearings would have a shorter-than-expected service life. A lot would depend on how over-engineered your particular rear hubs are (as Aston tend to raid other companies' parts bins) and how the car was driven, as bearing life (assuming no external factors like water or contaminant ingress) is directly proportional to load and number of revolutions. ds666 said:

This is actually linked to the roll centre issue, mentioned above.ds666 said:

Companies that try to sell something suggest that there are few issues with their products? I'm shocked.ds666 said:

Well, we are in agreement in that the potential effects on the front axle are far more significantSo, in summary. OP asked for recommendations, so I gave my opinion. You asked why, so I gave you my reasons. You didn't like some of my my reasons; I've now given you a more detailed analysis. I'm not a suspension engineer so if anything I've said is incorrect then by all means provide correct information. Aston engineers spend considerable time and effort selecting and testing components so that they perform to target: without knowing how close to the limit their final design solution was you have no idea what effect slapping on a set of after-market spacers will have so, in my opinion at least, it's best to stay with their answers. But, Hey! It's your car, so you do you.

Unless you go daft with spacers on width , all the points you make are " in the margins " and most people would notice little difference in either performance or product life.
True, but you could also say the same thing that you'll barely notice any aesthetic change either. Not that there are any issues with the wheel width as they left the factory for most people.Sooner or later these cars are going to climb back up in value, but it will be the ones that haven't been bodged about and are still in OEM spec and condition that will be worth the most.

On the Vanquish the rears are so inset they look like a Commer van ...
There is a fair amount of room round the Vantage wheels - it could really do with being lowered to improve the look , but is low enough as it is ...

Good man !
The middle pic looks like they stick out past the wheel arch ?
Yeah....isnt that an MOT failure...if they stick out too far?The middle pic looks like they stick out past the wheel arch ?

I left my wheel spacer days behind with a Talbot Sunbeam. It had bolt-on spots from Halfords, gooseneck map-reading light and fluffy seat covers too
