I know there are lots of posts and videos on this site and PistonHeads about jacking up your Aston and I have looked at all of them several times but when I came to put my DB9 up on axle stands this afternoon, for the first time, I ran into a dilemma. The front location is not a problem ... the official jacking point has a bare metal area that my axle stand will fit on with no problem.
But the rear location is much narrower. If I was to use the designated area, only half of my jack stand would make clean contact with the frame; The plastic sill infringes on that area and would not create a stable platform in my opinion. So does everybody just move the jacking location forward a few inches and get the entire contact area on the plastic surface? I suppose I could Dremel out a larger "window" in the sill to allow my jack stand head to fit on all metal! Eeeek! Forget I said that!
I think HSM's jack pads are looking more appealing.
Here are the two locations I encountered....


Forward location is great

Rear location is 'dodgy' .. to Dremel or sandwich?

 

Back looks fine to me.

 

I use the hard rubber jack pads mentioned on PistonHeads, they are an affordable and safe option

 

it's possible, i suppose, to extend any or all cutouts by trimming them; making them longer or wider at the risk of the plastic rocker panel showing a lack of support when viewed from the side, so i simply position as much of the jack/jackstand's lifting or supporting surface as possible on the space provided. thus far, it has always proved sufficient even when the car is jacked up on two stands whether on the same or opposite sides. i view any kind of an adapter as an annoyance, consequently, i avoid their use.

when i need to get under the entire front or back end i use two floor jacks to get the car up in the air; alternately raising either side until i can insert the stands. my stand's support post is about 2 1/2" long and about 1 1/4" wide.

 

To reduce or eliminate damage to the jacking points on the car, use ice hockey pucks. They are extremely firm rubber and fit well withing the allocated pad area. Cheap too, I keep a set in the trunk just in case anyone else needs to lift the car.

 

Puddlian, just my recommendation but if you're considering doing something like dremeling your panel -- which could hurt its integrity and become very costly to fix -- that money may be better spent getting a pair of Quickjacks, which work really well with Matt's jack pads. I am torn recommending Quickjacks because I feel that they're an awful company that sends leaking units to customers and then expects the customer to fix it (rather than replacing it, themselves), so the only way I recommending purchasing a pair of these is through Costco, as they will take care of the customer if something like this is received, as they did in the case with me.

Quickjacks routinely go on sale at Costco and can come down as low as $999 sometimes or maybe even more. If you like putting up all four corners, I'd recommend this avenue or a true traditional lift for your car, as resorting to modification of panels for jacking purposes injects a lot of risk.
