DB9 Shock replacement

Anyone changed their shocks/struts to aftermarket products? If so, which brand?

Not sure if this will be any help but...

I managed to get a 2005 DB9 about 6 months ago and frankly I was quite disappointed with the ride quality. I actually thought that the previous owner must have fitted track suspension because the ride seemed so firm to me. Having taken an Aston engineer outside for a short spin he confirmed that this was indeed how all DB9's drove. Arghh! So I was faced with the prospect of finding softer suspension somehow. I'm medically retired and therefore completely unable to contemplate the AM option for 5000 (uk) nor the aftermarket suspension specialists (Bilstein, etc) - yes, I know the definition of an optimist being someone who can just afford an Aston and then hopes he can afford to run it! It was a lifelong dream which I had to at least try...

My sort of solution was to find a specialist who was willing to modify the stock dampers. Amazingly I succeeded and it only cost me 500 including shipping!!! They opened up the dampers and changed the valveing to let the oil flow more easily. They set everything using a suspension dynamometer to my requirement of 25% softer damping. THAT was my big mistake - I wanted a significantly more compliant ride but I now find the car is somewhat inclined to float across the road with less directional stability compared to the stock setup. It's not bad, just a bit less confidence-inspiring than it was before. Also I have found myself grounding the front spoiler far more easily and I have to be a lot more cautious with driveways and bumpy or rough roads. On reflection I should have more subtle and limited my change to 10 or 15% softer but (being disabled and a cheapskate!) I didn't want to end up doing more than one modification.

This MAY be one way to go for you but it isn't easy finding the right people to do the job in the first place and then you have to be ready to try different solutions. These may include damping AND springs. In fact, the specialists I used told me that they could also supply adjustable dampers for about twice the price - not bad, all things considered. Unfortunately they told me this AFTER the dampers had been modified, returned and refitted to the car! My fault, I guess, for having gone to them with a very specific request so they took it to mean I must of course know EXACTLY what I really needed! So an adjustable damper is a very good idea If you don't know exactly what change you need to make.

Another option would be to find out more about using a different make, or even size, tyre although I would recommend driving another member's car with those tyres on to make a truly worthwhile judgement.

I doubt you will get absolutely the right answer from my varied suggestions but, with patience and perseverance, you may be able to find your perfect solution without selling the car!

Cheers, Mark

Hi Mark

Thank you for taking the time to explain your experience. Seems I'm not losing my mind and not the only one who thought the standard suspension was just too hard.

I found a mechanic in Florida (car there for the winter) who suggested exactly what you did, change the valving on the shock and get one that is adjustable. So that's the next move.

Thank you again for the confirmation that we are on the right track.

Cheers and season greetings.

Might I suggest that you may also want to pay some attention to the tires.

The Bridgestones are horribly hard I have found the Michelin PSS are much, much better.

You are correct. Car had Bridgestones. The suspension was so hard, got sidewall bubbles in first week I had car. Now running PSS's. Put 295 rear and 245 front. On stock rims. Fit fine and look great. But did little to improve ride quality. Now I'm told Pirelli was way to go. Maybe when these get used up.

With thanks

I am a little late seeing your post, but I have swapped out the springs on my DB9. I have the prototype lowering springs from Stuart at VelocityAP. I know you mentioned shocks, but springs are also worth a look. Especially since Stu just listed a sale on them. Its worth noting that I have the sportspack suspension and noticed an improvement in comfort.

Also, I had a 07 DB9 Volante and the suspension in general was much softer, so those springs might actually be a bit stiffer, while still absorbing bumps just as well as the sportspack springs. Stuart can probably give you a much better idea, and might even pair them with some shocks with his sale going on if you twist his arm.

Good luck with your search.
