Aston Martin DB9 Fast Road Setup

*Please note that this a “works only” service that can only performed at our premises at Lakeside – Essex*

As far as we know we’re the first Chassis Dynamics specialist to turn our attention to the Aston Martin marque. We started with the V8 Vantage, then continued with the V12 Vantage, Vanquish and of course the DB9, and are pleased to have received 100% positive feedback from the users.

As we see it there are two fundamental issues when the vehicles leave the factory. Firstly the recommended geometry settings are far from ideal, and secondly the cars seldom have the recommended settings applied. The second issue is easy enough to rectify by visiting an alignment specialist (caveat – avoid the usual “quick-fit” type places or anywhere that relies on the red and green light systems because they aren’t accurate enough). We don’t know what the original geometry calibration design brief was, or whether insufficient development was allowed, but we do know that the DB9 handling is far from ideal! We find that the chassis is quite numb, offering under-steer, over-sensitive traction control, and lack of transient linearity, which are all quite disappointing in a Sports Tourer!

There’s a couple of white papers we prepared that you may find helpful here and here,  but in short our Chassis Dynamics Technicians are able to optimise the geometry to even out the front/rear grip balance and to fully exploit the tyre contact patch, which gives more rear grip to reduce the traction control interference, and to linearise the chassis responses to command/control inputs. In a nutshell this provides the driver with a much greater level of confidence to use the car to it’s full potential at pace.
