DB9 Suspension Upgrade – Stage 2

DB9 Suspension Upgrade – Stage 2 *Please note that this a “works only” service that can only performed at our premises at Lakeside – Essex* We have developed an extremely effective DB9 Suspension Upgrade – Stage 2 geometry package, utilizing the H&R Springs set to give a 25mm lower ride height, improved ride with added response and a sharper feel during both normal road and aggressive driving. It looks fantastic too! 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! 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. For those interested in Chassis Performance Upgrades and Fast Road Setups, our Optimum G certified expert has prepared an interesting white paper here. For those interested in the science behind this subject, we have written an interesting white paper which you can read here Just some of the Chassis Dynamics services we offer; Chassis modelling – We can build mathematical models of existing chassis to better understand the nuances of a given design Complete chassis and suspension system design Redesigning of front or rear suspension sub-systems to suit a pre-existing chassis Spring rate advice and selections Anti roll bar rate advice and design optimisations Suspension arm/link design, optimisation and modelling Suspension geometry settings both static and kinematic Limited slip differential advice and optimisation Tyre advice, size and shape, construction and compounds Roll cage and other chassis reinforcements, design and advice Chassis Dynamics equipment and facilities Whole Chassis design modelling and evaluation software Tyre simulation and modelling software Corner weight measuring equipment with flat patch Vehicle dynamic performance measuring equipment Snap-on 3D Arago optical chassis alignment jig
