XYZ Racing Circuit Master Coilovers — Aston Martin DB9 2004-2016

The DB9’s party trick is its drivetrain layout: a V12 mounted well behind the front axle, a torque tube running through the cabin, and the six-speed transaxle slung at the rear. That arrangement delivers weight distribution figures most sports cars never achieve from the factory – yet on a circuit, the stock adaptive damping setup still tells the story of a car built to cruise the Côte d’Azur rather than set times at Donington. It floats, it rolls, and it softens inputs that the stiff VH aluminium structure underneath could actually translate into something sharper.

For sustained circuit work in a DB9, the XYZ Racing Circuit Master coilover for the AS02 platform (2004-2016) addresses that mismatch directly. This is not a road-and-track compromise – it is a dedicated circuit specification: three independent adjustment knobs delivering 9,720 discrete damping combinations, with small-oil-passage internals built to maintain consistent response when the car is loaded through extended cornering sequences.

What this coilover does for your 2004-2016 Aston Martin DB9

The DB9’s near-50/50 weight balance means the chassis is genuinely receptive to damper changes – you are not fighting an inherent handling deficit before the suspension work even begins. Replacing the comfort-biased stock setup with the Circuit Master reduces the body roll that causes the car to wash wide in sequence corners, and the three-knob adjustment architecture lets you tune compression, rebound, and ride height independently. That separation matters: you can stiffen the front for better turn-in without sacrificing the rear composure the car’s balance depends on. The VH aluminium monocoque responds to the increased damper resolution with sharper, more readable feedback through the steering.

About the Circuit Master coilover

The Circuit Master sits at the top of the XYZ Racing coilover programme, developed through XYZ’s own racing operation and tested by their teams across international circuits. The three-knob configuration separates low-speed compression, rebound, and preload adjustment into distinct controls, giving 9,720 possible combinations across the full range – resolution that covers everything from club-day Silverstone configurations to faster circuits where high-speed body control is as critical as corner-entry stability. The small-oil-passage internal design is built for track use: the damper oil routes through a restricted passage under large suspension inputs, which can produce a minor mechanical note over sharp kerbs or aggressive road imperfections. This is a characteristic of the design and entirely normal at circuit speeds where surface inputs are managed. The Circuit Master is a circuit-specific specification; it is used in Racing Spec, Drift Spec, and Tarmac Rally configurations across different classes of motorsport.

Fitment for the Aston Martin DB9 (2004-2016)

This kit is built to XYZ chassis code AS02, covering the Aston Martin DB9 from the 2004 model year through to the close of production in 2016. The fitment spans both the original DB9 and the revised DB9 GT introduced for 2015, which retained the same VH platform geometry front and rear throughout the car’s production run.
