XYZ Racing Tarmac Rally Coilovers — Audi A5 B8 CONVERTIBLE (Cancellation Kit for Electronic Damping) 2009-2016

The B8 A5 Convertible carries considerably more mass than its Coupé sibling – Audi’s structural reinforcement for the open body adds to the kerb weight in ways that matter on a tarmac stage, where crests and compressions test the damper’s ability to keep the front axle planted. These coilovers from XYZ Racing replace the factory electronic damping system entirely, via the included cancellation kit, substituting the OEM sensor-and-module loop for a mechanically configured setup drawn directly from sealed-stage rally competition.

Tarmac stages across the UK and mainland Europe vary enormously in surface quality. Sections that appear smooth on spectator footage routinely include abrupt crests, drainage repair patches, and mid-corner compressions that can unsettle the front end on a heavier platform like the Convertible. The Tarmac Rally spec is built around those conditions.

What this coilover does for your 2009-2016 Audi A5 B8 CONVERTIBLE (Cancellation Kit for Electronic Damping)

Removing the factory adaptive damping architecture and replacing it with the Tarmac Rally setup changes the fundamental character of how the B8 Convertible responds to road inputs. The OEM electronics react; these dampers absorb – specifically the kind of large, irregular bumps that tarmac stage surfaces deliver. Body movement through sharp compressions is suppressed, which keeps the tyre’s contact patch in meaningful contact with the surface rather than bouncing away from it. On a nose-heavy front-engine platform, maintaining that front-axle traction on a staged road is where control is won or lost. Vehicle stability across varied surface inputs is what the calibration is aimed at.

About the Tarmac Rally coilover

Every setting in the Tarmac Rally series originates from competition use on sealed stages, not circuit work repurposed for road-surface rally use. The damping profile is configured to absorb the impact of uneven tarmac – the kind of road surface a competitive stage is actually run on – with particular attention to the shock load imposed by large crests and abrupt surface transitions. Shock body movement is suppressed actively, rather than simply softened, which maintains traction as the car returns to the road following a significant input. The calibration delivers vehicle stability and consistent handling across the kind of surface variation a tarmac stage presents, where the inputs are less predictable than a circuit but the speeds are comparable. Settings are derived from XYZ Racing’s own competitive experience, not from laboratory simulation.

Fitment for the Audi A5 B8 CONVERTIBLE (Cancellation Kit for Electronic Damping) (2009-2016)

This kit covers the A5 B8 Convertible across the full 2009-2016 production run (chassis code AU25-C). The included cancellation kit addresses the electrical architecture specific to B8 Convertibles fitted with the factory electronic damping option, allowing a clean installation without stored fault codes. Buyers should confirm their car carries the adaptive damper system – this is the correct SKU where that hardware is present.
