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

The B8 A5 Convertible runs considerably heavier than the coupé it shares a platform with – Audi stiffened the sills, added transmission-tunnel bracing and reinforced the bulkhead to recover the torsional rigidity lost when the roof disappeared, and the folding soft-top mechanism piles further weight above the rear axle when stowed. That structural reality amplifies the B8 platform’s characteristic nose-heaviness, shifting the balance point relative to what coupé owners expect from the same chassis. Getting suspension response right here means accounting for that weight distribution, not treating the convertible as a soft-top equivalent of its fixed-roof sibling.

Audi’s factory electronic damping logs fault codes the moment its signal loops are broken, so this XYZ Racing Top Sport kit for the 2009-2016 A5 B8 Convertible ships with the cancellation interface as part of the package. Delete the OEM adaptive units, fit the interface, and the instrument cluster stays clean.

What this coilover does for your 2009-2016 Audi A5 B8 Convertible

Running 30-50% more damping than a conventional street setting, the Top Sport manages the B8 Convertible’s additional body weight more assertively than a road-biased coilover would – suppressing the secondary bounce and float that can blunt the feel of a heavier open-body chassis through fast corners. The 2kg/mm spring rate increase over street specification tightens the nose response that can otherwise feel diffuse in the B8 convertible’s nose-heavy layout, giving the front axle a more decisive initial turn-in. Tyre contact improves through sharper rebound control, which is precisely where the open-body structure’s reduced torsional stiffness would otherwise introduce inconsistency at the limit.

About the Top Sport coilover

The Top Sport sits above XYZ Racing’s road range in ambition and calibration, carrying settings developed through track-day and aggressive-driving use. Damping runs 30-50% firmer than a standard street coilover, and spring rates are set 2kg/mm harder than road specification – numbers derived from circuit work and brought directly into a road-legal kit for drivers who want that character on track days rather than in competition. The setup is calibrated to absorb uneven surfaces and large compressions without the chassis losing composure, keeping tyre traction consistent when the road surface deteriorates mid-corner. Body control in sustained hard driving is the central concern: the Top Sport is built to suppress the secondary movement that erodes confidence on repeated fast-road or circuit sessions. Replacing Audi’s factory adaptive system entirely is the prerequisite, which is why the cancellation kit is built into this variant from the outset.

Fitment for the Audi A5 B8 Convertible (2009-2016)

This kit is engineered for the Audi A5 B8 Convertible (chassis code AU25-C) across the full 2009-2016 production span. The bundled cancellation hardware addresses the electronic damping system fitted to cars specified with Audi’s adaptive suspension option – it suppresses the fault codes generated when passive dampers replace the factory adaptive units. If your A5 Convertible was not built with electronic damping, the standard Top Sport kit without cancellation hardware is the correct order.
