XYZ Racing Super Sport Coilovers — Audi A8L 4WD (OE FOR AIR STRUT) 2010-2017

The D4 A8L is a long-wheelbase luxury saloon that left the factory riding on adaptive air struts, and that’s the problem this kit solves. Once the air system starts leaking – and on a 2010-2017 car, it will – the OE replacement bill makes a coilover swap look like the obvious answer. The XYZ Racing Super Sport coilover for the Audi A8L 4WD (OE FOR AIR STRUT) replaces the failure-prone air setup with a height-adjustable, damping-adjustable steel coilover that’s actually serviceable.

This is the fast-road and weekend-track spec in the XYZ range, so it’s tuned for an A8L owner who wants the car to feel composed on a B-road rather than wallow into corners on tired bags. You keep the ride-height adjustment the air system gave you, gain 36-way damping control, and lose the dread of a compressor failure on a cold morning.

What this coilover does for your 2010-2017 Audi A8L 4WD

On a 4.0-tonne-curb-weight luxury barge with quattro running gear, body control is the variable that decides whether the car feels expensive or floaty. The Super Sport’s 36-way damping lets you firm up the rebound enough to stop the nose pitching under braking – a real issue on the long-wheelbase A8L when the air struts are past their best. Ride height comes down to a stance the car was never offered with from the factory, without resorting to lowering links or a hacked air management module. The steel construction also means no more dash warnings about suspension faults every time the temperature drops. For weekend track work, you get a damper that actually controls the mass of the W12 or 4.2 TDI nose through quick direction changes instead of leaning on it.

About the Super Sport coilover

The Super Sport sits in XYZ Racing’s range as the fast-road plus occasional-track damper, and it’s built around a 36-way adjustable damping circuit that the driver tunes from a single knob per corner. Construction is a serviceable monotube coilover with separate spring perch and damper body, so ride height adjusts independently of preload – the right way to do it on a heavy car where you don’t want to compress the spring just to drop the nose. The damping range is wide enough to cover broken UK tarmac at one end and a Bedford or Cadwell session at the other, which is the brief XYZ is hitting with this series. Spring rates are matched to the chassis weight rather than a generic suspension book, important on a car this heavy. Suitable for both weekend race and daily use, per the engineering brief, with the rebuildable design meaning the kit isn’t a disposable item.

Fitment for the Audi A8L 4WD (OE FOR AIR STRUT) (2010-2017)

This kit is built specifically for the D4-generation A8L 4WD chassis (AU49) running the factory air-strut configuration, covering 2010 to 2017 production. The "OE FOR AIR STRUT" designation matters – it confirms this is the direct-replacement variant for cars originally equipped with air suspension at all four corners, not the steel-spring conversion path some owners attempt.
