XYZ Racing Tarmac Rally Coilovers — Audi A5 F5 SPORTBACK 2WD/4WD φ49 2016-2026

Sealed-stage tarmac rally punishes a suspension differently to a circuit: the surface changes character every few hundred metres, from smooth new asphalt to a broken farm-lane crossing or an unmarked crest, and it does so at speed. The Audi A5 F5 Sportback’s quattro-ultra platform already sends drive rearward under load, but the long MLB evo wheelbase and the Sportback’s extra rear overhang mean the chassis needs a damper that stays composed when a compression lands mid-corner, not just in a straight line.

XYZ Racing’s Tarmac Rally coilover is built for exactly that brief – sealed-stage pace on public-road surfaces, where ride quality and body control have to coexist metre by metre. For the A5 F5 Sportback in either 2WD or 4WD form, that means a kit tuned to absorb the jolt of a hit without kicking the tail sideways, then settle again in time for the next one.

What this coilover does for your 2016-2026 Audi A5 Sportback

The Tarmac Rally kit’s job starts with the same uneven tarmac and rough hardstanding you already pick apart at low speed – sunk drain covers, patched b-roads, potholed give-way lines. The φ49 damper body gives the shim stack more surface area to work with than a standard-diameter strut, which matters when a stage throws a compression at you every few seconds rather than every few laps. That extra bore lets the damper shed the impact energy of a heavy hit – a jump, a crest, a broken edge – without the spike transmitting straight into the AU64 chassis and unsettling the quattro-ultra driveline’s torque split. The payoff is traction: because the wheel stays loaded and in contact instead of skipping, both the 2WD and 4WD versions of this platform can put power down out of a compression rather than spin through it. Ride quality on the road between stages matters too, since an A5 Sportback still has to be driven to the start line.

About the Tarmac Rally coilover

The Tarmac Rally line is XYZ Racing’s damper tune built specifically for sealed-stage events run on public roads rather than closed circuits, where the surface is rarely flat and rarely predictable. The valving is set up to soak up the impact of uneven pavement and absorb the jolt of a big hit – a pothole, a broken edge, a crest landing – without sending that shock straight into the bodyshell. Suppressing that shock is what keeps the tyre loaded and gripping rather than skipping across the surface, which is where the traction gain comes from. XYZ Racing says the damping curve is drawn directly from its own Tarmac Rally programme, so the settings reflect what its cars actually run on stage rather than a generic road-going compromise, and the result is a car that holds its line and its stability through repeated hits.

Fitment for the Audi A5 (2016-2026)

This kit is built for the Audi A5 F5 Sportback, chassis code AU64, covering the 2016 to 2026 model years across both 2WD and 4WD quattro-ultra drivetrains. The φ49 damper body is sized to the F5 platform’s factory strut mounts, so confirm your build year and drivetrain against the AU64 code before ordering.
