XYZ Racing Tarmac Rally Coilovers — Audi S5 B8 4WD 2007-2016

The B8 S5’s longitudinal V6 sits ahead of the front axle, and quattro all-wheel drive adds weight low in the chassis – a combination that punishes soft factory dampers the moment a tarmac stage throws a compression, a crest, or a broken edge at speed. XYZ Racing’s Tarmac Rally coilover is built around that exact scenario: a damper tuned to absorb the impact of an uneven road surface without losing body control through the fast, committed corners a closed-stage run demands.

For the S5 B8 4WD, that means a chassis that stays flat when the nose wants to dive under trail braking and a rear axle that keeps its footprint through mid-corner camber changes and mid-stage jumps. It is a kit built for drivers running sealed-stage tarmac rally events, not a fast-road compromise wearing a rally name.

What this coilover does for your 2007-2016 Audi S5 B8 4WD

Fitted to a quattro-equipped S5, the damping is calibrated to control the extra unsprung mass that all-wheel drive brings to each corner, so the chassis settles quicker after a hit rather than pattering into the next braking zone. Suppressing shock body movement over compressions and crests keeps the supercharged V6’s weight transfer predictable stage to stage, which matters when a B8’s nose-heavy balance is already working against you under trail braking. The setup increases tyre traction on the broken, patched surfaces typical of a closed tarmac stage, translating into a more planted turn-in and a rear axle that follows the front rather than stepping wide over mid-corner ridges. Owners running the S5 on tarmac events will feel the difference most over the sequences other coilovers unsettle – compression, crest, and camber change back to back.

About the Tarmac Rally coilover

XYZ Racing developed the Tarmac Rally line specifically for closed-stage events run on broken, patched, and repeatedly resurfaced tarmac rather than a circuit’s smooth asphalt. The damper is calibrated to soak up the impact of an uneven road surface and to control the jolt through a big compression or a mid-stage bump without transmitting that shock straight into the chassis. Suppressing that shock body movement is the core of the tune – it is what keeps the tyre loaded and gripping instead of skipping across a ridge or a patch repair. The valving and spring rates that ship with this kit come directly from XYZ Racing’s own tarmac rally programme, carried over from stage running rather than derived from a road-car baseline. The result is a set-up built around stability first, so the driver can commit to a line through fast rally sections and trust the chassis to hold it.

Fitment for the Audi S5 B8 (2007-2016)

This kit is built for the B8-chassis Audi S5 in its 4WD quattro configuration, chassis code AU28-1, covering the 2007 to 2016 production run. Confirm your S5 is the quattro 4WD variant before ordering, since front and rear geometry differs from any related front-drive-based B8 model.
