XYZ Racing Tarmac Rally Coilovers — Audi RS6 4B/C5 4WD 2002-2004

The RS6 4B/C5’s twin-turbo V8 sits ahead of the front axle, and on a sealed tarmac stage that nose-heavy quattro layout wants to push wide the moment the road breaks camber or drops into a compression. The XYZ Racing Tarmac Rally coilover for this Audi RS6 4B/C5 4WD (2002-2004) is built around that exact problem: a damper calibrated to control a heavy, all-wheel-drive saloon hitting broken tarmac repeatedly at speed, not a track car nibbling at kerbs.

Where a Top Sport or Super Sport kit is tuned for smoother circuit surfaces, this Tarmac Rally spec is set up for stage conditions – camber changes, patched sections, mid-corner bumps that arrive without warning. It’s the right call if you’re running the RS6 competitively on closed tarmac stages rather than club circuit days.

What this coilover does for your 2002-2004 Audi RS6 4B/C5 4WD

Fitted to the RS6 4B/C5, this kit is calibrated to absorb the impact of broken tarmac and patched stage surfaces without transmitting the hit straight into the body structure – important on a car this heavy, where an unsettled chassis costs you the traction the quattro system is meant to deliver. Damping control over big compressions keeps the tyre’s contact patch loaded rather than skipping, which matters more on a permanent four-wheel-drive car than most, because all four corners need to stay planted for the centre diff to do its job properly. On the road that translates into a car that settles faster after a jolt, stays composed through camber changes, and lets you get back on the throttle sooner coming out of a rough section instead of waiting for the body to stop moving. Ride height and corner weights are adjustable, so you can trim the nose-heavy V8’s stance to keep turn-in sharp rather than let the standard setup’s natural understeer bias creep in further.

About the Tarmac Rally coilover

XYZ’s Tarmac Rally line is built specifically for sealed-stage work, where the surface is asphalt but rarely smooth – patched sections, ridges, and off-camber bumps repeat run after run rather than turning up once per session. The damper is valved to soak up those impacts, cushioning the big hits so the shock doesn’t pass straight through to the chassis, and keeping the tyre pressed into the road surface rather than skipping across it. That control is the point of the kit: better contact patch retention means more usable traction when you’re back on the power out of a compression. Stability under repeated hard inputs is the design brief here, not outright stiffness – a car that stays predictable run after run is quicker than one that’s simply firm. The damping settings come directly from XYZ’s own Tarmac Rally programme, developed on the surfaces this spec is meant to run rather than adapted from a road or circuit base tune.
