XYZ Racing Tarmac Rally Coilovers — Mercedes-Benz GLC X254/C254 4WD 2022-2026

The GLC X254/C254’s 4WD platform puts real weight over a nose already carrying a big six-cylinder or plug-in hybrid drivetrain, and on a broken tarmac stage that mass wants to keep travelling long after the wheel has changed direction. XYZ Racing’s Tarmac Rally coilover is built specifically to fight that: a damper tuned to catch a big compression event without kicking the body sideways mid-corner.

This is not a fast-road or track-day setup dressed up in a rally name. It is spec’d for sealed-stage work, where the road surface changes character every few hundred metres and the suspension has to keep the tyre in contact with whatever is actually underneath it.

What this coilover does for your 2022-2026 Mercedes Benz GLC

Hit a mid-corner ridge or a pothole disguised by shadow at speed and the damper’s job is to absorb that impact before it reaches the chassis – XYZ Racing’s Tarmac Rally valving is built to soak up hard, sudden compression events rather than transmitting them straight into the body. That matters most on the GLC’s 4WD platform, where a harsh hit at one corner can upset the torque split and unsettle the whole car mid-stage. The shock body itself is controlled so it doesn’t kick or buck after the impact, which keeps the tyre loaded and gearbox-flat on stage rather than skipping across the surface. Better contact patch consistency translates directly into traction – power goes down instead of spinning away over a bump – and the car’s overall stability holds up corner after corner instead of degrading as the surface roughens. For a heavy AWD platform like the X254/C254, that combination of impact absorption and body control is what keeps handling predictable when the road stops being smooth.

About the Tarmac Rally coilover

XYZ Racing built the Tarmac Rally coilover around one job: surviving uneven, broken-surface stages without the car losing its composure. The valving is set to absorb big compression events – the kind of hit you get crossing a pothole or a rutted stage section at speed – while suppressing the rebound and body movement that would normally follow. That control is what keeps the tyre’s contact patch loaded through the impact, so traction doesn’t drop off the moment the surface gets rough. The result is a chassis that stays stable and predictable through a stage rather than one that has to be caught and corrected after every bump. XYZ Racing has carried its settings for this coilover over directly from its own tarmac rally programme, so the compression and rebound characteristics reflect what the team has actually run on stage rather than a generic road-going tune. It’s a damper built for a car that’s expected to be driven hard over a surface it doesn’t get to choose.
