XYZ Racing Tarmac Rally Coilovers — Mercedes-Benz GLC X253/C253 6CYL 4WD 2016-2022

A tall crossover body, 4MATIC torque split, and the extra ride height built into the GLC’s platform all work against you the moment a tarmac rally stage tightens up. Load transfer arrives later than it would in a saloon, then arrives all at once, and the standard suspension is tuned for comfort, not for holding a line through a stage that swings from clean asphalt to cracked, cambered farm tarmac in the space of two corners. The XYZ Racing Tarmac Rally coilover kit for the Mercedes Benz GLC X253/C253 6CYL 4WD (2016-2022) is built around that specific problem.

This is a sealed-stage tarmac rally set-up, not a fast-road or circuit spec. The damping is calibrated to keep the tyre in contact with broken and uneven surfaces rather than to minimise roll on a smooth track, which is the compromise a GLC needs to make if it’s going to be competitive off the beaten line.

What this coilover does for your 2016-2022 Mercedes Benz GLC

Fitted to a 2016-2022 GLC, this kit is built to absorb the impact of rough, uneven tarmac rather than transmit it straight into the chassis – the difference between the front axle skipping over a broken surface and the tyre staying planted through it. Big hits and mid-corner jolts get suppressed at the damper rather than passed into the bodyshell, which matters on a tall 4MATIC platform where body movement is already amplified by ride height. The practical result is more consistent tyre traction over surfaces that change grip level from one metre to the next, and a GLC that settles rather than pitches when a stage transitions from smooth tarmac to a patched, cambered section. On a car this size and weight, with all-wheel-drive torque constantly redistributing under the standard AIRMATIC-style setup, that stability is what lets you carry speed into a corner with confidence instead of backing off for the unknown.

About the Tarmac Rally coilover

The Tarmac Rally coilover is XYZ Racing’s damper for sealed-stage tarmac events specifically, built to soak up the shock of uneven road surfaces and heavy compressions without upsetting the chassis. Internal damping control is tuned to catch big hits cleanly, reducing the jolt that would otherwise travel through the body and unsettle the platform mid-stage. That control is what keeps the tyre loaded and gripping rather than skipping across broken tarmac, which is where lap time is actually won or lost on a rally stage. The valving in this kit reflects settings drawn from XYZ Racing’s own Tarmac Rally programme, rather than being adapted from a circuit or fast-road base spec.
