XYZ Racing Gravel Rally Coilovers — Mercedes-Benz C CLASS W204 6 CYL (Modified Rear Integrated) 2007-2014

The W204 C-Class carries its inline-six and V6 engines over a chassis tuned for motorway comfort, not axle articulation over a rutted forest stage. Rear Integrated modification aside, the multi-link rear end was never asked to soak up square-edge compressions at speed on a loose surface, which is exactly the brief for the XYZ Racing Gravel Rally coilover fitted to chassis code ME06-1.

Built for gravel-stage rally use rather than tarmac lap times, this kit trades short-travel circuit stiffness for long-stroke compliance, keeping the rear-drive W204 tracking straight and predictable when the surface changes from packed gravel to washboard ruts mid-stage.

What this coilover does for your 2007-2014 Mercedes Benz C Class W204 6 CYL (Modified Rr Integrated)

Swap the factory dampers for this kit and the first thing you notice on a loose surface is how much further the rear axle can move before it runs out of travel. The long stroke and long spring combination lets the W204’s rear end follow the ground through compressions and off-camber ruts instead of skipping across them, keeping the inside rear tyre loaded and traction available out of hairpins. The inverted tube damper body copes with the sandstone, snow or silt content of a typical gravel stage without the damping fading away run after run. At the front, the same long-travel logic keeps the axle tracking through braking zones into loose corners, where the six-cylinder W204’s nose-heavy weight bias wants to push wide the moment the suspension stops keeping a tyre in contact with the ground.

About the Gravel Rally coilover

XYZ Racing developed the Gravel Rally coilover specifically for rally and rallycross, where the road surface underneath the car changes more aggressively than in any other branch of motorsport. The damper uses an inverted tube layout, so the assembly keeps working cleanly through the sandstone, snow and silt that would quickly foul a standard road-biased unit. Stroke length and spring length are both extended well beyond a circuit-focused setup, giving the axle room to absorb chassis vibration and the repeated hard hits of a bumpy, high-speed gravel road instead of transmitting them straight into the shell. That extra travel also has to cope with the sharp G-force spikes generated when a rally car turns in on loose surfaces, where lateral grip is lower and load transfer more sudden than on tarmac. XYZ Racing’s own rally team set and tested the spring rates on this kit, so what ships is a competition-proven rate rather than a desk-calculated compromise.

Fitment for the Mercedes Benz C Class W204 6 CYL (Modified Rr Integrated) (2007-2014)

This kit is built for the W204-generation Mercedes Benz C-Class fitted with a six-cylinder engine, chassis code ME06-1, across the 2007 to 2014 production run. The Rr Integrated modification accounts for the W204’s multi-link rear end, integrating the coilover into the factory rear geometry rather than requiring a separate spring-and-damper conversion. Confirm your car matches the six-cylinder W204 specification before ordering, as four-cylinder variants sit on a different fitment kit.
