XYZ Racing Pro Rally Coilovers — Mercedes-Benz C CLASS W204 4 CYL (Modified Rear Integrated) (Cancellation Kit for Electronic Damping) 2007-2014

The W204 C-Class’s four-cylinder chassis was never built with loose surfaces in mind – Mercedes-Benz tuned the factory suspension, and on higher trims the electronic damping control, around smooth Autobahn cruising, not gravel crests and ice-packed hairpins. XYZ Racing’s Pro Rally coilover strips that assumption out entirely, replacing the factory geometry with a setup built for top-flight rally competition, where the car needs to shrug off compression events a road-biased strut was never designed to absorb.

This particular kit is the professional-integration version: it fits a C-Class that has already had its rear end modified to accept a rally-spec mount, rather than bolting straight to the untouched factory chassis, and it includes the cancellation kit that disables the car’s electronic damping control so the coilover’s own valving decides how the car reacts on gravel. That distinction matters the moment you’re relying on consistent damping response through a stage rather than a comfort-tuned adaptive system second-guessing the driver.

What this coilover does for your 2007-2014 Mercedes Benz C Class W204

Swap in the Pro Rally coilover and the first thing you’ll notice on loose surfaces is how much more of the car’s weight transfer you can actually use – a rally-specification spring and damper combination keeps the rear axle loaded through a compression instead of packing down and skipping, which matters on a heavy four-cylinder saloon like the W204. Because the electronic damping control is cancelled rather than left fighting the new hardware, every adjustment you make at the coilover is the adjustment the car actually runs, with no factory intervention softening or stiffening the response mid-stage. Ride height becomes a genuine set-up tool rather than a cosmetic one: raise it for stage clearance over ruts and washouts, or drop it back for tighter, faster gravel sections where you want less roll. The professional-integration rear mount also keeps geometry changes consistent under the repeated hard landings that stage work throws at a car, rather than working loose the way an amateur-fit setup can over a season of competition.

About the Pro Rally coilover

XYZ Racing builds the Pro Rally range specifically around gravel and snow-stage use, and the range splits into two distinct installation approaches. The amateur type bolts directly into the car’s original mounting points, aimed at privateers running a largely stock chassis. The professional type, which is what this C-Class fitment uses, is designed to go in after the rear end has already been structurally modified, giving a team a mounting interface built for repeated high-load stage impacts rather than one compromised by trying to preserve the factory geometry. That professional-spec mounting is paired here with the cancellation kit needed to take the W204’s electronic damping control out of the loop, so damping behaviour is set entirely by the coilover, not blended with a factory system tuned for road comfort. It’s a kit built for teams running a genuinely prepared C-Class, not a lightly modified road car.

Fitment for the Mercedes Benz C Class W204 (2007-2014)

This kit fits the Mercedes Benz C Class W204 four-cylinder, 2007 to 2014, in the modified-rear-integrated configuration with the electronic damping cancellation kit included. Confirm your car has already had the rear end modified for professional-type mounting before ordering, as this kit is not designed to fit an unmodified factory chassis.
