XYZ Racing Pro Rally Coilovers — Mercedes-Benz C CLASS W204 8 CYL (Modified Rear Integrated) (Cancellation Kit for Electronic Damping) 2007-2014

The W204 C63 AMG’s naturally aspirated V8 sits nose-heavy over a live rear axle that was never asked to cope with loose surfaces, and that is exactly the brief for the XYZ Racing Pro Rally coilover kit fitted to this Mercedes Benz C Class. Standard C63 dampers are built around Mercedes’ electronic damping control, tuned for tarmac grip and smooth motorway compliance, not for a car being thrown sideways across gravel and snow.

This Pro Rally kit is built for top-flight rally competition, not fast-road use, and this particular fitment is the modified rear-integrated version with a cancellation kit for the electronic damping system. It replaces the factory electronically adjustable dampers outright rather than working alongside them, which is what the C63’s control unit needs once the suspension is taken off-road.

What this coilover does for your 2007-2014 Mercedes Benz C Class W204 8 CYL (Modified Rr Integrated) (Cancellation Kit for Electronic Damping)

With the OEM electronic damping cancelled out, the Pro Rally kit gives you a suspension platform tuned specifically to how a rear-driven M156 V8 behaves once traction drops away underneath it. Damping and ride height are set mechanically, so the car responds the same way over a rutted gravel stage as it does through standing water or hard-packed snow, with no electronic control unit trying to guess what surface it is on. The rear-integrated mounting addresses the axle loading a live rear end sees under repeated compression on rough stages, where standard mounting points are not built for that cycle count. Ground clearance and travel are set up for the terrain rather than a smooth B-road, which matters when the C-Class’s kerb weight is coming down hard through a rut or crest. For a car that already wants to rotate under power, having dampers you can trust at both ends is what keeps that V8’s throttle-out oversteer manageable rather than terminal.

About the Pro Rally coilover

XYZ Racing splits its rally-specific line into two distinct builds. One is designed to bolt straight onto an unmodified chassis, closer to an amateur or clubman spec. The other, fitted here, is the professional configuration: it is built around a car whose body has already been modified to accept it, which is standard practice once you are running at a competitive rally level rather than a weekend stage-rally hobby event. That modified-body fitment is what allows the rear-integrated mounting and the electronic-damping cancellation kit to work together as one system, rather than being retrofitted around parts the factory never intended to remove. The construction reflects what gravel and snow stages actually do to a car: repeated hard compression, debris strikes, and a far wider spread of grip levels than any tarmac setup will see. It is built to be stripped and reset between events, not left untouched for years the way a road coilover might be. This is a professional-grade rally product for the C Class, not a fast-road kit wearing a rally badge.

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

This kit is specified for the Mercedes Benz C-Class W204, 8-cylinder variants built between 2007 and 2014, the C63 AMG generation, chassis code ME44-C. It is built specifically for cars fitted with the modified rear-integrated mounting and requires the cancellation kit for the factory electronic damping system, so it is not a like-for-like swap onto an unmodified W204 – the rear end needs preparing for this configuration first. Confirm your car matches this exact ME44-C specification before ordering.
