XYZ Racing Pro Rally Coilovers — Mercedes-Benz C CLASS W205 6 CYL (Cancellation Kit for Electronic Damping) 2015-2021

Top-flight rally competition on gravel and snow puts a different set of loads through a six-cylinder Mercedes Benz W205 than any tarmac brief does: ruts, camber changes and compression hits arrive continuously, and the diff and driveline need even loading through all of it. XYZ Racing’s Pro Rally coilover is built around that brief rather than adapted from a road-going kit. Because Mercedes ties the W205’s adaptive damping into the car’s control modules, this fitment is supplied as a cancellation kit – it removes the electronic damping signal path so the coilover’s own valving takes over cleanly.

That matters more on the six-cylinder C Class than most: these cars carry extra weight over the front axle and put more torque down through loose surfaces than the four-cylinder variants. Fixed mechanical damping means the suspension behaves the same way on the fortieth stage as the first, with no control unit intervening on a ride height or damper curve it was never told about.

What this coilover does for your 2015-2021 Mercedes Benz C Class W205 6 CYL (Cancellation Kit for Electronic Damping)

On loose surfaces, ride height and corner-weight control decide whether the car stays planted through a rut or gets thrown off line by it – the Pro Rally coilover’s independent height adjustment lets you set the car for stage-specific ground clearance without touching spring preload. Damping circuits set up for rally-speed inputs keep the wheel following the ground through repeated hits rather than skipping, which keeps the six-cylinder engine’s torque going through the diff instead of into wheelspin. Because the electronic damping cancellation kit removes the factory adaptive system entirely, there is no control-module intervention fighting the coilover’s own valving mid-stage. The result on a 2015-2021 C Class W205 is a suspension that responds to what the surface is actually doing under the car, not what a sensor thinks it should be doing.

About the Pro Rally coilover

XYZ Racing built the Pro Rally line specifically for gravel and snow competition, not as a stiffened version of a road coilover. The range splits into two distinct build types to match how a car is prepared: one variant bolts straight onto an unmodified chassis for crews running a standard-bodied car, while the second is built around a modified body shell for cars that have already been seam-welded, caged and structurally reinforced for full competition use. That split exists because a stock chassis and a fabricated rally shell carry loads through different mounting points, and a coilover designed for one will fight the other. Construction favours travel and adjustment range over ride refinement – this is damping tuned for repeated large-amplitude hits rather than small-bump isolation on smooth tarmac. For the W205’s electronic-damping cars, the cancellation kit is part of the same package: it exists so the coilover’s mechanical valving is the only damping input the car sees, with nothing from the factory control system layered on top.

Fitment for the Mercedes Benz C Class W205 (2015-2021)

This kit is specified for the Mercedes Benz C Class W205, six-cylinder variants, built between 2015 and 2021, and is supplied as the cancellation-kit version for cars fitted with Mercedes’ electronic adaptive damping from the factory. If your car does not carry the factory adaptive damping system, the standard Pro Rally kit (without cancellation hardware) is the correct fitment instead.
