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

The W205 C-Class’s factory electronic damping control is built to be the only thing managing body movement – fit a mechanical coilover without dealing with that control loop first and the car will fight the new dampers rather than work with them. This kit pairs the coilover with a cancellation solution for the 6-cylinder W205’s electronic damping system, so the car reads the new suspension correctly instead of throwing faults or reverting to a compromised default map.

Tarmac Rally is built around sealed-stage work: sustained compression events over broken tarmac, camber changes and mid-corner ruts rather than a single big hit. On a nose-heavy 6-cylinder W205, that matters – the V6 up front loads the outside front tyre hard under trail braking, and a stage car needs the front axle to stay planted through repeated compressions rather than just the first one.

What this coilover does for your 2015-2021 Mercedes Benz C Class W205

Once the electronic damping cancellation is in place, the Tarmac Rally kit takes over ride control outright rather than sharing it with a factory sensor loop. The damper is built to absorb the shock of uneven tarmac and swallow big hits without kicking that jolt back into the body, which keeps the C-Class’s rear multi-link axle settled instead of skipping across broken surfaces. That composure under load is what translates into more usable tyre contact – the car finds traction on the way into and out of a corner instead of losing it the moment the surface gets rough. For a 6-cylinder W205 carrying more weight over the front axle than the four-cylinder cars, that stability shows up most under braking and initial turn-in, where the standard setup would otherwise let the nose push.

About the Tarmac Rally coilover

XYZ Racing’s Tarmac Rally coilover is built specifically to cope with the punishment of sealed-stage rallying – broken surfaces, sustained high-speed compressions and the kind of jolts a fast-road or circuit coilover isn’t set up to absorb. The valving is set to soak up impact from rough pavement and big hits without transmitting that shock back through the chassis, protecting both the car’s structure and the driver’s ability to keep the throttle open. That same control is what keeps the tyre loaded and gripping rather than skipping, which is where the stability comes from. XYZ Racing draws these settings directly from its own tarmac rally programme, so the damping behaviour reflects what the type has actually needed to survive a stage rather than a generic road-going compromise.

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

Built for the W205-generation Mercedes Benz C-Class, 6-cylinder variant, covering the 2015 to 2021 model years under chassis code ME07-5-C. This listing includes the cancellation kit required for cars fitted with the factory electronic damping system – fit it alongside the coilover rather than the standard kit if your C-Class left the factory with adaptive dampers.
