XYZ Racing Tarmac Rally Coilovers — Mercedes-Benz C CLASS W205 8 CYL (Cancellation Kit for Electronic Damping) 2015-2021

Fit a manual coilover to the W205 C63’s electronically damped rear axle and the first problem isn’t spring rate – it’s the warning lights Mercedes’ Ride Control system throws the moment it can’t find its own dampers. The XYZ Racing Tarmac Rally coilover for the Mercedes Benz C-Class W205 (2015-2021), 8-cylinder cars, comes with the cancellation kit built in, so the car reads clean while a fixed, stage-tuned damper does the work in its place.

Tarmac Rally isn’t a road-comfort spec, it’s built for sealed-stage work, where a car meets crests, compressions and mid-corner bumps at speeds a public road never throws at it twice. On a V8 C63 carrying real weight over the front axle, that means a damper that can shrug off a hard landing without unsettling the rear the next time a wheel unloads.

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

On the road or into a stage, the biggest change shows up in what happens when the rear axle unloads over a crest. A fixed damper tuned for rally-spec impact absorption stops the sudden jolt from a big compression being fed straight into the shock body, which is what keeps the tyre loaded and searching for grip rather than skipping across the surface. Because the cancellation kit removes Ride Control from the equation entirely, the C63’s factory adaptive damping – and the fault code it throws without a matching sensor – is no longer part of the picture. What’s left is a chassis that settles faster after a hit and holds its line through the transition, instead of needing a beat to recompose itself before you’re back on the power.

About the Tarmac Rally coilover

XYZ Racing built the Tarmac Rally line specifically for sealed-stage events, where the road surface itself does the damage a track kerb never would: potholes, ridges, and the kind of single big hit that a circuit-focused coilover isn’t set up to absorb. The valving is tuned to soak up that impact rather than pass it straight through, keeping the shock body from being thrown around and the tyre in contact with the road through the landing. That control is what keeps the car stable and the contact patch working, rather than the axle skipping over the next ridge. The settings on this kit come directly out of XYZ Racing’s own tarmac rally programme, not a generic road-and-track compromise carried over from a different discipline. For the W205’s electronically damped rear axle, that includes the cancellation kit needed to run this fixed-rate setup without the car fighting its own Ride Control system.

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

This kit is built for the W205-generation C-Class, chassis code ME07-6-C, 8-cylinder cars from 2015 to 2021, specifically the version fitted with Mercedes’ electronic damping – hence the cancellation kit included as standard with this SKU. Confirm your car carries the factory adaptive dampers before ordering, since the delete kit is matched to that setup.
