XYZ Racing Tarmac Rally Coilovers — Mercedes-Benz C CLASS W205 8 CYL 4WD (Cancellation Kit for Electronic Damping) 2015-2021

The eight-cylinder, four-wheel-drive W205 C-Class left Mercedes’ factory with electronically controlled adaptive dampers, wired straight into the car’s chassis control unit. That’s a fine setup for a motorway cruise; it’s the wrong setup for a car about to be pointed down a closed tarmac stage. This Tarmac Rally coilover kit for the W205 (SKU XYZ-COIL-ME07-9-C-TR) is supplied with the cancellation module needed to take that factory electronic damping package out of the circuit entirely, so the car runs on damping you set, not damping the ECU decides for you.

Where a road-and-track coilover is calibrated around comfort with the occasional trackday, this Tarmac Rally specification for the Mercedes Benz C Class has one job: surviving sealed-stage rally speeds on surfaces that hit a chassis far harder than any circuit kerb. If this W205 is heading to stage work rather than a track paddock, this is the spec built for that use.

What this coilover does for your 2015-2021 Mercedes Benz C CLASS W205 8 CYL 4WD (Cancellation Kit for Electronic Damping)

With the OEM electronic damping controller cancelled out, every damping decision on this 4WD, V8 W205 comes from the coilover itself rather than a factory algorithm tuned for road comfort. That matters most over the kind of broken, cambered tarmac a closed stage throws up: compression events that would normally have the standard adaptive dampers hunting for a setting are instead absorbed consistently, run after run. Suppressing that shock at the body keeps the four driven wheels loaded more evenly through compressions and crests, which is where this car finds tyre traction on wet or loose-surfaced stages. The result on this specific chassis is a car that settles faster after a bump and carries that stability into the next corner, rather than still working through the last one.

About the Tarmac Rally coilover

The Tarmac Rally is XYZ Racing’s damper built specifically to absorb the impact of uneven pavement rather than filter it out gently the way a road-biased kit does. It is set up to soak up the jolt of hitting a big compression or pothole-sized dip mid-stage, suppressing the shock that would otherwise travel into the body shell, and using that control to keep the tyre loaded and gripping rather than skipping across the surface. That combination is what gives the car the stability that translates into predictable handling at speed, rather than a soft ride that falls apart the moment the road gets rough. The valving and spring rates supplied with this kit come directly from XYZ Racing’s own Tarmac Rally programme, rather than a generic fast-road setting turned up a notch, which is the point of specifying this variant over a Top Sport or Super Sport kit for a Mercedes Benz C Class headed to stage events rather than the circuit.
