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

The W205 C63’s twin-turbo V8 sits low and forward, loading the front axle harder under braking than any four-cylinder or six-cylinder C-Class in the range, and the factory AMG Ride Control adaptive dampers get overwhelmed once track temperatures and lap speeds climb. XYZ Racing’s Racing Spec coilover replaces that electronic damping system entirely, with damper settings drawn from direct involvement in WTCC competition rather than lab-bench testing.

This is built for serious track and time-attack use on the W205 C63 platform, not a fast-road compromise. Because the car left the factory with electronically controlled dampers, this kit ships with the cancellation hardware needed to remove that system cleanly, so the coilover’s own damping is the only damping in play.

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

Fitting the Racing Spec kit to a 2015-2021 C63 addresses the two things that show up first once you push this car on circuit: front-end dive under trail-braking into slow corners, and squat off the power exiting them. Independent adjustment for ride height and damping lets you set the front low enough to control that V8’s mass transfer without loading the anti-roll bars into full lock, and firm enough at the rear to keep the diff and subframe settled under hard throttle. Because the electronic damping is cancelled outright rather than left to argue with the new dampers, the car responds the way you set it up, session after session, rather than the way AMG’s software decided at a given ambient temperature. Owners running the W205 C63 at track days get a car that finally changes direction with the same urgency the engine already has, instead of one still governed by a comfort-biased factory tune underneath it.

About the Racing Spec coilover

The Racing Spec line sits at the top of XYZ Racing’s coilover range, built specifically for competitive track use rather than a dual-purpose road-and-track brief. Damper tuning isn’t pulled from a spreadsheet – it comes out of XYZ Racing’s direct involvement in touring car competition, including WTCC, where damping decisions get validated at race pace rather than on a rig. For cars carrying genuine motorsport-level modifications – factory racing builds or A-class competition cars – XYZ Racing will produce a bespoke shock absorber rather than a catalogue unit, built around the specific upgrades already fitted and the circuit the car actually runs. That custom-build route is open to any buyer prepared to detail their car’s modification list and intended track to XYZ Racing’s engineers, which makes Racing Spec as much a made-to-order programme as a fixed product line.

Fitment for the Mercedes Benz C Class W205 8 CYL (Cancellation Kit for Electronic Damping) (2015-2021)

This kit is specified for W205-chassis Mercedes-Benz C-Class 8-cylinder cars built between 2015 and 2021 – the C63 and C63 S – under XYZ Racing’s ME07-6-C fitment code. Because these cars left the factory with electronically controlled adaptive damping, the kit includes the cancellation hardware required to remove that system before the Racing Spec dampers go in. Confirm your car is the V8 W205 variant rather than the four-cylinder C200 or C300 before ordering, as fitment and part numbers differ.
