XYZ Racing Super Sport Coilovers — Mercedes-Benz C CLASS W204/S204 4 CYL (Cancellation Kit for Electronic Damping) 2007-2014

The W204/S204 C-Class rides on Mercedes’ factory adaptive damping in this era, and that electronic control module is exactly what this Super Sport kit is built to bypass. Fit the cancellation kit alongside the coilovers and the car’s factory ride-height sensors and damping electronics stop fighting a fixed-rate aftermarket shock, so the suspension behaves the way you actually set it up rather than the way the ECU thinks it should.

For a four-cylinder W204 or S204 saloon or estate used for fast-road driving with the odd track day, that matters more than most owners expect. Left in place, an active-damping fault code will nag at you every time you start the car. This kit removes that friction alongside delivering a proper coilover setup with 36 damping positions to work with.

What this coilover does for your 2007-2014 Mercedes Benz C CLASS W204/S204 4 CYL (Cancellation Kit for Electronic Damping)

Drop the ride height and you immediately cut the C-Class’s centre of gravity, which shows up as less body roll turning into fast roundabouts and less nose-dive under braking into a give-way line. The 36-way damping adjustment lets you run the front end firmer for direction changes without turning the rear into a kidney-shaker on a B-road with poor surfacing, which matters on a chassis that spends most of its life on UK tarmac rather than a smooth circuit. Because the cancellation kit removes the electronic damping conflict, the ride quality you dial in with the adjuster stays consistent instead of the factory system quietly overriding it at speed. Ride height is independently adjustable too, so you can settle on a stance and corner weight without touching spring preload, and correct the C-Class’s tendency to sit slightly nose-low once a few track sessions have bedded the springs in.

About the Super Sport coilover

Super Sport is built around a damper design that Mercedes owners specifically use to address the harshness that comes with lowering a road car – the factory complaint about lowering springs alone is a ride that thumps over expansion joints and drain covers, and this unit is tuned to take that edge off without going soft. Ride height adjustment sits separate from the damping circuit, so you can raise or drop the car to suit UK speed bumps and long-driveway approach angles without losing your preferred compression and rebound settings. The 36-way adjuster gives a wide enough spread to go from a compliant daily setting through to a firmer track-day position, covering the two extremes a W204 owner is likely to actually use rather than a narrow band around one compromise. Mercedes describes this as suited to both weekend competition use and everyday driving, and the spec backs that up: enough range to soften for a motorway commute, and enough control at the firm end to keep the car composed when you lean on it.

Fitment for the Mercedes Benz C CLASS W204/S204 4 CYL (Cancellation Kit for Electronic Damping) (2007-2014)

This kit is specified for the W204/S204 chassis-code C-Class, four-cylinder variants, covering the 2007 to 2014 production run. The cancellation kit is included specifically because these years used Mercedes’ factory electronic damping control, and it needs pairing with the coilovers to prevent the dash throwing a suspension fault after fitment. Confirm your car is the 4-cylinder W204/S204 variant before ordering, since 6-cylinder models in the same period use a different specification.
