XYZ Racing Street Advanced Coilovers — Mercedes-Benz C CLASS W204/S204 8 CYL (Cancellation Kit for Electronic Damping) 2007-2014

The W204/S204 C-Class arrived with an optional Agility Control electronic damping system on its 8-cylinder variants, and that factory hardware has to be properly cancelled out before any aftermarket coilover can do its job without fault codes or conflicting damper signals. This Street Advanced kit is built with that cancellation requirement solved from the outset, so the C63’s standard-fitment sensors and control unit stop fighting the new dampers the moment they’re installed.

Once the electronics are sorted, what’s left is a genuinely capable street and track-day platform. The W204 C-Class carries its weight low but nose-forward under the big V8, and a coilover set with real adjustment range lets you trim that balance rather than live with the factory compromise between comfort and body control.

What this coilover does for your 2007-2014 Mercedes Benz C Class

Fitted to a 2007-2014 C-Class W204/S204 8-cylinder, this kit brings 720-way damping adjustment to a chassis that otherwise only offers Comfort and Sport modes from the factory switch. That range of adjustment means you can soften the low-speed compression for motorway and B-road driving, then wind in more control for a track day, without swapping parts. Height adjustment lets you correct the nose-down stance the V8 cars tend to settle into and get the front-to-rear ride height back in balance, which sharpens turn-in on a car that can otherwise feel like it’s leading with its chin. Firmer damping also checks the body roll and dive under braking that come with the extra mass of the 8-cylinder engine over the front axle, so the chassis stays flatter and more predictable when you’re pushing on into a corner.

About the Street Advanced coilover

Street Advanced is XYZ’s core product line, refined over years of development by the in-house engineering team and proven through racing use before it reaches road cars. It’s built around 720 damping settings, giving a far finer resolution of adjustment than a basic two- or three-stage damper, so the ride can be tuned in small, deliberate steps rather than broad jumps between too soft and too firm. The line is designed to cover both everyday road use and track day work from the same set of dampers, rather than forcing a choice between a comfortable commute and a car that can hold its composure on circuit. It’s aimed at drivers who want genuine control over how their car sits and handles, not just a lowered stance, and the adjustment range reflects that – enough scope to dial out the specific character traits of the car you’re fitting it to.

Fitment for the Mercedes Benz C Class (2007-2014)

This kit is built for the Mercedes Benz C-Class W204/S204, 8-cylinder variants, across the 2007 to 2014 production run, and includes the cancellation kit required to disable the factory electronic damping system on these cars. Confirm your C-Class is the W204 saloon or S204 estate chassis with the V8 engine before ordering, since the cancellation hardware is specific to cars originally fitted with Agility Control.
