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

The W204 C-Class 8-cylinder cars carry their weight low and forward of the front axle, and under hard trail braking that mass wants to keep travelling in a straight line while the multi-link rear tries to rotate the car underneath it. On cars specified with factory electronically controlled damping, that balance is locked to a system you can’t easily retune. This kit removes that variable: it’s built around a cancellation kit for the electronic damping and a modified, fully integrated rear mount, so the car runs on a conventional, mechanically adjustable coilover rather than a system fighting the ECU for control of ride height and compression.

Street Advanced sits between a fast-road setup and a dedicated track kit. It’s aimed at owners who want a C-Class that’s composed on a B-road on a Tuesday and confident on a track day at the weekend, without the compromises either use case usually forces on the other.

What this coilover does for your 2007-2014 Mercedes Benz C CLASS W204 8 CYL (Modified Rr Integrated) (Cancellation Kit for Electronic Damping)

Fitted to the 2007-2014 W204, the kit gives you 720 individual damping combinations to work through, which is enough range to run a genuinely soft, compliant setting for the daily commute and wind it up hard for a trackday without swapping parts. Lowering the centre of gravity through height-adjustable perches reduces the nose-dive that a heavy V8 up front generates under braking, and it sharpens turn-in by cutting body roll through the multi-link rear. Because the electronic damping is cancelled rather than left partially active, the ride response you dial in with the collar stays consistent lap to lap and mile to mile, instead of being overridden by the factory control unit. Owners running this on the 8-cylinder W204 typically notice the biggest gain in mid-corner stability, where the standard air or electronic setup tends to feel soft and reactive rather than settled.

About the Street Advanced coilover

XYZ Racing developed the Street Advanced platform over several years of iteration, and the version in this kit has been run and refined through motorsport events by teams using XYZ hardware. It’s built as an all-rounder rather than a specialist: the 720-way damping adjustment is the headline figure, giving a far finer resolution of tuning than a basic single- or few-stage adjustable strut. Construction follows XYZ’s usual monotube approach, with a threaded body for ride-height adjustment independent of spring preload, so you can set the car’s stance without changing how stiff it feels. For the W204 8-cylinder application specifically, the kit bundles the rear-integrated mounting modification and the electronic-damping cancellation hardware needed to make a factory-adaptive car run a fixed mechanical coilover cleanly, rather than leaving two damping systems working against each other.

Fitment for the Mercedes Benz C CLASS W204 8 CYL (Modified Rr Integrated) (Cancellation Kit for Electronic Damping) (2007-2014)

This kit is built specifically for the W204-chassis Mercedes-Benz C-Class, 8-cylinder variants, across the 2007 to 2014 production span. It includes the modified rear-integrated mounting hardware and the cancellation kit required to disable the factory electronic damping control on these cars, so no additional adaptor parts are needed to run a mechanical coilover on a car originally specified with electronic dampers.
