XYZ Racing Street Advanced Coilovers — Mercedes-Benz C CLASS W205 6 CYL 4WD (Cancellation Kit for Electronic Damping) 2015-2021

The W205 C-Class’s six-cylinder 4WD derivatives, C400, C450 AMG Sport and C43 4MATIC among them, left the factory with electronically controlled dampers that adjust valving in real time through the car’s control module. Fit a set of coilovers to one of these cars and that module still expects a signal from a solenoid that no longer exists, throwing fault codes and warning lights unless it’s dealt with properly.

XYZ Racing’s Street Advanced coilover kit for the Mercedes Benz C Class W205 6 CYL 4WD handles that at the point of installation, pairing the coilover hardware with a cancellation kit for the electronic damping system so the swap is clean rather than a dashboard full of errors. Street Advanced sits between fast-road comfort and circuit capability, built for owners who want a lower, tauter C-Class without giving up a usable daily ride.

What this coilover does for your 2015-2021 Mercedes Benz C Class W205

Swapping the factory adaptive dampers for a mechanically adjustable coilover set changes how the W205 responds under load. With 720 damping adjustment positions to work through, you can wind compression and rebound up for a weekend on track or back off for the motorway commute without the car crashing into every expansion joint. Lowering the ride height also drops the centre of gravity, which matters more on the heavier 4WD six-cylinder cars than on the four-cylinder rear-drive versions, tightening turn-in and cutting the body roll the standard air-assisted setup was tuned to mask. Because the cancellation kit removes the electronic damping control from the equation entirely, there’s no fault-code fight between the ECU and the new hardware, and no warning lights every time you start the car. The result is a C-Class that turns in sharper, sits flatter mid-corner, and still rides well enough to use on the road between track outings.

About the Street Advanced coilover

Street Advanced is XYZ Racing’s most popular kit, refined over several seasons of use and feedback drawn from race programmes the brand has supplied around the world. It’s built for cars that see a mix of normal road use and track days rather than dedicated race duty, which is exactly the brief for a six-cylinder W205 that’s as likely to do the school run as a track day. The headline spec is 720 damping adjustment positions, giving a wide enough range to move between a comfortable commuting setting and something stiff enough to control weight transfer under hard braking and cornering. The adjustability is aimed at drivers who want to feel a proper suspension change rather than just drop the ride height for looks, and it’s built so speed and control don’t have to be traded off against each other.
