XYZ Racing Street Advanced Coilovers — Mercedes-Benz C CLASS W204/S204 6 CYL 2007-2014

The W204 and S204 C-Class carry Mercedes’ factory comfort tune even on the V6 cars – soft spring rates and compliant bushings that let the nose dive under trail braking and let the body roll settle mid-corner before the chassis actually commits. On the S204 estate, that extra mass over the rear axle exaggerates the same trait under load. The Street Advanced coilover is XYZ Racing’s road-and-track kit for owners who want that softness gone without losing the ability to drive the car every day.

It replaces the factory strut and spring assembly front and rear with a coilover set offering 720 damping adjustment positions, so the same car can be set up plush for the motorway commute and firmed up for a track day without swapping parts. For a nose-heavy 6-cylinder W204, that range matters more than a single fixed rate ever could.

What this coilover does for your 2007-2014 Mercedes Benz C Class W204/S204 6 CYL

Lowering the spring perch and tightening compression damping cuts the nose dive that the factory C-Class setup allows under hard braking into a corner, so the front tyres load up sooner and turn-in becomes more direct. Stiffer rebound control keeps the S204’s rear end settled over mid-corner bumps instead of letting the extra estate mass pogo the axle. Ride height is adjustable independently of spring preload, so you can correct the factory rake, clear larger brake kits, or simply bring the stance in line without touching the damping curve you’ve already dialled to suit your roads. Because the 720-position adjuster covers both ends of the range, the same kit copes with a motorway trip on Friday and a track day on Saturday – reset the clicks, not the parts.

About the Street Advanced coilover

Street Advanced sits at the centre of XYZ Racing’s coilover line-up and is built around the same monotube damper architecture the brand has refined across its racing programme, carried over into a kit aimed squarely at road use with the occasional circuit outing. The headline figure is 720 damping adjustment positions, giving a far finer resolution than the handful of clicks typical of a basic strut, which is what lets one setup cover both a daily commute and a lapped session without feeling like a compromise in either direction. Construction favours durability over minimalism, with height-adjustable spring perches that let ride height and preload be set independently of the damping curve. It’s positioned as the kit for drivers who want genuine control over how the car rides and handles, rather than a fixed factory compromise, without stepping up to a full track-only setup that would be unpleasant to live with day to day.

Fitment for the Mercedes Benz C Class W204/S204 6 CYL (2007-2014)

This kit is specced for the Mercedes Benz C Class W204 saloon and S204 estate 6-cylinder models built between 2007 and 2014, chassis code ME06. Confirm your car falls within this production window and carries a 6-cylinder engine before ordering, since 4-cylinder and AMG variants on the same platform use different corner weights and are catalogued separately.
