XYZ Racing Racing Spec Coilovers — Mercedes-Benz C CLASS W204 4 CYL (Modified Rear Integrated) 2007-2014

The W204 C-Class is rear-wheel drive with a nose-heavy four-cylinder up front and a multi-link rear axle that has to do the work of putting power down under braking and corner exit. On a car built as a comfortable executive saloon rather than a track tool, the standard dampers run out of control long before the chassis does – body roll builds mid-corner, the rear axle squats under throttle, and the front dives hard enough under braking to upset your turn-in point. The Racing Spec coilover exists to put that damping budget back on the car’s side.

This is XYZ Racing’s motorsport-homologated damper line, and it’s the spec built specifically for circuit and time-attack days rather than a fast-road compromise. On the ME05-1 fitment, that means the "Modified Rr Integrated" rear mounting is engineered into the kit rather than bodged on – the rear shock integrates with the W204’s factory multi-link geometry instead of fighting it.

What this coilover does for your 2007-2014 Mercedes Benz C Class W204 4 CYL (modified Rr Integrated)

With the Racing Spec kit fitted, the C-Class stops rolling into corners and starts rotating on command – the reduced ride height and stiffened, adjustable damping cut the weight transfer that makes a stock W204 wallow under load. Braking stability improves because the front end no longer dives and unsettles the front tyres’ contact patch right when you need maximum grip. Corner-exit traction improves too: with the rear properly controlled instead of squatting, the M271 four-pot’s torque gets to the tarmac instead of into body movement. Because the damping is adjustable, you can run it firm for a track day and back it off a notch for the road drive home, rather than living with one fixed compromise.

About the Racing Spec coilover

XYZ Racing built the Racing Spec line around damping data pulled directly from circuit racing programmes, including WTCC-level competition, rather than from a fast-road baseline scaled up. That means the valving is calibrated for sustained lateral and longitudinal load, not just a stiffer spring wound onto a road damper. For cars carrying heavier factory-level or A-class racing modifications – bigger brakes, aero, weight changes – XYZ Racing also offers a bespoke shock absorber build: tell them what’s been changed on the car and which circuit it runs, and the valving gets tuned around that specific setup rather than a generic track preset. For most W204 track builds the standard Racing Spec calibration covers it; the custom route is there for the cars pushing further.

Fitment for the Mercedes Benz C CLASS W204 4 CYL (modified Rr Integrated) (2007-2014)

This kit is built for the W204-chassis C-Class four-cylinder, 2007 to 2014, using the modified rear-integrated mounting under chassis code ME05-1. Confirm your car matches the four-cylinder W204 generation and the rear-integrated mounting configuration before ordering, as XYZ Racing’s W204 range is split by engine layout and rear mount type.
