XYZ Racing Racing Spec Coilovers — Mercedes-Benz GLK X204 2008-2015

The GLK X204 was Mercedes’ first stab at a properly square, body-on-frame-looking compact SUV, and its standard air or steel setup leaves a lot of body roll on the table once you start asking questions of the chassis. Drop a 1.8-tonne SUV onto the original springs at a brisk B-road pace and the front end takes a beat to settle before the rear catches up – that delay is exactly what a track-focused coilover is built to delete.

XYZ Racing’s Racing Spec is the firmest, most circuit-oriented kit in the range, aimed at X204 owners running track days, hillclimbs or sprint events and willing to accept a stiffer everyday ride for genuine on-limit composure.

What this coilover does for your 2008-2015 Mercedes Benz GLK X204

Body control is the headline. The Racing Spec’s stiffer spring rates and monotube damper bodies cut the roll angle on turn-in, so the GLK loads its outside front tyre cleanly rather than leaning, washing wide, then biting late. Adjustable damping lets you tune the X204’s nose-led weight transfer under braking – useful given the front-biased layout shared across the platform. Height adjustment via the lower mount preserves shock stroke when you drop the car, which matters on a tall SUV that can otherwise crash through its bump travel on kerbs. Pillowball top mounts sharpen steering response without numbing it, and the kit ditches the spongy compliance bushings that take the edge off the standard setup.

About the Racing Spec coilover

Racing Spec sits at the firm end of XYZ’s road-legal-but-circuit-focused ladder. The dampers are monotube, gas-pressurised, with 30-way bump and rebound adjustment on a single click ring per corner – enough range to soften the kit for the drive there and stiffen it for the session. Spring rates are pitched well above OE for a kit of this category, paired with shortened shock bodies so ride height can come down without sacrificing usable stroke. Construction is full T6061 aluminium where it counts, with steel where load paths demand it, and the entire damper assembly is rebuildable and revalvable rather than a sealed throwaway unit. Camber-adjustable top mounts on the front axle let you chase more negative for tyre temperature management on circuit.

Fitment for the Mercedes Benz GLK X204 (2008-2015)

Engineered specifically for the X204-chassis GLK across the 2008 to 2015 production run, covering both rear-drive and 4MATIC variants where the suspension geometry matches. Confirm your build month if your car sits at the very start or end of that window, as Mercedes did revise minor pickup hardware mid-cycle.
