XYZ Racing Super Sport Coilovers — Mercedes-Benz GLK X204 2008-2015

The X204 GLK is one of the few compact SUVs of its era built on a proper rear-drive saloon platform – the C-Class W204 underneath, with the ride height and softer damping that comes with the SUV brief. That hardware bones-up well, but the factory tune leaves the GLK rolling on its outside front in committed corners and floating over crests at motorway speed. The XYZ Racing Super Sport coilover is the part that resets that balance.

This is the fast-road set for a 2008-2015 X204 owner who wants the car to sit lower, turn flatter, and stop pitching under braking, without giving up the everyday comfort that made them pick a GLK in the first place. It is the right pick for a road-biased Mercedes Benz GLK X204 build that occasionally sees a B-road or a continental drive rather than a circuit weekend.

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

Drop the X204 onto a properly matched spring rate and the body-control improvement is the first thing you feel – the nose stops diving on the brakes and the rear stops squatting when the V6 loads up. Through a roundabout, the outside front holds its line instead of leaning onto the sidewall, so the steering rack actually loads up and gives you something to read. Ride height is adjustable independently of preload, so you can take the wheel-arch gap out without coil-binding the spring or shortening bump travel. Damping is adjustable on the same body, which means the daily setting can stay civilised while a stiffer click handles a loaded boot or a long, fast sweeper. Brake feel improves as a byproduct: less pitch means more consistent pad bite into the disc.

About the Super Sport coilover

Super Sport is XYZ Racing’s road-and-occasional-track set, sitting above the entry tier and below the Circuit Master and Racing Spec circuit kits. Construction is monotube with an enlarged piston, which trades the cheaper twin-tube layout for better heat dissipation and more linear damping force as the oil warms up. Spring rates on this fitment are matched to the X204’s kerb weight and the GLK’s higher centre of mass – softer than the equivalent C-Class set, because dropping a saloon rate into an SUV gives you a harsh ride and no extra grip. Height is set on a threaded lower mount rather than spring preload, so you keep full stroke at any ride height inside the adjustment window. Damping is single-adjustable, blending bump and rebound on one knob – the right call for road use, where most owners will set it once and leave it.

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

This kit is specific to the X204 chassis, covering the full 2008-2015 production run of the GLK in both the pre-facelift and post-facelift forms. It is matched to the standard MacPherson front / multi-link rear layout used across the X204 range. Confirm your exact variant (GLK 220 CDI, 250, 350, etc.) at the configurator below as some four-cylinder and V6 variants take different spring rates.
