XYZ Racing Super Sport Coilovers — Mercedes-Benz SLK R172 6 CYL 2011-2026

The R172 SLK’s six-cylinder cars carry noticeably more weight over the front axle than the four-pot versions, and on the factory dampers that shows up as a softer, less controlled front end the moment you load it into a fast corner. The XYZ Racing Super Sport coilover corrects that balance and gives the platform the front-end response the chassis has always had the potential for.

Aimed at fast-road driving with weekend track days folded in, Super Sport sits between comfort-biased setups and full race kit. It keeps the SLK usable on a motorway run to the circuit and composed once you’re actually on it, without turning every pothole into a jolt through the seat.

What this coilover does for your 2011-2026 Mercedes Benz SLK R172

Ride height is fully adjustable, so you can drop the SLK’s stance to tighten the roll centre and cut aero lift at speed, or set it higher for a daily-driver ride that clears speed bumps without drama. The 36-way damping adjustment is the headline feature here: on a car this nose-heavy, having that much range means you can firm up compression on the front struts specifically to control dive under braking into a hairpin, then back the rear off a step to keep the tail settled through direction changes. Because the range spans road conditions as well as pace, one set of dampers covers a wet B-road commute and a dry trackday without swapping parts. The result on the R172 is sharper turn-in, less body roll through fast direction changes, and a front axle that finally works with the six-cylinder engine’s weight rather than against it.

About the Super Sport coilover

Super Sport is built to take the harshness out of UK road surfaces while still giving you the adjustment range a track day demands. The 36-way damping control lets you move from a firm, controlled setting for circuit work down through progressively softer stages for broken tarmac and long motorway stints, all from the same damper. Ride height adjustment is independent of that damping range, so lowering the car for a track session doesn’t force a compromise on how the damper reacts to bumps. XYZ Racing designed this tier specifically to bridge weekend racing and everyday use, which is exactly the brief for an SLK owner who wants one car doing both jobs. It’s a step up in adjustability from a comfort-only setup without pushing into the stiffness of a dedicated race coilover.
