XYZ Racing Super Sport Coilovers — Mercedes-Benz SLK R172 8 CYL 2011-2026

The R172 SLK55 AMG carries a 5.5-litre V8 up front, and that mass shows up first under braking and off the apex, where the factory sports suspension lets the nose dive and the tail follow late. XYZ Racing’s Super Sport coilover is built for exactly that trade-off: fast-road driving with enough capability in reserve to hold the chassis flat when you lean on the SLK’s power at a trackday.

This is the mid-tier setup in the XYZ Racing range for the SLK – a step up from ride-comfort-first kits, built to keep a folding-hardtop roadster’s extra weight in check on a circuit without turning the drive home into an ordeal.

What this coilover does for your 2011-2026 Mercedes Benz SLK R172 8 CYL

With 36-way damping adjustment, you can wind compression and rebound up for a trackday morning and back off again for the motorway home, which matters on a car whose standard damping was tuned around comfort rather than outright body control. Independent ride height adjustment lets you drop the SLK’s centre of gravity and correct the nose-heavy stance that comes from carrying a V8 and a folding roof mechanism over the front axle, sharpening turn-in without overloading the front tyres. Firming the front end also cuts the dive under braking that the standard set-up allows, so pedal feel stays consistent through repeated hard stops. On the road, the same adjustability means you can back the damping off for a comfortable cruise without touching ride height, so the car stays usable outside of trackday weekends.

About the Super Sport coilover

The Super Sport line sits in the XYZ Racing catalogue as the damper built to cover both ends of ownership – hard-driven weekends and everyday commuting – rather than being biased fully to one. Each corner offers 36 stages of damping adjustment, a wide enough spread to move from a soft, comfort-biased setting that smooths out UK B-road surfaces to a firm setting that resists roll and dive on circuit. Ride height is independently adjustable at each corner, so stance and corner balance can be set without disturbing the damping curve already set. The construction is built to take the edge off rough tarmac that stiffer track-only dampers transmit straight into the cabin, which is what keeps this a genuine daily-driver option rather than a trailer queen. It’s the same brief many R172 owners are actually working to: one set of dampers doing a Monday commute and a Saturday track session equally well.

Fitment for the Mercedes Benz SLK R172 (2011-2026)

This kit is built specifically around the R172-generation SLK’s ME26 platform, covering the full 2011-2026 production run of the 8-cylinder AMG cars. Mounting points, spring perches and damper lengths are matched to the R172’s suspension geometry, so no adapter brackets or spacers are needed at installation.
