XYZ Racing Street Advanced Coilovers — Mercedes-Benz SLK R172 4 CYL 2011-2026

The R172 SLK’s folding hard-top adds weight high in the body, and on the standard springs that shows up as float over motorway undulations and a slightly lazy turn-in when you finally get it onto a good road. The Street Advanced coilover is XYZ Racing’s answer for owners who want the roadster tightened up for spirited driving without turning it into a car you dread on a rough B-road.

This isn’t the track-focused end of the range. It’s built for the SLK owner who wants sharper body control on a Sunday blast and still wants to drive to work Monday without every expansion joint coming through the seat.

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

Fitted to the R172, the kit lowers the centre of gravity and firms up the spring and damper rates enough to check the body roll that the factory setup allows through fast direction changes – noticeable the first time you load the front end into a roundabout. The damping adjustment lets you back the compression off for a broken motorway surface, then wind it up again before a series of B-road bends, so the same car can do both jobs without a fresh set of springs. Because the range is built around 720 damping settings, the increments between one click and the next are small enough that you can nudge the ride toward comfort or control without ever landing in a compromise you don’t like. For a car that splits its time between commuting and occasional hard driving, that range of adjustment matters more than outright stiffness.

About the Street Advanced coilover

Street Advanced is the model XYZ Racing built as its core product, developed and refined over several years of the brand’s motorsport programme and validated in competition before making its way into road-going form. The line between the two isn’t accidental – lessons from those race outings, including events run worldwide under the XYZ name, shaped how the damper responds under load rather than just how it looks on a spec sheet. The defining number is the 720-way damping adjustment, giving a genuinely fine-grained window between a road-biased setting and something firm enough for a track day, all through a single external adjuster rather than a compromise fixed at the factory. It’s aimed squarely at drivers who split their car’s use between daily roads and the occasional session on track, rather than one or the other exclusively. For an SLK owner, that flexibility is the whole point: one set of coilovers, adjustable enough to suit whichever kind of day you’re having behind the wheel.

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

This kit is specified for the Mercedes Benz SLK R172, chassis code ME24, covering the 4-cylinder model years from 2011 through 2026. Confirm your car sits within this chassis and engine designation before ordering, as coilover geometry is matched to the R172’s specific mounting points and won’t cross over to the earlier R171.
