XYZ Racing Street Advanced Coilovers — Mercedes-Benz SLK R172 6 CYL 2011-2026

The R172-generation SLK’s folding vario-roof stows low in the boot rather than folding into a canvas bag, and that shifts real weight rearward the moment you put the roof down. XYZ Racing’s Street Advanced coilover is built to keep the 6-cylinder SLK settled through that shift, rather than leaving the rear end to cope with it on its own. This is a fast-road coilover first, with enough range to still make sense on an occasional track day.

Fitted to the SLK R172, chassis code ME25, across the full 2011-2026 run, the Street Advanced kit suits an owner who wants more precision from the front end under trail braking and a rear axle that stays planted once the hardtop is stowed. It is a set-and-drive kit rather than a stripped-out motorsport rig, aimed at drivers who want control over how the car behaves, not just a lower stance.

What this coilover does for your 2011-2026 Mercedes Benz SLK R172 6 CYL

With 720 individual damping settings on offer, you get a far finer resolution than a basic multi-click damper, which matters on a car that has to do a motorway commute one day and a spirited B-road drive the next. That range lets you firm up the rear to control the extra mass the retractable hardtop carries when it is folded away, without tipping the ride into harshness. The 6-cylinder SLK carries more weight over the front axle than the four-pot cars, and having damping control at that end gives you a way to sharpen turn-in and resist nose-dive braking into a roundabout. Set hard, the car turns in crisper and settles quicker over mid-corner bumps; back the damping off and the same kit works as a comfortable daily setup.

About the Street Advanced coilover

XYZ Racing built the Street Advanced line as its most popular coilover, refined over years of development and proven through competition use by teams running XYZ equipment around the world before the technology was brought down into this road-focused spec. The headline feature is the 720-way damping adjustment, giving a resolution well beyond a basic click-adjustable damper and letting one setting cover both a normal commute and an occasional track day rather than forcing a compromise between the two. It is positioned by XYZ as essential kit for a driver who wants genuine control over pace and handling, not simply a lower ride height. On the SLK specifically, that adjustment range is what lets the kit account for the roadster’s shifting weight balance between roof-up and roof-down driving.

Fitment for the Mercedes Benz SLK R172 6 CYL (2011-2026)

This kit is specced for the Mercedes Benz SLK R172, chassis code ME25, covering the 6-cylinder cars built across the 2011-2026 production run. It replaces the factory suspension on this chassis code specifically, so confirm your SLK is the ME25-coded 6-cylinder variant rather than a four-cylinder car before ordering.
