XYZ Racing Super Sport Coilovers — Mercedes-Benz SL R230 2002-2011

The R230 SL is a heavy GT – a 1.8-tonne grand tourer with a folding metal roof, Active Body Control on most trims, and a chassis tuned at the factory for refined cruising rather than apex hunting. That brief shows up the moment you push one: body movement that builds slowly, a front axle that runs out of support under sustained load, and a rear that wants more discipline when you ask the car to change direction quickly.

The XYZ Racing Super Sport coilover is the fast-road answer for owners who want the R230 to feel like a proper sports car again without losing its long-legged composure. It is the Super Sport spec – the model in XYZ’s range that targets daily-driven, weekend-spirited use rather than circuit lap times.

What this coilover does for your 2002-2011 Mercedes Benz SL R230

Installed on an R230, the Super Sport tightens up the body movement that defines a factory SL the moment cornering loads stack up. Damping is 30-way adjustable on rebound, so you can soften the kit off for a long motorway run to Goodwood and stiffen it for a B-road blast on the way home. Ride height is independently adjustable on spring perch and lower mount, which matters on a car this heavy – you can drop the stance for the look without dragging the kit’s usable travel into the bump stops. The front-end response under trail-braking sharpens noticeably, and the rear stops pattering over mid-corner bumps that the original dampers shrug past.

About the Super Sport coilover

The Super Sport sits in the fast-road tier of XYZ Racing’s coilover hierarchy. Construction is monotube with a hardened piston rod and a pillow-ball upper mount on applications where the OE top mount is a wear item rather than a structural one. Spring rates are matched to the kerb weight and weight distribution of the R230, not lifted from a lighter generic application. The damping circuit is 30-position adjustable, biased toward rebound control so you can tune body composure without harshening the primary ride. Internals are rebuildable and re-valvable, which on a heavy 5.0-litre and 5.5-litre platform like the R230 is the difference between a kit you replace at 40,000 miles and one you service.

Fitment for the Mercedes Benz SL R230 (2002-2011)

This kit is built for the R230 chassis, covering the 2002 to 2011 production run – SL 350, SL 500, SL 550, and the AMG variants share the platform, though ABC-equipped cars need the spec confirmed before ordering because Active Body Control changes the rear suspension architecture. Front and rear are matched as a set for the R230’s weight bias.
