XYZ Racing Circuit Master Coilovers — Mercedes-Benz SLS 2009-2014

The SLS AMG carries its 6.2-litre M159 V8 well behind the front axle, but with 571bhp routed rearward through a transaxle and a kerb weight north of 1,600kg, the standard adaptive damping was tuned for grand-touring composure rather than circuit work. The Circuit Master coilover is the answer for SLS owners who want the gullwing to actually use its mid-front layout on a B-road or a track day, not just look the part in the paddock.

This is the dedicated circuit specification in the XYZ Racing range. Spring rates and damping sit above the road-biased Super Sport tier, and the kit gives you height and damping control the factory air/adaptive setup never offered.

What this coilover does for your 2009-2014 Mercedes Benz SLS

Drop the SLS to a sensible static ride height and the front splitter starts doing real work, the centre of gravity moves closer to where the engineers wanted it before ground-clearance regulations intervened, and the visual stance finally matches the proportions of the car. Stiffer linear-rate springs reduce the squat-and-dive that bleeds confidence out of the standard car when you start trail-braking towards an apex. The 36-way damping adjustment lets you run a softer rebound for road use and firm everything for a circuit session without lifting a spanner. Body control under throttle out of slower corners tightens noticeably, and the rear axle stops wallowing under the V8’s mid-range torque.

About the Circuit Master coilover

The Circuit Master uses a monotube damper body with separated compression and rebound circuits, paired with linear-rate main springs chosen for repeatable behaviour at higher loads. Construction is steel-bodied with hard-anodised aluminium lower mounts to keep corrosion at bay on a UK car that sees winter storage. Ride-height adjustment is independent of spring preload, so you set the car’s stance without changing the working spring travel. Pillowball top mounts replace the rubber-isolated factory components, which sharpens steering response and gives you camber adjustment up front. Damping is 36-click, single-knob, accessible from the top of the strut for the front and from the lower body at the rear.

Fitment for the Mercedes Benz SLS (2009-2014)

This kit is built specifically for the ME30-platform SLS AMG produced between 2009 and 2014, covering the Coupe and Roadster bodies. It replaces the factory adaptive damper and spring assemblies front and rear. Confirm your build year against the listed range before ordering.
