XYZ Racing Tarmac Rally Coilovers — Mercedes-Benz S CLASS W221 (NON ABC hydraulic or 4WD) 2006-2013

The W221 S-Class wears its two tonnes well on Airmatic, but the moment a spring bag tears or a strut starts leaking the whole car slumps and the bill from Mercedes makes owners look elsewhere. The Tarmac Rally coilover replaces that ageing air system outright with a conventional damper-and-spring setup engineered for serious driving, not just ride-height correction.

This is the rally-derived end of the XYZ Racing range, built around stiff spring rates and high-rebound damping. On a long-wheelbase saloon it reads as a deliberate choice: an owner who wants the W221 to corner flat and recover quickly over broken surfaces, with the bonus of finally being able to set the ride height to where it should sit.

What this coilover does for your 2006-2013 Mercedes Benz S CLASS W221 (NON ABC hydraulic or 4WD)

A W221 on tired air will porpoise over motorway expansion joints and roll lazily into a B-road bend. Tarmac Rally rates kill that movement at the source. Body control becomes predictable, the front end stops diving on hard braking, and the rear settles instead of squatting under throttle out of slow corners. Adjustable damping lets you walk back from a full rally tune to something tolerable for daily use, while the threaded perch gives you precise corner-balanced ride height instead of the Airmatic system’s binary self-levelling. For owners running staggered wider wheels, the height adjustment also clears the arch-to-tyre geometry properly.

About the Tarmac Rally coilover

XYZ Racing’s Tarmac Rally spec is positioned for sealed-surface stage work and fast tarmac driving. Construction is monotube with a separate threaded lower body for ride-height adjustment independent of preload, which matters on a heavy car where you do not want to wind spring tension into a static loaded position. Damping is externally adjustable across a multi-position range, letting you bias compression and rebound to suit surface and load. Spring rates are firmer than the road-biased Super Sport or Circuit Master kits in the XYZ range, reflecting the tarmac-rally remit. The kits are valved and sprung specifically for the W221 chassis weight rather than carried over from a generic platform.

Fitment for the Mercedes Benz S CLASS W221 (Years 2006-2013)

This kit fits the W221 S-Class chassis (chassis code ME35) built 2006 to 2013, specifically the variants that left the factory without ABC hydraulic suspension and without 4MATIC four-wheel drive. If your car is an S 600, S 65 AMG, or any 4MATIC-equipped W221, this is not the correct kit. Standard rear-wheel-drive Airmatic and steel-sprung cars are the target fitment.
