XYZ Racing Gravel Rally Coilovers — Audi S3 SEDAN 8V φ55 (Modified Rear Integrated) 2013-2020

The S3 Sedan 8V’s quattro all-wheel-drive system puts power down through almost anything, but a factory damper was never built to survive a full gravel stage at speed. XYZ Racing’s Gravel Rally coilover swaps that road-biased strut for a design built specifically for the abuse of a special stage – compressions, jumps and the kind of high-frequency chatter a circuit-spec damper would never see.

This is the setup for S3 Sedan drivers running loose surfaces rather than closed tarmac – forest stages, rallycross venues, anywhere the road disappears under sand, snow or silt. It is not a fast-road compromise dressed up as a rally part; it is built around a different set of loads entirely.

What this coilover does for your 2013-2020 Audi S3 Sedan

Long stroke and long spring travel give the S3 Sedan’s suspension somewhere to go when a rut or compression arrives faster than tarmac driving ever throws at it, soaking up chassis vibration before it reaches the quattro drivetrain and steering. The inverted tube layout keeps the damper working through the aggressive, high-speed bouncing a gravel stage produces, instead of packing down and transmitting every hit straight into the chassis. Under hard cornering on loose surfaces the S3’s weight transfer generates real G-force through the rear subframe and front end alike, and the spring rate here is set to hold the car’s attitude rather than let it wallow. The result is a chassis that stays composed when the surface underneath it keeps changing from one corner to the next.

About the Gravel Rally coilover

XYZ Racing built the Gravel Rally line specifically for rally and rallycross use, where road conditions are more aggressive than anything a circuit or fast-road setup has to deal with – the shock absorber becomes the single most stressed component on the car. An inverted tube damper design was chosen to keep performance consistent across the wildly different surfaces a rally stage throws up, from sandstone and silt to snow. Stroke length and spring length are both extended well beyond a standard coilover, giving the damper the travel to absorb chassis vibration and shrug off aggressive impacts from high-speed, bouncy sections without bottoming out. That extra travel also has to cope with the extreme G-forces generated when a rally car turns in on a loose surface, where grip levels shift constantly. Every spring rate offered in this range has been validated by an XYZ Racing rally team rather than set on a bench, so the numbers reflect what actually survives a stage rather than a lab test.
