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

The Audi S3 Sedan 8V’s quattro drivetrain piles weight over the front axle, and on a gravel stage that mass transfer arrives faster than tarmac ever demands – compression through a rutted crest, then an instant load reversal into the next braking zone. XYZ Racing’s Gravel Rally coilover is built around exactly that: long-stroke, long-spring construction that keeps the wheel following broken ground instead of skipping across it.

This fitment covers the 2013-2020 Audi S3 Sedan 8V built with the Modified Rr Integrated rear geometry and supplied with the Cancellation Kit for Electronic Damping, so the factory adaptive damper electronics are cancelled out and the car runs as a fully passive, stage-spec unit. It’s built for gravel and rallycross competition, not a fast-road commute – sandstone, snow, silt, whatever the route throws at it.

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

Fit this to a stage-prepared S3 8V and the first difference you’ll feel is how much ground the front axle can cover before it runs out of movement. Quattro already loads the front struts hard under trail-braking into a hairpin; the inverted-tube design and extended stroke give that axle somewhere to go when a compression catches it off guard, rather than sending the hit straight into the bulkhead. The longer spring works with that stroke to soak up sustained chassis vibration over washboard sections, keeping the car settled instead of skittering sideways. Because the electronic damping cancellation kit takes the factory adaptive system out of the loop entirely, there’s no adaptive-damper fault light arguing with the passive setup mid-stage, and whatever spring rate you choose holds for the whole run, not just the first few kilometres.

About the Gravel Rally coilover

XYZ Racing’s Gravel Rally coilover is built specifically for rally and rallycross use, where the road surface changes from one stage to the next and is consistently the harshest condition any XYZ damper has to survive. The design centres on an inverted damper tube, chosen so the unit can be tuned across sand, snow or silt without the setup falling apart between recce and start line. Both stroke length and spring length run well beyond what a road or track coilover offers, giving the damper room to absorb chassis vibration and take repeated hits from high-speed, bouncy ground, along with the extreme G-forces a gravel stage generates mid-corner. Every spring rate in this range has been set and confirmed by an active rally racing team rather than calculated on a bench, so what you’re fitting reflects what has actually held up on stage.

Fitment for the Audi S3 SEDAN 8V φ55 (Modified Rr Integrated) (Cancellation Kit for Electronic Damping) (2013-2020)

This kit is specified for the Audi S3 Sedan, chassis code AU54-C, across the full 2013-2020 8V production run, in φ55 rear strut diameter with the Modified Rr Integrated rear geometry. It includes the Cancellation Kit for Electronic Damping, so cars originally built with adaptive dampers run this as a fully passive rally setup without tripping electronic ride-control faults.
