XYZ Racing Pro Rally Coilovers — Audi S5 B8 4WD 2007-2016

Quattro’s permanent all-wheel drive gives the B8-generation S5 a traction advantage that most front-drive or rear-drive rally builds have to fight for, but the factory ride height and damping were tuned for road use, not a gravel stage littered with compressions, crests and off-camber landings. XYZ Racing’s Pro Rally coilover replaces that road-biased set-up with a unit built around the AU28-1 chassis specifically for loose-surface competition.

This is the top end of the range, aimed at top-flight rally competition rather than a fast-road or track-day remap of the standard suspension. Every mounting point, spring perch and damper stroke is worked out against the S5’s actual chassis geometry, not adapted from a generic Audi platform.

What this coilover does for your 2007-2016 Audi S5 B8 4WD

On a stage car, the biggest threat to pace isn’t outright grip, it’s the suspension running out of travel or the damper losing composure over repeated hits. This coilover extends usable travel and firms up the damping curve so the AU28-1 chassis stays controlled over jump landings and compressions instead of bottoming out or pattering across ruts. Ride height is adjustable independently of spring preload, which matters on a car this heavy, letting you set stage-appropriate ground clearance without throwing off the corner weights quattro’s drivetrain layout depends on. Paired with the S5’s all-wheel-drive traction, the result is a chassis that puts power down through washboard gravel and snow instead of skating over it, with the front and rear axles working together rather than the rear simply following the front.

About the Pro Rally coilover

Rally suspension built for gravel and snow is a different discipline to tarmac coilovers, and XYZ Racing’s Pro Rally line reflects how competition teams actually approach the build. There are two routes into this spec: a version that bolts straight into the factory AU28-1 mounting points, giving teams a quicker and simpler way onto a stage without touching the car’s structure, and a second configuration engineered for cars that have already had their body and subframe reworked for a full works-level build. Both share the same core hardware philosophy – travel, damping and adjustability set up for repeated high-speed impacts rather than smooth road surfaces – but the second is built to work with a modified chassis rather than an unmodified factory shell. Which route suits a given car comes down to how far the rest of the build has already gone.

Fitment for the Audi S5 B8 4WD (2007-2016)

Built specifically for the AU28-1 chassis code covering the quattro Audi S5 B8 across the 2007 to 2016 production run. Confirm your car matches this chassis code and year span before ordering, as B8 and B8.5 running changes affected mounting points across the model’s life.
