XYZ Racing Pro Rally Coilovers — Audi S4 B5 4WD 1997-2002

The B5 S4’s longitudinal 2.7-litre biturbo V6 sits ahead of the front axle, and quattro’s mechanical grip does nothing to correct that nose-heavy bias the moment the tarmac runs out. Push this car onto loose gravel or snow on a road-spec spring rate and the nose dives under braking, the tail steps wide on the throttle, and the standard dampers give up long before the stage does.

The XYZ Racing Pro Rally coilover is built for exactly that transition – top-flight rally competition, not a fast-road setup dressed up in rally language. It replaces the entire strut and spring assembly with a dedicated rally configuration matched to the B5’s quattro architecture front and rear, so the car can carry speed over broken surfaces instead of bottoming out on the first crest.

What this coilover does for your 1997-2002 Audi S4 B5 4WD

Fitted to the B5 S4, this kit raises the usable ride height and stiffens the damping curve enough to absorb compressions on gravel without the suspension bottoming through its travel – the failure point for road coilovers pushed onto stage surfaces. The quattro’s front-heavy weight transfer under braking is controlled rather than fought, keeping the nose off the bump stops into tighter corners. Ride height is adjustable independently of spring preload, which matters on a car whose front-to-rear weight split shifts noticeably between fuel-heavy road transits and stripped-out competition trim. Each corner is set up to work with the B5’s factory quattro geometry rather than against it, so the all-wheel-drive system’s traction advantage on loose surfaces is not undone by suspension that can’t keep the tyre loaded.

About the Pro Rally coilover

XYZ Racing builds its rally gravel and snow suspension into two distinct configurations. The first is a direct-fit setup that bolts to the original chassis mounting points with no body modification – an amateur-level entry point. The Pro Rally kit supplied here is the second, professional-grade configuration: it is designed to be fitted after the car’s body has been modified for competition use, giving the suspension geometry and travel a rally build actually needs rather than what a stock strut tower allows. That distinction is the difference between a coilover that merely survives a stage and one built around a car set up specifically to compete on one. Construction follows XYZ Racing’s motorsport-line practice of separating spring and damper adjustment so ride height, preload and compression can each be set independently once the car sits on a modified rally shell.

Fitment for the Audi S4 B5 4WD (1997-2002)

This kit is specified for the Audi S4 B5 4WD, chassis code AU14-1, built between 1997 and 2002. It is matched to the B5’s quattro all-wheel-drive layout front and rear – confirm your car sits within this chassis and year range before ordering, and note the Pro Rally configuration assumes a body already modified for competition fitment.
