XYZ Racing Hollow Rear Brake Kit — Audi A6 QUATTRO C5 (1997-2004)

The C5-generation A6 quattro carries its mass well forward of the front axle, and under hard braking that weight bias leaves the standard rear discs doing too little of the work. The XYZ Racing Hollow Rear Brake Kit for the Audi A6 Quattro C5 (1997-2004) restores some of that balance, giving the rear axle the heat capacity and bite to share the load instead of trailing the fronts.

This is a rear-axle upgrade aimed at owners running a heavy saloon or Avant on fast road and occasional track use, where repeated stops expose how quickly the factory rears fade. Pad compound runs from Street through Sport to Racing, so the kit’s character follows how you actually drive the car.

What this brake kit does for your 1997-2004 Audi A6 Quattro C5

On a car this front-loaded, a stronger rear end changes how the A6 settles into a stop. With more rear bite the nose dives less and the chassis stays flatter as you brake into a corner, which makes the quattro easier to place on turn-in. The two-piece floating disc trims rotational mass at the rear, so the brakes shed heat faster and the pedal holds firm after several quick stops rather than going long. Step up to the Sport or Racing compound and the rear axle keeps biting once temperature builds, the point where Street pads on a heavy estate start to glaze. Caliper finish is yours to set, from the included painted colours through to premium polished and candy options, to match the wheel choice.

About the Hollow rear brake kit

The kit pairs a two-piece floating disc with an uprated rear caliper sized for the C5 platform. Taking material out of the rotor lowers its rotational mass, which helps the rear shed heat through a sequence of heavy stops rather than soaking it. The caliper is hollow-bodied as standard to keep weight down, with an optional Hollow Racing build for track sessions that removes the dust cover, is rated to 1000C and carries a two-year warranty. Three pad compounds cover the range of use this car sees: Street for everyday driving with low dust, Sport for spirited road work, and Racing for track sessions where the rear needs to survive sustained temperature. Included painted caliper colours are Red, Yellow, Gold, Black and Anodized Black at no extra cost, with a Custom Color in any Pantone for £150, premium polished-forged finishes in Titanium, Polished Gold and Polished Silver, and candy finishes in Teal, Blue, Red and Orange, so the upgrade behind the rear spokes reads as deliberate. As a rear-only kit, a matched pair of rear calipers and discs with braided lines, it is built to complement a front big brake setup or to correct the standard balance on a car that leaves its rear axle underworked.
