Fits Audi A6 QUATTRO C5 (1997-2004)

Brake pad compound

Street: quiet, low-dust, strong cold bite for road driving. Sport: higher temperature range and more bite for fast road and occasional track. Racing: maximum fade resistance for sustained track use (noisier and dustier cold). Match the pad to how hard you actually brake.

Disc size

Caliper grade

Hollow is the standard caliper: a lighter hollow-body forged caliper with a dust cover and a 5-year warranty. Hollow Racing drops the dust cover for sustained high-temperature use (rated to 1000°C, 2-year warranty) — the track-grade choice.

Caliper colour

Painted colours are included. Polished-forged finishes are mirror-polished forged calipers (Titanium, Gold, Silver); candy colours are a deep, mirror-reflection paint. Both are premium upgrades — fuller detail further down the page.

Disc style

Drilled discs (cross-drilled holes) vent gas and water and look aggressive; slotted discs (surface grooves) wipe the pad face clean and resist fade under sustained hard use. Same price — choose on looks or how you drive.

Centre bell

The centre bell is the CNC-machined aluminium hat that joins the disc to the hub. Standard anodized is included; a two-tone bell adds an anodized accent ring in your choice of colour; titanium is the lightest, forged option.

Carbon-ceramic rotor

Carbon-ceramic rotors are a special-order track upgrade: far lighter than steel, fade-resistant at extreme temperatures and extremely long-lived. The price follows the disc size you choose above. The standard two-piece steel rotor is included.

XYZ Racing Hollow Front Brake Kit — Audi A6 QUATTRO C5 (1997-2004) — 330 mm
330 mm

The C5 A6 Quattro arrived in 1997 as a fast-road executive hauler. The 2.7 biturbo variant produces 250 bhp from the factory and north of 300 bhp with a remap on standard turbos, but the platform still weighs over 1,600 kg. That mass sits nose-heavy on the front axle, and the Torsen centre differential that makes the quattro system so effective under acceleration does nothing to redistribute weight under braking. The XYZ Racing front brake kit closes the gap between what the factory specification was built for, a business saloon covering motorway miles, and what a biturbo A6 with rewritten maps actually demands.

This is a front-axle pair: left and right front calipers with matched two-piece floating discs. The lighter discs reduce rotating mass at the front axle, a detail that matters on a heavy, front-biased platform where cutting rotating mass improves not just stopping distances but the front end’s ability to respond to steering inputs at the limit. On a C5 Avant carrying a full load, or a saloon pressed hard on an empty A-road, the OE front spec shows its ceiling quickly under repeated high-speed braking.

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

Weight distribution on the C5 A6 Quattro puts the majority of braking load at the front axle; the quattro system’s Torsen centre bias toward the rear for traction does not reverse under deceleration. Larger swept area and greater caliper clamping force at the front shorten stopping distances and deliver a firmer, more consistent pedal as temperatures climb. The hollow-vane disc design sheds heat faster than a solid casting between stops, and braided lines hold the pedal firm where rubber hoses would swell. Three pad compounds scale the setup to the car’s demands: Street is the quiet, low-dust default for a 2.4 V6 on daily fast-road duty, Sport widens the heat range for harder use, and Racing is the track compound for a chipped 2.7T being asked to scrub speed from motorway-plus velocities repeatedly. Calipers are hollow-bodied as standard, with a Hollow Racing upgrade for serious track use, rated to 1000C, no dust cover, two-year warranty.

About the Front Brake Kit

The two-piece floating disc reduces the rotating mass of the disc relative to a conventional ventilated design of comparable swept area, and the hollow-vane internal geometry moves air through the rotor body for faster heat rejection. On a large, front-biased platform like the C5 quattro, keeping unsprung rotational weight in check has a measurable effect on both steering response and the disc’s thermal management through repeated cycles. Three pad compounds are offered, Street, Sport and Racing, each targeting a distinct friction coefficient and operating temperature range. Discs come in drilled or slotted face at the same price, with optional two-tone centre bells in five anodized colours or titanium at checkout. Included caliper colours are Red, Yellow, Gold, Black and Anodized Black at no extra cost, with a Custom Color in any Pantone for £150 and premium polished-forged (Titanium, Polished Gold, Polished Silver) and candy finishes (Teal, Blue, Red, Orange) also available, so you can specify a finish that works with the wheel and bodywork combination.

Fitment for the Audi A6 QUATTRO C5 (1997-2004)

This kit is built for the Audi A6 Quattro C5, covering the full 1997-2004 production span across both saloon and Avant body styles in Quattro specification. The installation is front-axle specific. Buyers with higher-output factory variants or non-standard factory brake configurations should verify existing caliper mounting dimensions before ordering.

Choosing your spec

Every kit is built to order around the choices you make above. Here is what each option actually changes, so you can spec yours with confidence.

Brake pads — Street, Sport or Racing

Every kit ships with a full set of high-performance pads; the compound is your call.

Street is the right default for fast-road driving — a strong, progressive cold bite with low noise, low dust and long disc life. Sport raises the working temperature and adds bite and fade resistance for hard road use and the occasional track day, while still behaving on a cold morning. Racing is a track compound built for sustained abuse: huge fade resistance and bite once heat is in it, at the cost of more noise and dust when cold. Match the pad to how hard you actually use the brakes — there is no benefit to a race pad that never gets up to temperature.

Caliper grade — Hollow vs Hollow Racing

Hollow is the standard caliper on every kit: a hollow-body forged caliper, lighter than a solid one, fitted with a dust cover and backed by a 5-year oil-leak warranty. For most fast-road and spirited track use it is all the caliper you need.

Hollow Racing is the track-grade upgrade. It runs the same hollow body but without a dust cover (so there is nothing to melt at sustained high temperature), uses a twin-metal piston that isolates heat travelling from the disc to the oil seal, and is rated to 1000°C. Available 286–380mm (front). Warranty is 2 years on oil leaks and 10 years on appearance. Built for professional racing and repeated track days.

Caliper colour & finish

Painted colours (Red, Yellow, Gold, Black, Anodized Black) are included at no cost. Want an exact match to your car? Custom Color (+£150) paints the calipers to any Pantone code you supply (15–20 day lead time).

Polished Forged finishes are the flagship: a forged caliper given a mirror-polished surface treatment that shifts colour with the viewing angle. Beyond the looks, the polished surface dissipates heat better, resists rust and stands up to the weather. Choose Titanium (neochrome, +£350), Polished Gold (+£300) or Polished Silver (+£250). They look their best paired with a titanium centre bell. Care: clean only with a dilute neutral cleaner or water.

Candy colours (+£200) use a deep candy-paint and polishing process for a mirror-reflection, boutique finish — pick Teal, Blue, Red or Orange (shown below right).

Centre bells

The centre bell is the CNC-machined aluminium hat that joins the disc to the hub. The standard anodized centre bell is included. The Two-tone bell (+£200) adds an anodized accent ring — choose Red, Yellow, Orange, Purple or Silver right here at checkout. The Titanium centre bell (+£500) is a forged titanium bell (bolts not included) that finishes off the polished-forged look.
