Caliper render for this kit:

The C4-generation S6 is a heavy executive machine. Saloon or Avant, the quattro drivetrain and well-appointed cabin push kerb weight into territory where sustained braking becomes a thermal problem. The stock front setup handled its era competently enough, but C4 owners who run their cars hard on fast roads or at track days know that fade arrives sooner than the 2.2-litre five-cylinder’s performance warrants.
The XYZ Racing front big brake kit for the Audi S6 (1994-1997) addresses that constraint directly. It fits as a matched pair of front calipers and two-piece floating discs across the front axle, with three pad compounds, so you are not asked to settle for a single compound across every use case.
What this brake kit does for your 1994-1997 Audi S6
The quattro system distributes traction well, but under hard braking the front axle carries the majority of the deceleration load regardless of drivetrain layout. The hollow-vane discs offer a larger swept area and move heat out of the friction surface faster than the solid factory rotors, shifting the heat threshold substantially at the axle that needs it most and reducing the spongy pedal and compound fade that C4 S6 owners encounter after a series of hard stops in quick succession. The two-piece floating construction lets the disc grow with temperature without warping the bell and trims rotating and unsprung mass off the front corners, and braided lines come as part of the kit to firm up the pedal.
Three pad compounds match use. Street is the quiet, low-dust default for mixed daily use. Sport gives sharper bite on a fast-road drive. Racing handles the heat when the S6 goes circuit-side. The caliper finish is worth choosing deliberately on a car where it sits prominently behind the wheel. Included painted colours are Red, Yellow, Gold, Black and Anodized Black at no extra cost.
About the front brake kit
This is XYZ Racing’s front big brake solution, fitting a larger swept area than the factory specification allows and providing the thermal headroom the C4 platform’s considerable mass demands. The calipers are hollow-bodied as standard for strength without excess weight, with an optional Hollow Racing upgrade for repeated high-load sessions that drops the dust cover, is rated to 1000C and carries a two-year warranty. The kit is built to handle both regular road use and repeated heavy sessions without the performance degradation the stock front assembly shows under pressure.
Three pad compounds are specified at order. Beyond the included painted finishes, a Custom Color in any Pantone is available, along with premium polished-forged Titanium, Polished Gold and Polished Silver and candy Teal, Blue, Red and Orange. Discs come drilled or slotted at the same price, and centre-bell upgrades, two-tone in five anodized colours or in titanium, are selectable at checkout.
Fitment for the Audi S6 (1994-1997)
This front big brake kit is listed for the C4-platform Audi S6, covering the 1994 to 1997 model years. The fitment spans both the 2.2-litre five-cylinder turbo and the 4.2-litre V8 variants, which share the relevant front suspension geometry. If your car has been previously modified, particularly around rotor diameter or caliper mounting, confirm compatibility 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.
