Caliper render for this kit:
The RS2 B4 is one of the very few production Avants that Porsche had a hand in assembling, built in Zuffenhausen alongside the 968 and originally equipped with Porsche 968 front calipers as standard. That was a remarkable achievement for 1993, but thirty years of hard driving, modern tyre compounds, and the realities of sustained circuit heat cycles mean the original front-axle hardware now has a credible successor.
The XYZ Racing front brake kit for the Audi RS2 B4 covers exactly that need. It fits as a matched pair of front calipers and two-piece floating discs across the front axle, with three pad compounds and a full range of caliper finishes giving owners of this rare car a properly specified upgrade for whatever use the RS2 sees, from fast-road commuting to track days.
What this brake kit does for your 1993-1995 Audi RS2 B4
The B4 quattro platform carries the turbocharged 2.2-litre five-cylinder, transfer case, and Torsen differential ahead of the front axle. It is a nose-heavy layout, and the front brakes shoulder a disproportionate share of the deceleration work. The RS2’s 315bhp arrives in a characteristically abrupt mid-range surge rather than a linear build, which means braking zones matter: arriving at them with cold, under-specified pads invites fade exactly when the car’s mass and speed are at their highest.
The hollow-vane discs move heat out of the friction surface faster than the original solid rotors, the two-piece floating construction lets the disc expand without warping the bell, and the lighter assembly trims rotating and unsprung mass off the front corners. Braided lines are included to firm up the pedal. Street is the quiet, low-dust default for everyday road temperatures; Sport widens the thermal window for harder fast-road sessions; Racing holds up through sustained high-temperature cycles on circuit. The Speedline alloys leave the calipers in plain view from the kerbside, so the finish is worth taking seriously. Included painted colours are Red, Yellow, Gold, Black and Anodized Black at no extra cost.
About the front brake kit
This is a direct-fit front-axle upgrade specified for the RS2 B4’s hub geometry. The calipers are hollow-bodied as standard for strength without excess weight, with an optional Hollow Racing upgrade for circuit sessions where sustained heat build-up demands the most fade resistance, dropping the dust cover, rated to 1000C and carrying a two-year warranty. Three pad grades are available at purchase: Street for typical road operating temperatures, Sport for the higher loadings of spirited driving and occasional track use, and Racing for committed circuit work.
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, allowing the kit to suit a concours-level restoration or a circuit-focused build with equal conviction. 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. Coverage is front axle only; this is not a four-corner upgrade.
Fitment for the Audi RS2 B4 (1993-1995)
This kit fits the Audi RS2 Avant in B4 platform specification, covering the full 1993 to 1995 production run. The RS2 ran as a single-specification model with no significant drivetrain variants affecting front hub dimensions, so the kit applies across all production years without modification. If the car has seen any non-standard hub or wheel conversion, verify the front hub bolt pattern 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.
