XYZ Racing Hollow Front Brake Kit — Audi 80 B4 AVANT (1991-1996)

The B4 Avant was Audi’s final expression of the traditional 80 platform: heavier than the saloon by a meaningful margin, loaded further still in touring use, and running on brake hardware calibrated for a car that spent most of its working life as a sensible family estate. This XYZ Racing front brake kit replaces that ageing original specification with larger hollow-vane discs, an upgraded four-piston caliper in your choice of finish, and three pad compounds.

At thirty-plus years old, the B4’s ATE front calipers have earned their retirement. The OEM specification was adequate for the car as Ingolstadt intended it. It was not specced for the demands modern enthusiasts place on these classics: fast A-roads, hillclimb entries, historic circuit days, and touring events where the Avant’s estate body and, on quattro variants, additional nose-end drivetrain mass put more thermal load through the front axle than the factory ever anticipated.

What this brake kit does for your 1991-1996 Audi 80 B4 AVANT

Larger discs with hollow-vane cooling draw heat away from the friction surface during sustained braking, reducing the fade that builds through repeated hard stops, a step the original B4 items could not manage. The hollow-body caliper cuts unsprung mass at the corner, and two-piece floating discs let the rotor expand with heat without warping against the bell, so the pedal stays firm deeper into a session.

Three pad compounds map to use. Street is the quiet, low-dust default for the rebuilt daily driver back in regular road use. Sport handles fast-road work where consistent bite and progressive modulation matter. Racing handles the sustained heat cycles a circuit session imposes. Discs come drilled or slotted at the same price, and braided lines firm the pedal.

About the Hollow Front Brake Kit

The hollow-vane disc gives a greater effective surface area exposed to airflow during hard stops, cutting the thermal accumulation that leads to fade. The caliper is a hollow-body forging as standard, reducing unsprung mass at the corner while staying rigid under load. For circuit work, the optional Hollow Racing caliper deletes the dust cover, is rated to 1000C, and carries a two-year warranty.

Calipers are painted in Red, Yellow, Gold, Black, or Anodized Black at no extra cost. A Custom Color in any Pantone shade is £150. Premium polished-forged finishes come in Titanium, Polished Gold, and Polished Silver, with candy finishes in Teal, Blue, Red, and Orange, making the install a deliberate statement at events where the B4 Avant’s rarity draws attention. Centre bells can be upgraded to a two-tone anodized finish in five colours or to titanium. The kit is front-axle specific, supplied as a matched pair targeting the axle that carries the dominant share of braking force, a balance that leans further forward on the heavier Avant estate and further still on quattro variants. Everything is selectable above when you order.

Fitment for the Audi 80 B4 AVANT (1991-1996)

This kit is specified for the Audi 80 in B4 Avant estate body style, covering the 1991 to 1996 production run, the last generation of the 80 line before the A4 replaced it, and supplied as a matched front-axle pair. The B4 Avant ran across both front-wheel-drive and quattro configurations, and hub and caliper specifications can differ between variants, so confirm your drivetrain before ordering.
