XYZ Racing Hollow Front Brake Kit — Audi A4 B6 (2002-2004)

The B6 A4’s front brake specification was drawn up for a car Audi expected to spend its life in traffic and on motorway runs. Reasonable for the majority, but a liability the moment you use a 1.8T or 3.0 V6 hard through the mountains or round a track. The XYZ Racing front brake kit addresses that gap directly, swapping the stock front hardware for a setup with the thermal headroom the original equipment lacks.

This is a front-axle upgrade: a matched pair of left and right front calipers with two-piece floating discs. Three pad compounds give buyers a genuine choice based on how they plan to use the car rather than a forced compromise, and the disc, finish and centre-bell options are all set when you order.

What this brake kit does for your 2002-2004 Audi A4 B6

The B6’s front-biased weight distribution, particularly in quattro form, puts a disproportionate demand on the front brakes. The standard setup copes at road speeds but fades under repeated hard stops, exactly the situation owners hit after a few laps or a mountain pass with sustained downhill braking. The larger two-piece disc increases swept area and the uprated caliper increases clamping force, while the hollow-vane disc design sheds heat faster than a solid casting between stops. Lighter two-piece discs trim rotating and unsprung mass at the front, and braided lines hold the pedal firm under load. The Racing compound keeps pedal feel at temperatures where a road pad would struggle; Sport gives more progressive initial bite on a cold disc than a track-only pad allows; Street is the quiet, low-dust road default. 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 kit centres on a larger-diameter two-piece floating front disc paired with an uprated caliper that bolts to the B6 A4’s existing front hub, making it a clean upgrade without modification to the subframe or steering geometry. Three friction compounds span light daily use through to sustained track sessions: Street, Sport and Racing, each matched to a real use profile. 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, which matters on the B6 A4’s typical wheel fitments where brake hardware sits clearly visible behind the spokes. The kit targets the front axle, the end of the car carrying the majority of braking effort under any meaningful load.
