XYZ Racing Hollow Front Brake Kit — Bmw 5 SERIES E 39 M5 (1998-2003)

The E39 M5 arrived in 1998 with Brembo-sourced four-pot front calipers and 345mm discs, a serious brake specification for a saloon of its era. What that setup was not designed to absorb indefinitely is the combination of time-related component degradation and the sustained thermal load that track-day use through tight, stop-start circuits puts into around 1,800kg of V8 saloon.

This XYZ Racing Hollow front big brake kit for the 1998-2003 BMW 5 Series E39 M5 provides a current-spec upgrade path: a single-axle front kit, a left and right pair of calipers on two-piece floating discs, with three pad compounds, Street, Sport, and Racing, matched to how the car genuinely gets used. Everything is set at the configurator above.

What this brake kit does for your 1998-2003 Bmw 5 Series E 39 M5

The two-piece floating disc improves sustained cooling through its internal vane geometry under repeated heavy stops, directly relevant on a car of the E39 M5’s kerb weight, where brake energy loads are high across the front axle, while reducing unsprung and rotating mass and letting the friction ring expand without coning. The Street pad is the quiet, low-dust road default; the Sport compound balances cold bite against thermal stability for mixed road and occasional circuit use; the Racing compound demands temperature to work, but under the sustained loading a Cadwell Park or Donington session places on an S62-powered saloon, the reward is repeatable, fade-resistant retardation. Caliper finish, from the included no-cost painted colours through to premium polished and candy options, is a visible choice through the alloys on a car people look at.

About the Hollow Front Brake Kit

The XYZ Racing Hollow front brake kit centres on a hollow-bodied caliper as standard and a two-piece floating disc, a geometry that differs from a conventional one-piece vented rotor in how internal channels manage airflow under sustained load. Three pad compounds are offered from the outset: Street for road-focused use with minimal circuit exposure; Sport for the mixed fast-road and occasional-track majority; and Racing for owners who want friction material that matches what the S62’s outputs keep loading into the front axle across an afternoon of circuit driving. For hard, repeated track use the optional Hollow Racing caliper deletes the dust cover, is rated to 1000C, and carries a two-year warranty. Disc style is drilled or slotted at the same price, centre bells upgrade to two-tone anodized in five colours or to titanium at checkout, and caliper colour finishes span the included Red, Yellow, Gold, Black, and Anodized Black, a Custom Color in any Pantone, premium polished Titanium, Polished Gold, and Polished Silver, and candy Teal, Blue, Red, and Orange. The kit covers the front axle only.

Fitment for the Bmw 5 Series E 39 M5 (1998-2003)

This kit is specified for the E39-generation M5, covering the full 1998-2003 production run of the S62-powered saloon. It is an M5-specific fitment, not a universal E39 five-series listing, so confirm the variant and build year before ordering.
