Caliper render for this kit:
The G82 M4 Coupe carries considerably more mass than the F82 generation it replaced, and at the end of a long straight on track, Donington’s Melbourne hairpin, the approach to The Mountain at Cadwell Park, that extra weight registers most clearly in the braking zone. BMW’s own hardware is substantial, but the S58’s sustained output means the OEM setup is working at the edge of its thermal envelope through repeated hard sessions, and fade is a real consequence once temperatures have built.
Aimed at owners who have reached that thermal ceiling, the XYZ Racing front brake kit for the BMW 4 Series G82 M4 Coupe is a single-axle upgrade, a matched pair of front calipers and discs, bringing two-piece floating discs to the primary braking axle, with three pad compounds that let the specification be matched to the car’s actual use, from daily road miles through to full circuit days.
What this brake kit does for your 2021-2026 Bmw 4 Series G82 M4 Coupe
Reduced rotating mass at the front axle gives the S58 less inertia to overcome under braking, contributing to shorter stopping distances from high speed. Two-piece floating disc construction improves thermal management through extended sessions, dissipating heat more efficiently than a comparable solid disc under repeated hard stops, with an aluminium centre bell that lets the friction ring expand cleanly under heat and hollow-vane internals that draw air through the disc body.
The three compounds cover the full operating range: Street maintains NVH and cold-bite behaviour close to factory specification while staying quiet and low-dust, Sport suits mixed road-and-track use with more bite and heat range, and Racing operates at a higher temperature window, unlocking stopping performance that the OEM pad, designed around longevity and MOT compliance, cannot deliver.
About the Hollow Front Brake Kit
The XYZ Racing caliper is built on a hollow body as standard, with a two-piece floating disc whose internal construction reduces mass while maintaining the rigidity required for repeated high-energy stops. The three-compound pad range, Street, Sport, and Racing, means the same physical kit can be configured across very different operating conditions without needing a separate setup.
Discs come drilled or slotted at the same price, and the centre bell can be specified two-tone in five anodized colours or in titanium. Caliper colour is painted at no cost in Red, Yellow, Gold, Black, or Anodized Black; Custom Color matches any Pantone for £150; and premium polished-forged (Titanium, Polished Gold, Polished Silver) and candy finishes (Candy Teal, Candy Blue, Candy Red, Candy Orange) take the look to show grade, allowing the installation to complement or contrast the G82’s exterior. The Hollow Racing caliper upgrade (no dust cover, rated 1000C, two-year warranty) and braided lines suit serious track use. As a front-only fitment, the kit concentrates the upgrade where the G82 M4 does its most demanding braking work: the front axle under hard trail-braking carries significant load in a car of this power and weight, particularly through the compression into slow-speed corners.

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.
