Caliper render for this kit:
The XYZ Racing front brake kit for the BMW 4 Series G26 Gran Coupe addresses a genuine front-axle limitation: the factory brake specification runs out of thermal reserve before the G26’s available performance does. In M440i xDrive and M4 Competition xDrive form, the G26 is a heavy platform; that four-door CLAR body in all-wheel-drive configuration carries real kerb mass through the front subframe, and the OEM brakes manage it fine on the road but betray themselves under sustained circuit conditions.
This kit gives the front axle the braking performance the G26’s drivetrain capability actually calls for. It is a single-axle upgrade, a matched pair of front calipers and discs. Three pad compounds and a full range of caliper finishes let buyers spec the installation to the car’s actual use case and its typically generous wheel specification.
What this brake kit does for your 2020-2026 Bmw 4 Series G26 (2WD/4WD)
Two-piece floating disc construction reduces rotational inertia at each front corner, and on a platform where xDrive hardware already adds weight forward of the firewall, that reduction matters. The aluminium centre bell lets the friction ring expand cleanly under heat without distorting, and hollow-vane internals draw air through the disc body. Less rotating mass means the front brakes develop initial bite faster and recover thermal capacity between stops more effectively than the OEM equivalent. The pedal behaviour stays linear further into a braking event rather than softening progressively as disc temperatures climb.
The three compounds give owners a genuine specification choice. Street is the quiet, low-dust default that suits mixed driving; Sport is the right pick for a G26 that sees occasional track days, with more bite and heat range; Racing is for structured circuit use where brake temperatures are predictably high. Caliper colour acknowledges that the G26’s 20-inch-plus wheel packages often make the calipers a visible design element.
About the XYZ Racing Hollow Front Brake Kit
The XYZ Racing caliper is built on a hollow body as standard, with a two-piece floating disc that manages heat more effectively than OEM cast iron while reducing rotating mass at the front axle. The construction delivers lower rotational inertia without sacrificing structural integrity under repeated hard braking. Three pad compounds, Street, Sport, and Racing, position this kit across a genuine use-case range, from a daily-driven Gran Coupe that sees occasional spirited road use through to a car running structured track sessions.
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) reflect the premium specification G26 owners typically bring to their builds. The Hollow Racing caliper upgrade (no dust cover, rated 1000C, two-year warranty) and braided lines suit serious track use. Front fitment is the priority upgrade position on the G26: weight transfer under hard deceleration loads the front axle heavily, and that is where sustained brake performance determines whether the car’s handling balance holds cleanly through the stop.
Fitment for the Bmw 4 Series G26 (2WD/4WD) (2020-2026)
This front brake kit covers the BMW 4 Series G26 Gran Coupe in both rear-wheel-drive and xDrive configurations from 2020 to 2026. The 2WD/4WD compatibility is relevant for the UK market, where a significant proportion of G26s are specified in xDrive form, M440i xDrive and M4 Competition xDrive in particular. Confirm your existing hub specification and disc diameter against the product listing 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.
