Fits Bmw 3 SERIES G 20 (2WD/4WD) (2019-2026)

Brake pad compound

Street: quiet, low-dust, strong cold bite for road driving. Sport: higher temperature range and more bite for fast road and occasional track. Racing: maximum fade resistance for sustained track use (noisier and dustier cold). Match the pad to how hard you actually brake.

Disc size

Caliper grade

Hollow is the standard caliper: a lighter hollow-body forged caliper with a dust cover and a 5-year warranty. Hollow Racing drops the dust cover for sustained high-temperature use (rated to 1000°C, 2-year warranty) — the track-grade choice.

Caliper colour

Painted colours are included. Polished-forged finishes are mirror-polished forged calipers (Titanium, Gold, Silver); candy colours are a deep, mirror-reflection paint. Both are premium upgrades — fuller detail further down the page.

Disc style

Drilled discs (cross-drilled holes) vent gas and water and look aggressive; slotted discs (surface grooves) wipe the pad face clean and resist fade under sustained hard use. Same price — choose on looks or how you drive.

Centre bell

The centre bell is the CNC-machined aluminium hat that joins the disc to the hub. Standard anodized is included; a two-tone bell adds an anodized accent ring in your choice of colour; titanium is the lightest, forged option.

Carbon-ceramic rotor

Carbon-ceramic rotors are a special-order track upgrade: far lighter than steel, fade-resistant at extreme temperatures and extremely long-lived. The price follows the disc size you choose above. The standard two-piece steel rotor is included.

XYZ Racing Hollow Front Brake Kit — Bmw 3 SERIES G 20 (2WD/4WD) (2019-2026) — 356 mm
356 mm

The G20 3 Series arrived with genuine driver’s-car credentials: tighter body control than the F30, more steering feel, and on M340i spec, 374bhp available to either the rear wheels or xDrive’s four-wheel grip. What the standard front brakes were not designed for is the sustained, repeated stops that come with circuit work or committed B-road driving, where disc temperature climbs progressively with each application. The XYZ Racing front brake kit addresses exactly that window.

Both rear-wheel-drive and xDrive G20s are covered by this single-axle fitment, a matched pair of front calipers and discs, and that matters more than it might initially appear. The 4WD variants carry additional mass over the front axle, with transfer case, prop shaft, and front differential hardware all ahead of the firewall, meaning heat accumulates faster at the front calipers under repeated heavy braking. A big brake kit here is a more direct solution than compound swaps alone.

What this brake kit does for your 2019-2026 Bmw 3 Series G20

Two-piece floating disc construction reduces rotating mass at the front axle, sharpening the G20’s already communicative steering response precisely where braking and turn-in overlap. The aluminium centre bell lets the friction ring expand cleanly under heat without distorting, and hollow-vane internals draw air through the disc body to keep temperatures down.

Three compounds span the realistic use spectrum: Street is the quiet, low-dust default with improved bite and fade resistance over the factory setup; Sport adds more bite and heat range for fast-road driving; and Racing is calibrated for sustained elevated temperatures during circuit sessions. Caliper finish allows the kit to complement the G20’s factory M Sport blue or contrast against it deliberately.

About the XYZ Racing Hollow brake kit

The XYZ Racing caliper is built on a hollow body as standard, an uprated braking system designed to exceed the thermal and mechanical limitations of the BMW G20’s production-spec front axle setup. The two-piece floating disc prioritises heat dissipation and rotating-mass reduction, two factors that become significant when the car is driven hard repeatedly rather than occasionally. Pad compound choice across three specifications means the kit performs as a daily-driven upgrade with the Street or Sport compound fitted, or in sustained anger with the Racing specification.

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. The Hollow Racing caliper upgrade (no dust cover, rated 1000C, two-year warranty) and braided lines suit serious track use, so the result looks considered rather than merely functional.

Fitment for the Bmw 3 Series G20 (2019-2026)

This front brake kit is designed for the BMW 3 Series G20 platform across the full 2019 to 2026 production span, covering both the rear-wheel-drive (2WD) and xDrive all-wheel-drive (4WD) driveline variants within the same fitment. Confirm your chassis build sheet matches the G20 generation 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.
