Caliper render for this kit:

The fourth-generation Mazda 3 arrived with a chassis more honest than its price point suggests. The hatchback’s rear geometry, progressive front MacPherson setup, and a steering system genuinely designed to communicate all conspire to make the BP3 one of the more rewarding driver’s tools in its class. Stock front brakes, adequate for their stated brief, were calibrated against everyday use rather than the repeated, hard stopping a fast B-road or a track day generates.
This XYZ Racing front big brake kit replaces the standard front setup with larger-diameter hardware, a logical extension of what the BP3’s chassis already asks of its driver. You receive a pair of front calipers and a pair of front discs, with three pad compounds, disc style, and caliper finish all chosen above this copy when you order, from spirited fast-road work through to structured circuit sessions.
What this brake kit does for your 2019-2026 Mazda 3 (BP)
Larger front discs address the weak link in the standard package: thermal capacity under pressure. The higher-output BP3 variants, the 178bhp SkyActiv-X and the 225bhp 2.5 Turbo, build speed readily enough to expose the fade window in standard front hardware during a track day or a committed run on a demanding A-road. The hollow-vane rotor manages heat more effectively across repeated stops, carrying more surface area relative to its mass. Two-piece floating discs cut rotating and unsprung mass at the front, and braided lines firm the pedal by removing rubber-hose expansion. Circuit use becomes realistic with the Racing compound, while Sport delivers sharper pedal feel without sacrificing everyday usability and Street is the quiet, low-dust default.
About the Hollow Front Brake Kit
The hollow-vane disc removes material in a deliberate pattern to reduce mass and improve thermal cycling, keeping temperatures in a workable range across repeated hard-braking events. Configured for the front axle, where the BP3’s FWD layout concentrates braking forces under hard deceleration, the kit is built around the demands the platform’s higher-output variants create. The caliper is a hollow-body forging as standard, light yet stiff, and for circuit use the optional Hollow Racing caliper deletes the dust cover, is rated to 1000C, and carries a two-year warranty. Three pad compounds span Street, Sport, and Racing, each tuned to a different operating window, and a big-brake specification means a larger-diameter rotor than original equipment, increasing braking leverage and thermal mass before fade sets in.
Discs can be drilled or slotted at the same price, with centre bells available two-tone in five anodized colours or titanium. Included caliper colours, at no extra cost, are Red, Yellow, Gold, Black, and Anodized Black. A Custom Color in any Pantone is £150, with premium polished-forged Titanium, Polished Gold, and Polished Silver finishes and a candy range of Candy Teal, Candy Blue, Candy Red, and Candy Orange.
Fitment for the Mazda 3 (BP) (2019-2026)
Designed for the Mazda 3 BP platform across the full 2019-2026 production run, covering both the four-door sedan and five-door hatchback on the shared SkyActiv architecture. Owners on lower trims running factory 16-inch alloys should confirm wheel spoke clearance against the caliper housing before ordering; the larger caliper body may require a minimum 17-inch rim depending on spoke profile.

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.
