Caliper render for this kit:
The fifth-generation Legacy’s growth in platform scale, wider, heavier and more refined than the generation it replaced, is what made the BM9 saloon and BR9 estate both more comfortable and more demanding of their braking hardware. Subaru’s symmetrical all-wheel drive places considerable mass over the front axle, and that mass becomes apparent when you are asking the front brakes to scrub speed repeatedly on a demanding road or circuit.
The XYZ Racing Hollow Front Brake Kit gives the BM9/BR9 a step-up in front-axle capacity beyond the OEM hardware. It is a single-axle kit, a matched pair of front calipers and two-piece floating discs for the left and right corners, with pad compound, disc style and caliper finish all chosen when you order so the same kit covers daily road use through to circuit days.
What this brake kit does for your 2009-2014 Subaru LEGACY BM9/ BR9
The hollow-vane disc at the heart of this kit creates internal airflow channels that draw heat away from the pad-contact surface during sustained deceleration, shedding it into the airstream rather than soaking it into solid iron. On an AWD platform carrying the Legacy’s kerb weight, fade resistance matters more than on a lighter, two-wheel-drive car, since the front discs absorb the majority of kinetic energy regardless of how the drivetrain distributes traction. The two-piece floating discs pair an aluminium centre bell with an iron friction ring, holding the disc true through repeated heat cycles and trimming rotating mass at the wheel, while braided stainless lines give a firmer pedal than rubber hoses that swell under load.
Three pad compounds let the kit serve different uses. Street is the quiet, low-dust road default; Sport sharpens initial bite for fast A-road work and the occasional track day; Racing is a full circuit compound for lap sessions. Choose by how the car is used rather than accepting a single-compound compromise.
About the Hollow Front Brake Kit
The kit takes its name from the disc’s internal ventilation. Hollow-vane channels run through the rotor body and create dedicated passages for airflow across the swept face, reducing pad and disc temperatures under sustained braking loads. The calipers are hollow-body as standard for stiffness without excess weight, supplied as a left-and-right pair, and the front-axle application reflects the straightforward physics that braking load is front-weighted regardless of whether the driven axle is front, rear or all four corners.
Discs come drilled or slotted at the same price, so you can choose on looks or wet-weather feel. Included caliper finishes are Red, Yellow, Gold, Black and Anodized Black at no extra cost, with a Custom Color to any Pantone code for a small upcharge, a practical consideration on a car that often functions as both a daily driver and a show vehicle. Premium polished-forged finishes (Titanium, Polished Gold, Polished Silver) and candy finishes (Candy Teal, Candy Blue, Candy Red, Candy Orange) sit in a separate upgrade tier. Two-tone centre bells in five anodized colours, or a titanium bell, are selectable at checkout. For serious track use there is an optional Hollow Racing caliper, run without a dust cover, rated to 1000C and backed by a two-year warranty.
Fitment for the Subaru LEGACY BM9/ BR9 (2009-2014)
This front brake kit is confirmed for the Subaru Legacy across both the BM9 saloon and BR9 Touring Wagon body styles, covering the full 2009 to 2014 production span, and fits the front axle as a left-and-right pair. Both variants share the same front suspension and brake architecture throughout this generation. Confirm your OEM caliper bolt pattern and disc diameter against the kit specification sheet 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.
