Caliper render for this kit:
The sixth-generation Legacy BN is a heavy, comfortable all-wheel-drive saloon, and Subaru’s symmetrical AWD layout sends real load rearward under braking, so the back axle works harder than the car’s relaxed road manners let on. The XYZ Racing Hollow Rear Brake Kit for the Subaru Legacy BN (2014-2026) upgrades that rear corner with two-piece floating discs designed to shed weight and dump heat faster than the factory setup.
This is a rear big brake kit, a matched pair of left and right corners, for owners who load the car, on long descents, at motorway pace, or on the occasional B-road blast, and want the rear axle to keep contributing instead of fading. Pad compound runs from Street through Sport to Racing, so you match the kit to how hard you actually drive the Legacy.
What this rear brake kit does for your 2014-2026 Subaru Legacy BN
On a heavy AWD saloon the rear brakes manage pitch and stability as much as outright stopping, and that is where this kit earns its place. The two-piece floating discs cut rotating mass at the rear hub and let the friction ring expand freely, which sharpens how quickly the brakes respond and helps the car settle under trail braking rather than running wide. Better heat management keeps the pedal firm on repeated stops, the scenario where a standard Legacy BN rear setup starts to go long. Step up to the Sport or Racing pad compound for more bite and higher fade resistance under harder use, while the Street compound keeps daily refinement and low dust for a car that still does the commute. Painted caliper options, Red, Yellow, Gold, Black and Anodized Black, come at no extra cost, with a Custom Color in any Pantone available, so the hardware can match the wheels you already run.
About the Hollow Rear Brake Kit
The XYZ Racing Hollow Rear Brake Kit pairs a two-piece floating disc, where the friction ring floats against an alloy bell to lower unsprung and rotating weight while opening internal paths for airflow and heat to escape, with a hollow-cast caliper as standard. Less mass at the rear corners means the suspension has less to control, and cooler discs hold their friction coefficient longer when you brake repeatedly. The kit is offered with three pad compounds, Street for road use, Sport for fast-road and mixed driving, and Racing for track and sustained hard work, so one set of hardware covers a wide spread of use cases, with an optional Hollow Racing caliper rated to 1000C and a two-year warranty for dedicated track duty. Painted calipers come at no extra cost in Red, Yellow, Gold, Black and Anodized Black, with a Custom Pantone for £150 plus premium polished-forged and candy finishes; disc faces are drilled or slotted at the same price, and the centre bell upgrades to a five-colour anodized two-tone or titanium at checkout. As a rear-specific kit it is built to pair with a matching front upgrade or to firm up the back axle of an otherwise standard car.
Fitment for the Subaru Legacy BN (2014-2026)
This kit is cut for the Subaru Legacy BN across the 2014 to 2026 model run, the sixth-generation chassis, and fits the rear axle specifically. Confirm your exact build and wheel clearance against the spec before ordering, since caliper and disc sizing assume the standard BN rear hub.

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 330–356mm (rear). 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.
