Caliper render for this kit:
The BM9 saloon and BR9 estate carry their symmetrical all-wheel-drive mass with a rearward bias that the standard rear discs were never sized to manage on repeat stops. This XYZ Racing Hollow Rear Brake Kit for the Subaru Legacy BM9/ BR9 (2009-2014) puts a 290mm rear disc behind each rear wheel, giving the back axle the thermal headroom the EJ-powered GT chassis asks for once you start using the brakes in anger.
It is a rear-specific upgrade, a matched pair of left and right corners, built around the Legacy’s drum-in-hat parking brake, retaining the 191mm internal handbrake so the factory cable and mechanism still work. The two-piece floating disc sheds heat and rotating mass at the corner that matters most for an AWD car that shifts load aft under deceleration.
What this brake kit does for your 2009-2014 Subaru LEGACY BM9/ BR9 φ 290/ φ 191
The larger 290mm rear disc adds swept area and heat capacity, so the rear axle stops contributing to pedal fade on a downhill B-road or a string of hard stops. On an all-wheel-drive Legacy that throws weight backwards under braking, a stronger rear end keeps the car settled rather than nose-diving, which steadies the platform into a corner. Pad compound is your call: the Street option suits everyday driving with low dust, the Sport compound bites harder when warm for fast road and the odd track day, and the Racing compound holds friction at the temperatures a track session or a quick estate full of gear will generate. The result is a firmer, more confident pedal and a rear axle that finally pulls its share.
About the Hollow Rear Brake Kit
This is a rear big brake conversion sized specifically to the Legacy’s 290mm/191mm dimensions, not a universal caliper bolted to an adaptor. The two-piece floating disc cuts unsprung and rotating mass while letting the friction ring expand against an alloy bell to manage heat under sustained load. It mates a fixed performance caliper, a hollow-cast forging as standard, to the 290mm rear rotor while preserving the 191mm drum-in-hat parking brake the BM9/BR9 relies on for its handbrake. Three pad compounds, Street, Sport and Racing, let you match friction to use, from commuting to circuit work, with an optional Hollow Racing caliper rated to 1000C and a two-year warranty for dedicated track duty. Calipers are painted Red, Yellow, Gold, Black or Anodized Black at no extra cost, with a Custom Color in any 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, so the upgrade reads as deliberate behind an open wheel.

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.
