XYZ Racing Hollow Rear Brake Kit — Subaru FORESTER φ 315/ φ 191 (2008-2012)

The third-generation SH Forester carries its mass high and well aft of the front axle, so the rear brakes do more honest work than the tall-wagon silhouette suggests, particularly on a turbocharged 2.5XT loaded for a long descent or a track session. This XYZ Racing rear brake kit fits a matched pair of 315mm two-piece floating discs and hollow-cast calipers to the back axle of the 2008-2012 Subaru Forester, exactly where the factory setup runs short of thermal headroom first.

The discs pull weight out of the rear corners without surrendering clamping area, which matters on a car that already asks its AWD driveline and dampers to manage a fair amount of body mass. Street, Sport and Racing pad compounds let you set the rear bias to how the car is actually driven, from towing and daily duty through to repeated hard stops on circuit.

What this big brake kit does for your 2008-2012 Subaru Forester

On a Forester that tips past 1,500kg with a full tank and AWD hardware, rear brake temperature is the quiet limit on a downhill run or a busy track lap. The 315mm rear disc adds swept area and heat capacity so the pedal stays firm after consecutive stops instead of going long. The φ 191 centre dimension keeps the rotor sized correctly to the SH rear hub, and the two-piece floating disc trims unsprung mass at each rear corner, which helps the dampers control the tall body over kerbs and broken surfaces. Pick the Racing compound and the rear axle holds its bite through a session; choose Street pads and you keep quiet, cold-stop manners for everyday use, with Sport between the two for fast road.

About the rear big brake kit

The kit is built around a 315mm two-piece floating disc whose hollow-vane internal structure removes weight while keeping the swept area you need, mounted to a 191mm centre that suits the Forester’s rear geometry, and a floating bell that lets the friction ring expand under heat without warping. Disc faces come drilled or slotted at the same price, chosen when you order. Three pad compounds cover the spread of use cases, Street for stock-feel replacement, Sport for fast-road bite with manageable dust and noise, and Racing for sustained high-temperature work. The caliper bodies are hollow-cast as standard, removing material from non-load paths to cut weight while keeping piston area and stiffness intact, with an optional Hollow Racing upgrade for dedicated track cars that removes the dust cover, is rated to 1000C and carries a two-year warranty. Caliper finishes are offered in Red, Yellow, Gold, Black and Anodized Black at no extra cost, with a custom Pantone option, so the rear hardware can be matched or deliberately contrasted behind the wheels. The whole package is engineered to raise rear thermal capacity on a heavy AWD platform rather than simply enlarge the disc for show.
