Caliper render for this kit:

The SJ Forester 2.0XT puts a turbocharged FA20 and full-time symmetrical all-wheel drive under a tall, family-sized body, and that combination loads the rear axle harder under braking than the crossover looks suggest. The XYZ Racing rear brake kit for the Subaru Forester 2.0XT (SJ) targets exactly that: a matched pair of φ278 two-piece floating rear discs whose hollow-vane construction sheds heat and unsprung weight where the standard setup runs out of thermal headroom first.
This is a rear upgrade built for fast-road use and the kind of repeated stops a heavy AWD turbo wagon generates on a quick B-road or a long descent. With three pad compounds and a choice of caliper finishes, you spec the bite and the look to suit how you actually drive the 2014-2018 Forester.
What this big brake kit does for your 2014-2018 Subaru Forester 2.0XT
Fit it and the first thing you notice on the 2014-2018 Subaru Forester 2.0XT is a firmer, more linear pedal, as the larger φ278 rear rotor gives the system more swept area to work with. The two-piece floating disc design cuts rear unsprung mass, which lets the rear suspension settle faster over broken surfaces and keeps the back axle composed when you trail the brakes into a corner. Heat is the real gain: a tall, heavy AWD wagon cooks its rear brakes on long descents and under load, and the extra thermal capacity here resists the fade that turns a soft factory pedal vague. The Racing compound adds initial bite for track or hard road work, Sport sits in the middle for fast road, while the Street pad keeps the daily commute quiet and low on dust. Across the board you get more stopping confidence without upsetting the Forester’s stable, planted character.
About the rear big brake kit
The XYZ Racing rear brake kit is a rear-axle big brake upgrade designed around a φ278 two-piece floating disc whose hollow-vane internal structure removes rotational and unsprung weight without giving up structural strength. The hollow construction lowers the mass the brakes have to spin up and helps the disc shed accumulated heat between stops, which is what keeps performance consistent when you start asking for the brakes repeatedly, and the floating mount lets the friction ring expand under heat without warping its alloy bell. Disc faces come drilled or slotted at the same price, chosen when you order. The kit comes with a choice of three pad compounds, Street for everyday driving, Sport for a sharper road bite, and Racing for sustained high-temperature work, so the same hardware suits a daily Forester or a more committed build. The caliper bodies are hollow-cast as standard, with an optional Hollow Racing upgrade for track-focused cars that removes the dust cover, is rated to 1000C and carries a two-year warranty. Caliper finishes run Red, Yellow, Gold, Black and Anodized Black at no extra cost, with a custom Pantone match available, letting the kit sit discreetly behind the standard wheels or read as part of a wider visual upgrade. It is a bolt-on rear setup engineered to pair with a front big brake kit or to address the rear bias of a heavy AWD platform on its own.
Fitment for the Subaru Forester 2.0XT (SJ) (2014-2018)
This kit is mapped to the SJ-generation Subaru Forester 2.0XT built between 2014 and 2018, the turbocharged FA20 model in the range. The φ278 rear rotor sizing is specific to this chassis and trim, so confirm your car is the 2.0XT SJ rather than a naturally aspirated Forester of the same era 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 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.
