Caliper render for this kit:
The SG Forester shares platform architecture with the Impreza family but sits considerably higher on its suspension, and that raised centre of gravity shifts the front-axle workload during hard braking. In the XT turbocharged variants, where the engine’s output pushes performance well beyond what the standard front caliper and disc combination was designed for, fade and pedal-travel creep on long descents are familiar frustrations.
The XYZ Racing Hollow Front Brake Kit addresses that front-axle deficit directly. It is a single-axle kit, a matched pair of front calipers and two-piece floating discs for the left and right corners, configured to how you use the car: a genuine daily-driver upgrade without over-specifying, with a circuit compound there for when the road gets serious.
What this brake kit does for your 2003-2007 Subaru FORESTER
The two-piece floating discs pair an aluminium centre bell with an iron friction ring, cutting rotating mass and improving thermal capacity over the solid OEM rotors. On a car that can approach 1,500kg in turbocharged trim, that heat management pays off in pedal consistency through prolonged hard stops, and the hollow-vane disc draws cooling air through the rotor body so heat sheds continuously instead of soaking in. Subaru’s AWD layout concentrates stopping load through the front axle regardless of conditions, so a larger swept area and the right compound feed directly into shorter distances and a firmer, more linear pedal. Less rotating and unsprung weight also keeps the suspension settled over surface changes.
Three pad compounds match the friction to the use. Street is the quiet, low-dust road default; Sport sharpens bite and adds heat range for fast-road driving with the occasional track day; Racing is a full circuit compound that handles the higher sustained temperatures of circuit or stage-road use. Braided stainless lines are included for a firmer, more repeatable pedal than rubber hoses that swell under pressure.
About the Hollow Front Brake Kit
The hollow-vane design channels airflow through the disc body, reducing the thermal gradient across the rotor face that causes conventional rotors to warp under repeated high-load stops. Cooling channels run through the rotor and draw air across the friction surfaces while the wheel turns, so heat sheds into the airstream rather than building with nowhere to go. The calipers are hollow-body as standard for stiffness without excess weight, and the kit covers the front axle as a pair, where the SG Forester does the bulk of its braking work.
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. 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 FORESTER (2003-2007)
This XYZ Racing front brake kit covers the Subaru Forester across the 2003 to 2007 model years, encompassing both naturally aspirated and turbocharged XT variants in the SG-generation production window, and fits the front axle as a left-and-right pair. Buyers specifying to XT or Forester STI configuration should verify brake-line routing against their exact variant 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.
