Caliper render for this kit:
The GC8 Impreza STI’s symmetrical AWD sends the car into corners with more front-axle load than a comparable two-wheel-drive sports car generates, and trail braking is the technique that exploits it, which is exactly where the factory brake setup reveals its limits under sustained hard use. On a fast B-road or in a tight circuit section, fade at the nose undermines that well-documented ability to rotate the car, and lengthening pedal travel under repeat stops removes confidence at the worst possible moment.
The XYZ Racing Hollow Front Brake Kit for the Subaru Impreza STI covers the 1997-2000 generation and addresses that directly. It is a single-axle kit, a matched pair of front calipers and two-piece floating discs for the left and right corners, with the hollow-vane disc reducing thermal soak under sustained braking and pad compound, disc style and caliper finish all chosen to match your use.
What this brake kit does for your 1997-2000 Subaru Impreza STI
On the GC8, the front brakes carry significant load, not just from the car’s mass but from the way most STI owners drive: deep, late, and often trail-braking to exploit the AWD’s rotation into corners. The hollow-vane disc draws cooling air through the rotor body so heat sheds continuously, maintaining consistent pedal feel where a solid disc would soften and lengthen under repeat stops. The two-piece floating discs pair an aluminium centre bell with an iron friction ring, holding the disc true through repeated heat cycles and trimming rotating mass at the wheel, which keeps the front end sharp on turn-in. Braided stainless lines are included for a firmer, more repeatable pedal than rubber hoses that swell under pressure.
Three pad compounds give a genuine choice. Street is the quiet, low-dust road default for daily and occasional spirited use; Sport adds bite and heat range for fast roads with the occasional track day; Racing is a full circuit compound rated for track and hillclimb sessions where heat generation is sustained.
About the Hollow Front Brake Kit
Built around the hollow-vane disc, the kit manages the thermal load that accumulates during sustained hard braking, exactly the kind the GC8’s AWD traction and deep late-braking style makes easy to generate. Cooling channels run through the rotor body and draw air across the friction surfaces while the wheel turns, so heat sheds into the airstream rather than soaking into solid iron. The calipers are hollow-body as standard for stiffness without excess weight, supplied as a left-and-right pair covering the front axle.
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 Impreza STI (1997-2000)
This kit is confirmed for the GC8-generation Subaru Impreza STI built between 1997 and 2000 and fits the front axle as a left-and-right pair. GC8 production across this period included several sub-variants with differing OEM brake specifications, so verify your chassis variant and existing caliper configuration before ordering to ensure correct fitment.

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.
