XYZ Racing Hollow Front Brake Kit — Subaru IMPREZA GDB (WRX) (2000-2007)

The GDB-chassis WRX carries its turbocharged flat-four well forward and low in the engine bay, a layout that pushes more stopping load onto the front axle than the car’s symmetrical AWD system might imply. Under sustained hard deceleration, across repeated sprint-day runs or a long track session, the standard front setup reaches its limits before the chassis does. The WRX has always had more happening at the front end than its original brakes were spec’d to match.

The XYZ Racing Hollow Front Brake Kit gives the 2000-2007 Impreza GDB WRX a braking system that keeps pace with the rest of the car. It is a single-axle kit, a matched pair of front calipers and two-piece floating discs for the left and right corners, with pad compound, disc style and caliper finish all chosen to match your use, and the hardware sized to sit cleanly inside the wheel rather than fight the aesthetics you have already committed to.

What this brake kit does for your 2000-2007 Subaru IMPREZA GDB (WRX)

With the front axle carrying the GDB’s primary braking workload, a properly sized kit delivers an immediate change in character: more linear pedal response, a firmer bite point that does not migrate as temperatures climb, and consistent feel whether you are braking from motorway speed on a circuit straight or scrubbing speed for a late-apex hairpin. The hollow-vane disc draws cooling air through the rotor body so heat sheds continuously, and the two-piece floating discs pair an aluminium centre bell with an iron friction ring to hold the disc true through repeated heat cycles while trimming rotating mass at the wheel. Stopping distances from high speed shorten, and the pedal gains the firmness that makes modulation accurate rather than approximate.

Three pad compounds mean you do not need a separate track-day setup to use the full capability of this kit, you swap pads rather than calipers when the use case changes. Street is the quiet, low-dust road default; Sport adds bite and heat range for fast roads and the occasional track day; Racing is a full circuit compound for those running events with regularity. Braided stainless lines are included for a firmer, more repeatable pedal than rubber hoses that swell under pressure.

About the XYZ Racing Hollow Brake Kit

The hollow-vane name describes the disc’s internal ventilation. Cooling channels run through the rotor body and draw air across the friction surfaces while the wheel turns, so heat clears into the airstream rather than soaking into solid iron. The calipers are hollow-body as standard for stiffness without excess weight, and the front-only application is deliberate: the GDB WRX platform places the majority of its braking load on the front axle, and that is where the meaningful upgrade lives.

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 GDB (WRX) (2000-2007)

This kit covers the GDB-chassis Impreza WRX across the full 2000-2007 production span, taking in the bug-eye, blob-eye and hawk-eye body generations, all of which share the same core front braking architecture, and fits the front axle as a left-and-right pair. The GDB designation distinguishes this application from both the earlier GC8-chassis car and the GH/GE-generation Impreza that arrived from 2008 onwards. If your car sits near either boundary of that production window, confirm your chassis code before ordering.
