XYZ Racing Hollow Front Brake Kit — Mazda 323 BG GTR 4WD (1989-1994)

The BG-generation 323 GTR arrived as Mazda’s turbocharged, four-wheel-drive homologation statement for the early 1990s rally era, a compact, grippy hatchback with genuine stage credentials baked in from the factory floor. Thirty years on, these cars are still being driven as intended, and the original front braking hardware, dimensioned for an era when circuit days were not the expected use case, is the first thing serious owners address.

The XYZ Racing front big brake kit upgrades the front axle across the full 1989-1994 BG GTR 4WD run. You receive a pair of front calipers and a pair of front discs, with three pad compounds, disc style, and caliper finish all chosen above this copy when you order, to match whatever direction the build has taken.

What this brake kit does for your 1989-1994 Mazda 323 BG GTR 4WD

The GTR’s four-wheel-drive drivetrain changes the braking equation against the standard two-wheel-drive 323. Because traction into a corner is rarely the limiting factor, you can carry meaningfully more entry speed, which lands squarely on the front brakes when it is time to slow. The hollow-vane disc handles thermal load more effectively than the stock items under repeated hard stops, and two-piece floating discs cut rotating and unsprung mass at the front. Braided lines firm the pedal by removing rubber-hose expansion, shortening pedal travel without introducing the grabby bite that makes a road car hard to drive smoothly. Three compounds, Street, Sport, and Racing, mean the setup matches actual use rather than compromising in both directions.

About the Hollow Front Brake Kit

The hollow-vane disc shaves unsprung mass from the front axle while improving heat dissipation during repeated hard braking, relevant on a car that generates genuine corner-entry speeds from its AWD traction. The front-specific configuration is engineered around the BG 323 braking geometry, mounting within the original front-axle architecture without custom brackets or hub rework. The caliper is a hollow-body forging as standard, light yet stiff, and for sustained track use the optional Hollow Racing caliper deletes the dust cover, is rated to 1000C, and carries a two-year warranty. Street is the quiet, low-dust road default, Sport adds bite and a higher heat range for mixed road and occasional track use, and Racing handles the consistently high rotor temperatures of the circuit.

Discs can be drilled or slotted at the same price, with centre bells available two-tone in five anodized colours or titanium. Included caliper colours, at no extra cost, are Red, Yellow, Gold, Black, and Anodized Black. A Custom Color in any Pantone is £150, with premium polished-forged Titanium, Polished Gold, and Polished Silver finishes and a candy range of Candy Teal, Candy Blue, Candy Red, and Candy Orange.
