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

The Mazda 323 BG GTX was a homologation exercise in disguise, a turbocharged, all-wheel-drive hot hatch Mazda built partly to satisfy Group A rally requirements in the early 1990s. Production numbers were modest, surviving examples fewer still, and the owners who push these machines today know what the original brakes were sized for: road speeds, not the sustained thermal load a turbocharged 4WD chassis generates under hard driving. The XYZ Racing front big brake kit upgrades the front axle, where the BG GTX concentrates most of its braking load.

You receive a pair of front calipers and a pair of front discs, with pad compound, disc style, and caliper finish all chosen above this copy when you order. The standard 323 BG GTX hardware was adequate when the car was new, but it was specified against the tyres of the era. Contemporary rubber and the way a GTX gets driven in enthusiast hands place very different demands on the system.

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

Fitting an upgraded front kit to the turbocharged 4WD GTX delivers measurably greater fade resistance where the original hardware runs short of headroom, with front-axle heat build-up under repeated hard stops the familiar limiting factor. The hollow-vane disc sheds that heat faster than a solid item, two-piece floating discs cut rotating and unsprung mass at the front, and braided lines firm the pedal by removing rubber-hose expansion. Three pad compounds match the friction material to actual use: Street is the quiet, low-dust road default, Sport extends fade resistance for spirited fast-road use, and Racing handles the thermal loads circuit work demands.

About the Hollow Front Brake Kit

The kit targets the front axle of platforms where thermal load and mechanical stress concentrate at one end. On the BG GTX that means a turbocharged engine driving through an AWD drivetrain, with the front brakes handling the majority of deceleration load under hard stops. The caliper is a hollow-body forging as standard, light yet stiff, and for regular track outings the optional Hollow Racing caliper deletes the dust cover, is rated to 1000C, and carries a two-year warranty. The three grades, Street, Sport, and Racing, mean a single kit covers daily road use through to circuit work without swapping hardware between events.

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.
