XYZ Racing Hollow Rear Brake Kit — Mazda 323 (1989-1994)

Hard, repeated stops are where the BG-generation Mazda 323 shows its age at the back axle. This was a light, front-biased hatchback and saloon built when rear braking was an afterthought on all but the rally-bred turbo variants, and the original rear setup fades and goes wooden long before the front has given its best. The XYZ Racing Hollow rear brake kit addresses exactly that imbalance.

This is a rear-axle upgrade for the 1989-1994 Mazda 323, a pair of rear calipers and matched discs built to restore proper bias and bite to a car that rewards momentum and a settled back end. It is aimed at owners running fast-road and track miles who want the rear of the car to keep working when the pace climbs, rather than handing all the load to the front.

What this brake kit does for your 1989-1994 Mazda 323

The most obvious gain is a firmer, more linear pedal that holds its character as the discs heat up, instead of going soft after a few committed stops. A stronger, more consistent rear contribution helps the 323 stay flat and stable under trail-braking, so the nose tucks in rather than washing wide into the apex. Pad compound choice tunes that feel directly. The Street compound is the quiet, low-dust road default; the Sport compound adds bite and a wider heat range for fast road with the occasional track session; and the Racing compound is the dedicated track compound for repeated hard use where outright stopping power matters most. Better rear control also takes strain off the front axle, slowing pad and disc wear across the car.

About the Hollow rear brake kit

The Hollow rear kit is a matched disc-and-caliper package engineered specifically for the 323’s rear hubs rather than a generic adaptation. The caliper is a hollow-body forged unit as standard, handling the heavier, sustained clamping loads the original rear hardware was never specified for, while the two-piece floating disc is sized to shed heat across longer, harder use. Discs are offered drilled or slotted at the same price, with two-piece floating construction that lets the friction ring expand cleanly under load. Centre bell upgrades are available in two-tone anodized finishes across five colours, or in titanium. Three pad compounds, Street, Sport and Racing, let you set the kit up for commuting, fast road or circuit work without changing the hardware. Painted caliper colours are included at no extra cost in Red, Yellow, Gold, Black and Anodized Black; a Custom Color matched to any Pantone is available, and premium polished-forged finishes (Titanium, Polished Gold, Polished Silver) and candy finishes (Candy Teal, Candy Blue, Candy Red, Candy Orange) extend the range further. For serious track use a Hollow Racing caliper upgrade adds a 1000C rating, no dust cover and a two-year warranty.
