XYZ Racing Hollow Rear Brake Kit — Subaru IMPREZA GC8 (WRX) φ 265/ φ 171 (1997-2000)

The GC8 Impreza WRX leans on its rear axle harder than most owners give it credit for. The symmetrical all-wheel-drive layout keeps the back wheels loaded through long, committed corners, and the factory rear discs run short of thermal headroom on a hot track session or a quick B-road. This XYZ Racing Hollow Rear Brake Kit fits a 265mm two-piece floating rotor behind each rear wheel of the 1997-2000 car, giving the back of the chassis the heat capacity to match how the EJ20 turbo platform actually gets driven.

It is a rear-axle upgrade aimed at owners who already understand that brake balance, not just front-end bite, is what keeps a quick Impreza composed under repeat heavy braking. Supplied as a matched pair of rear calipers and discs for the left and right corners, it stops the rear from being the first thing to go away when the pace climbs.

What this brake kit does for your 1997-2000 Subaru Impreza GC8 (WRX)

On the GC8 the gain shows up where the standard rear brakes struggle: trail-braking into a corner with the AWD system still shuffling torque rearward. The larger 265mm rotor adds swept area and thermal mass, so the rear pedal holds its bite through a sequence of stops instead of going soft. The two-piece floating disc lets the friction ring run cooler and flatter, while the lighter rotor trims rotational and unsprung weight, sharpening how quickly the rear wheels respond to inputs and helping the back end settle. With Street, Sport and Racing pad compounds offered, you can match the rear bias to road use, fast-road work or stage and circuit duty.

About the Hollow rear brake kit

The kit is built around a two-piece floating rear rotor measured at φ 265 outer and φ 171 inner, a construction that lets the friction ring expand freely against the alloy bell while keeping the heat capacity a bigger rotor brings. Cutting weight from the rotor reduces the load the rear hubs and dampers have to control, so the rear of the car reacts faster over kerbs and crests. Disc faces are offered drilled or slotted at the same price, and the centre bell upgrades to a two-tone anodized finish in five colours or to titanium, both selectable at checkout. Three pad compounds let you set the rear brake character to suit the use case, from daily driving to sustained track laps. The hollow-cast caliper ships painted in Red, Yellow, Gold, Black or Anodized Black at no extra cost, with a Custom Color in any Pantone for £150, plus premium polished-forged Titanium, Polished Gold and Polished Silver finishes and candy Teal, Blue, Red and Orange options. A Hollow Racing caliper upgrade, rated to 1000C with a two-year warranty and no dust cover, is there for serious track use. As a rear-specific kit it is designed to work alongside a front big brake setup, keeping front-to-rear balance honest as overall braking capacity goes up.
