XYZ Racing Hollow Rear Brake Kit — Porsche 996 GTR (2002-2005)

The 996-generation 911 carries roughly two-thirds of its mass over the rear axle, which means the back brakes on a Porsche 996 GTR do far more of the work than they would on any front-engined coupe. Get the rear end right and the whole car settles under braking; get it wrong and the tail goes light at exactly the moment you need it planted. The XYZ Racing Hollow Rear Brake Kit for the 2002-2005 Porsche 996 GTR tackles that directly, adding rear stopping capacity built to survive repeated heavy use.

This is a rear-axle upgrade for owners who drive the car the way it was meant to be driven: hard road work and track sessions where road pads start to wilt. It fits as a matched pair of rear calipers and discs, pairing a larger, more thermally stable setup with a choice of pad compound, so the rear keeps biting on the fourth lap rather than sinking into a long, soft pedal.

What this brake kit does for your 2002-2005 Porsche 996 GTR

On a rear-heavy 911, fade at the back shows up as a spongy pedal and a car that wants to run wide on corner entry. More rear thermal capacity holds pedal travel consistent as the discs heat, so trail-braking into a slow corner stays predictable. The three pad compounds let you match the axle to the job: Street for road, Sport for fast-road and occasional track, Racing for sustained circuit work. Stronger, more stable rear bite also helps the car rotate cleanly under braking, sharpening turn-in without provoking the tail. The caliper finishes – Red, Yellow, Gold, Black or Anodized Black at no extra cost, with a Pantone Custom Color for £150 – let the kit sit behind the wheel exactly how you want it read.

About the Hollow rear brake kit

The Hollow rear brake kit is XYZ Racing’s big brake package for the rear axle, sized up over the standard 996 GTR rear arrangement to add disc area and heat headroom. It pairs the XYZ Racing caliper with a two-piece floating disc, the rotor mounted on an alloy bell so it can move under heat rather than cone or warp. It is a complete rear-axle solution rather than a pad-and-fluid refresh, aimed at owners chasing repeatable braking under load. Three pad compounds are offered – Street, Sport and Racing – so the same hardware suits a road car, a fast-road build or a dedicated circuit setup depending on how hard the car is worked. Disc faces come drilled or slotted at the same price, and the centre bell can be specified two-tone anodized in five colours or in titanium. The caliper comes in five included finishes: Red, Yellow, Gold, Black and Anodized Black, with a Custom Color option and premium polished-forged and candy finishes available. For circuit-focused builds, the optional Hollow Racing caliper drops the dust cover, is rated to 1000C and carries a two-year warranty. Because it targets the rear of a rear-engined platform, the emphasis is on consistent bite and resistance to heat soak, which on a 911 governs braking stability as much as raw clamping force does.

Fitment for the Porsche 996 GTR (2002-2005)

This is the rear brake kit specified for the Porsche 996 GTR built between 2002 and 2005. It is a rear-axle kit, so it works alongside your existing or upgraded front brakes rather than replacing them. Confirm your build year falls inside the 2002-2005 window before configuring, as the rear hardware is matched to this generation of the 996 platform.
