XYZ Racing Hollow Rear Brake Kit — Porsche 996 GT2 (1999-2004)

The 996 GT2 carries its twin-turbo flat-six behind the rear axle and drives the rear wheels alone, so the back brakes on Porsche’s hardest 996 shoulder a thermal load that front-heavy cars never ask of theirs. Heat soak at the rear is the limiting factor on a long downhill or a sustained braking zone, and a tired standard setup shows it first as a long pedal and then as fade. This XYZ Racing rear big brake kit for the Porsche 996 GT2 (1999-2004) is aimed squarely at that problem, giving the rear axle a pair of high-capacity discs and calipers built to keep working when the original hardware has run out of margin.

The kit fits the rear axle as a matched pair, left and right, with hollow-bodied calipers clamping two-piece floating discs. The floating disc lets the rotor expand and shrink under heat without coning or feeding stress into the alloy bell, while the vented, hollow-vane rotor opens internal paths for air to move heat off the friction face. On a car already weighted rearward, taking grams out behind the axle line is worth more than the same removed up front, and the result is a rear axle that recovers between stops rather than stewing in its own heat.

What this big brake kit does for your 1999-2004 Porsche 996 GT2

The first thing you feel after fitting is a firmer, more consistent pedal once the car is up to temperature: the rear holds its bite where the original kit would have started going soft. Lighter discs cut rotating and unsprung mass at the rear corners, so the back axle settles faster over kerbs and broken surfaces while you are hard on the brakes. With pad compounds spanning Street, Sport and Racing, you set the rear’s character to suit how you use the GT2: Street for quiet, low-dust road miles, Sport for the bite and heat range of fast road with the odd track session, and Racing for circuit days where rear stability under trail braking decides the corner. Because the GT2 has no all-wheel-drive system to mask a nervous tail, predictable, repeatable rear braking is not a nicety here, it is what keeps the car pointing where you aimed it.

About the Hollow Rear Brake Kit

The kit is built around two-piece floating discs that reduce mass without surrendering swept area, paired with calipers finished in your choice of Red, Yellow, Gold, Black or Anodized Black at no extra cost. The disc face is offered drilled or slotted at the same price, and the centre bell can be upgraded to a two-tone anodized finish in five colours or to titanium, all selected when you order. For owners who want a Pantone-matched look, Custom Color is available for an additional £150. Three pad compounds cover the spread of how a GT2 gets used, from a road-friendly Street pad through Sport to a full Racing mix, so one set of hardware suits a road-biased car or a weekend track tool. For serious circuit use there is an optional Hollow Racing caliper upgrade: no dust cover, rated to 1000C, with a two-year warranty. This is a rear-axle kit, sized to complement the front rather than overpower it, keeping the GT2’s brake balance honest as you raise the pace.

Fitment for the Porsche 996 GT2 (1999-2004)

This kit is specified for the rear axle of the Porsche 996 GT2 across the 1999-2004 build span. It is matched to the GT2 specifically rather than the wider 996 range, so the rear-biased weight distribution and the GT2’s standalone rear-drive layout are accounted for in the application. Confirm your chassis and model year against the options above before ordering.
