XYZ Racing Hollow Rear Brake Kit — Porsche 997 C2S (2005-2011)

The 997 C2S carries the bulk of its mass over the rear axle, and that rearward bias is exactly why the back brakes earn their keep on a 911 in a way they never would on a front-engined car. Under hard braking the loaded rear contributes real stopping force, and the standard discs heat-soak quickly once you start stringing corners together. The XYZ Racing Hollow Rear Brake Kit for the Porsche 997 C2S targets that weakness directly, swapping the factory rear setup for a lighter, more thermally stable assembly built to take repeated heavy stops.

This is the rear half of the braking equation for owners who track their 997 or lean on it hard on a fast road. Fitted as a matched pair to the rear axle, with two-piece floating discs that trim rotating mass and a choice of three pad compounds, it is aimed at drivers who want the rear axle to keep biting after the brakes are good and hot.

What this brake kit does for your 2005-2011 Porsche 997 C2S

After fitting, the first thing you feel is consistency: the rear pedal holds its bite through successive stops instead of fading as the discs cook. The two-piece floating disc reduces unsprung and rotating weight at each rear corner, which sharpens turn-in response and eases the load on the 997’s rear suspension. The floating mount also lets the rotor grow and shrink under heat without coning, holding its shape lap after lap. Matching the rear to a serious front setup keeps brake balance honest, so the tail stays settled under trail-braking rather than feeling nervous. Pick the Racing compound for circuit days, the Sport compound for spirited road use, or the Street compound for a quieter daily setup – the hardware is the same, the feel is yours to specify.

About the Hollow rear brake kit

The Hollow rear brake kit replaces the 997 C2S’s standard rear discs and calipers with an uprated assembly designed around heat management and weight. The two-piece floating disc removes material where it does the least work, dropping rotating mass without sacrificing the swept area you need to dump heat on a heavy car. Pad compound is a build choice: Street, Sport, or Racing, each tuned to a different use case from road to repeat track sessions. Disc faces are 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. Calipers come finished in Red, Yellow, Gold, Black, or Anodized Black at no extra cost, with a Pantone Custom Color for £150, so the kit looks the part behind an open wheel. Premium polished-forged and candy finishes are available for owners chasing a particular look. As a rear-specific kit, it is engineered to partner a front big brake upgrade and restore proper front-to-rear balance on a rear-heavy 911, with an optional Hollow Racing caliper – no dust cover, rated to 1000C, two-year warranty – for hard circuit duty.
