XYZ Racing Hollow Rear Brake Kit — Porsche 997 C2 (2005-2011)

The 997 C2 carries its flat-six behind the rear axle, and that rearward mass changes how the car stops. Where a front-engined coupe unloads its back tyres the instant you touch the pedal, the 911 keeps weight planted over the rear wheels, so the rear brakes are doing far more than holding station. This XYZ Racing Hollow Rear Brake Kit for the Porsche 997 C2 rebuilds that end of the car with a larger, lighter package built to take repeat heat.

For fast-road and circuit use, the priority at the back of a 997 is consistency once the discs are hot, not raw initial bite. This kit fits the rear axle as a matched pair, pairing a two-piece floating disc with a fixed caliper and a choice of pad compounds, so you can match the rear axle to how hard you actually drive.

What this big brake kit does for your 2005-2011 Porsche 997 C2

On the road you notice the rear kit less as savage stopping power and more as composure: the back axle settles earlier on turn-in because the discs are not already fading from the last corner. The lightened disc strips rotational mass from each rear corner, which sharpens how quickly the 997 reacts to steering and ride inputs. Step up to the Racing pad compound and the kit shrugs off the heat soak that turns standard rear brakes greasy after three or four hard laps. Street and Sport compounds keep the pedal civil and the dust manageable for a car that still sees weekend road miles. Across all three, the bigger swept area gives you a firmer, more progressive pedal you can lean on without second-guessing the rear.

About the Hollow Rear Brake Kit

The Hollow Rear Brake Kit is built around a two-piece floating disc with hollow internal vanes, machined to cut weight while keeping thermal mass where it matters. Less rotating weight at each rear hub means the wheel changes speed and direction more readily, and a cooler-running disc holds its friction coefficient deeper into a session. The fixed caliper clamps more evenly than a sliding arrangement, which firms up pedal feel and keeps pad wear consistent across the face. Pad compound is a genuine choice rather than a single fitment: Street for road manners, Sport for harder fast-road work, and Racing for circuit heat. Disc faces are offered drilled or slotted at the same price, with the centre bell available in a two-tone anodized finish across five colours or in titanium. Calipers are finished in your pick of Red, Yellow, Gold, Black or Anodized Black at no extra cost, with a Pantone Custom Color for £150, so the kit can hide behind the wheels or sit as a deliberate detail. For sustained track use, an optional Hollow Racing caliper drops the dust cover, is rated to 1000C and carries a two-year warranty. It is a rear-axle kit designed to balance a matching front upgrade, or to firm up a 997 whose front brakes are already sorted.
