XYZ Racing Hollow Rear Brake Kit — Porsche CAYMAN 718 (982) GT4 RS (2022-2026)

The GT4 RS is the hardest-driven car in the 718 range, and it asks more of its rear axle than any road-going Cayman before it. With the mid-engined mass sitting behind the driver and a 4.0-litre flat-six that pulls to 9,000rpm, the rear brakes do real work on corner entry, settling the car as you trail off speed into an apex. The XYZ Racing Hollow Rear Brake Kit for the Porsche Cayman 718 (982) GT4 RS is built for exactly that load.

This is a rear-axle upgrade, fitted as a matched pair, aimed at owners who actually use the car on circuit. The two-piece floating disc trims rotating and unsprung mass at the back, and three pad compound choices – Street, Sport and Racing – let you match bite and heat range to how hard you drive.

What this brake kit does for your 2022-2026 Porsche CAYMAN 718 (982) GT4 RS

On a mid-engined chassis, rear brake stability is what keeps the car composed under heavy braking, and that is where this kit earns its place. Running the Racing pad compound raises the heat ceiling for back-to-back track sessions, so rear bite stays consistent once the discs are up to temperature. The two-piece floating disc reduces rotating mass at the rear hubs, which sharpens response and eases the load passed into the rear suspension, while the floating mount holds the rotor true under sustained heat. For road and mixed use, the Sport and Street compounds keep the pedal predictable and the discs clean at lower temperatures. Caliper finishes in Red, Yellow, Gold, Black or Anodized Black come at no extra cost, with a Pantone Custom Color for £150, so the hardware looks right sitting behind an open wheel.

About the Hollow Rear Brake Kit

The XYZ Racing Hollow Rear Brake Kit is a rear-specific package built around two-piece floating discs that cut weight without giving up swept area. Less rotating mass means faster response and less strain on wheel bearings and rear suspension components. Three pad compounds cover the spread of how a GT4 RS gets used – a Street compound for quieter driving, a Sport compound for fast-road work, and a Racing compound made to hold its friction level under sustained track temperatures. Disc faces are offered drilled or slotted at the same price, with the centre bell available two-tone anodized in five colours or in titanium. Calipers come in five included finishes – Red, Yellow, Gold, Black and Anodized Black – plus a Custom Color option for owners matching a particular scheme, with premium polished-forged and candy finishes alongside. For serious circuit use there is an optional Hollow Racing caliper that drops the dust cover, is rated to 1000C and carries a two-year warranty. It is set up as a direct rear fitment for the GT4 RS rather than a universal kit forced to suit.
