XYZ Racing Hollow Rear Brake Kit — Audi R8 (2007-2015)

The Type 42 R8 carries its V8 or V10 behind the cabin, and that rearward mass bias means the back axle does more braking work than it would on a front-engined GT. The XYZ Racing Hollow Rear Brake Kit for the Audi R8 targets exactly that load, using a lighter two-piece floating disc at the rear where heat stacks up during repeated hard stops from three figures.

This is a rear-axle setup for owners who use their R8 on fast road and circuit rather than just the supermarket run. It pairs reduced rotating mass with a choice of pad compound, so the rear brakes can be set to match how the car is actually driven.

What this brake kit does for your 2007-2015 Audi R8

Take rotating and unsprung mass out of the rear and the R8’s dampers have less inertia to control, so the back axle settles quicker over kerbs and mid-corner ridges. The hollow-vane disc design pulls heat away from the friction face, which keeps rear braking force consistent when you are linking stops on a track day rather than scrubbing off speed once on the motorway. The Racing pad compound gives sustained circuit bite, the Sport compound suits fast road and the occasional track day, and the Street compound keeps cold-morning road manners civil and dust low. Braided lines hold a firm pedal as temperatures climb. Behind the R8’s open-spoke wheels the forged caliper is on display, and the kit comes in Red, Yellow, Gold, Black or Anodized Black at no extra cost, with a custom Pantone finish available.

About the Hollow Rear Brake Kit

XYZ Racing builds this as a dedicated rear-axle kit for the R8, centred on a two-piece floating disc that trims rotating mass without surrendering thermal capacity. The forged caliper is hollow-bodied as standard, and the disc’s internal vanes add surface area for venting heat, so the rotor recovers temperature between braking events instead of soaking and fading. Three pad compounds are offered: Street for quiet road use, Sport for a firmer fast-road bite and light track work, and Racing for sustained circuit sessions, letting you tune the rear axle’s character to the car. The caliper comes in five included finishes, Red, Yellow, Gold, Black and Anodized Black, with a custom Pantone option for a specific build. Discs can be drilled or slotted at the same price, and the centre bell upgrades to two-tone anodized in five colours or titanium. Because this is rear-specific, it is sized to balance against the front brakes rather than overpower them and unsettle the mid-engined R8 under trail braking.

Fitment for the Audi R8 (2007-2015)

This kit covers the first-generation Audi R8 (2007-2015), the Type 42 chassis, and bolts to the rear axle. It is a rear-only kit, a pair of rear calipers and discs, so match it with a suitable front setup if you are upgrading both ends. Confirm your exact model year before you order.
