XYZ Racing Hollow Rear Brake Kit — Infiniti FX35 S51 (2009-2012)

The FX35 S51 carries close to two tonnes on its front-midship platform, and the rear axle does more braking work than the car’s luxury-crossover image suggests, especially on an AWD chassis that can shuffle drive rearward through a corner. The XYZ Racing Hollow Rear Brake Kit for the Infiniti FX35 S51 (2009-2012) replaces the factory rear setup with hollow-vane rotors built to shed heat faster and hold a firmer pedal once standard discs start to fade.

This is a rear-axle kit, sized and configured for repeat stops rather than a single hard one. Match the pad compound to how you actually drive the car, finish the calipers to suit the build, and you get rear braking that stays consistent on a long descent or a quick B-road instead of going soft halfway down.

What this brake kit does for your 2009-2012 Infiniti FX35 S51

On a vehicle this heavy, rear brake performance comes down mostly to heat. The hollow-vane rotor moves heat away from the friction surface quicker than a solid equivalent, which keeps rear pedal feel firm when you brake hard from speed time and again. That matters on the FX35 because the VQ35HR will carry the car to motorway pace with no effort, and the rear axle has to help wash that speed off without cooking. Three pad compounds let you set bite and temperature range to your use: Street for quiet, low-dust road familiarity, Sport for sharper everyday response with more heat range, and Racing for sustained high-temperature work. The result is shorter, more predictable stops and a balance that no longer leans entirely on the front discs.

About the Hollow Rear Brake Kit

The Hollow Rear Brake Kit is XYZ Racing’s rear big brake package, named for the hollow-vane rotors at its core. Hollowing the disc cuts rotating mass at the rear while opening internal paths for air, so the rotor warms and cools more evenly than a heavier solid casting. The two-piece floating rotors run cooler still, and the caliper body is hollow as standard. It ships with a choice of three pad compounds, Street, Sport and Racing, so the same hardware suits a relaxed road car, a fast-road FX35, or a heavy crossover being worked hard on track days. Discs come drilled or slotted at the same price. Calipers come in Red, Yellow, Gold, Black or Anodized Black at no extra cost, with premium polished-forged Titanium, Polished Gold and Polished Silver, candy Teal, Blue, Red and Orange, or any Pantone shade as a custom colour to match the rest of the build. As a rear-specific pair of discs and calipers it is designed to work alongside the front brakes, rebalancing how the FX35 sheds speed and taking load off the front discs for a more even, more repeatable bite under hard use.
