XYZ Racing Hollow Rear Brake Kit — Scion FR-S (2012-2016)

The ZN6 FR-S leans on brake balance more than outright stopping power. It is a light, momentum-driven car with a near-even weight split, and on a track day the rear discs heat-soak long before the chassis runs out of grip. As the rear loses bite, the car starts to push wide on corner entry and the pedal travel grows.

The XYZ Racing rear brake kit for the Scion FR-S (2012-2016) goes straight at that rear axle. It supplies a matched pair of rear calipers and two-piece floating discs to restore thermal headroom at the back of the car, so the FR-S keeps rotating toward the apex on repeat laps instead of washing into understeer as the standard rear setup fades.

What this brake kit does for your 2012-2016 Scion FR-S

Fit the rear kit and the first thing you feel on the road is a firmer, more consistent pedal once the discs are up to temperature. The two-piece floating discs run hollow internal vanes that shed heat fast and trim rotating mass at each rear corner, which keeps the rear brakes honest deep into a braking zone. Because the kit is offered with Street, Sport and Racing pad compounds, you can match rear bite to how you actually use the car: a quiet, low-dust pad for the commute, Sport for fast road with the odd lap, or a Racing compound that holds its friction when the rotors are glowing. On a trail-braked entry that steadier rear braking helps the FR-S settle and rotate rather than running wide. The kit also lets the hardware sit with the wheel and caliper look you are building toward.

About the rear big brake kit

This is a rear-specific big brake kit built around XYZ Racing’s two-piece floating discs. The floating mount lets the hollow-vane friction ring expand under load without warping its alloy bell, while the internal vane structure opens paths for heat to escape, which is what lets the rear brakes recover between heavy stops. It is sold as a rear-axle package, a matched pair of calipers and discs rather than a pad-and-line tweak, so the upgrade lands exactly where the factory FR-S rear setup gives up first: sustained thermal load. Disc faces come drilled or slotted at the same price, chosen when you order. Pad compound is your call too, Street for road manners, Sport for harder fast-road use, or Racing for circuit sessions. The caliper bodies are hollow-cast as standard, with an optional Hollow Racing upgrade for dedicated track cars that removes the dust cover, is rated to 1000C and carries a two-year warranty. Calipers are finished in Red, Yellow, Gold, Black or Anodized Black at no extra cost, with a custom Pantone match available, so the kit reads as a deliberate part of the build.

Fitment for the Scion FR-S (2012-2016)

This kit is mapped to the rear axle of the Scion FR-S across the full 2012-2016 ZN6 run, the Scion-badged version of the 86 platform. It is a rear-position fitment, so it pairs naturally with a matching front big brake kit if you are upgrading both ends. Confirm your build year against the options above before ordering.
