XYZ Racing Hollow Rear Brake Kit — Toyota GR86 (2021-2026)

The GR86 carries very little mass over its rear axle, and under hard braking that load shifts further forward still. The back of the car goes light at exactly the moment you want the rears doing useful work. The XYZ Racing Hollow Rear Brake Kit for the Toyota GR86 (2021-2026) targets that behaviour, handing the rear axle more thermal headroom and steadier bite so the balance you set on corner entry stays where you put it.

It is a kit for owners who drive the GR86 the way it was built to be driven: trail-braking into apexes, stringing corners together across a track-day afternoon, leaning on the chassis rather than outright power. The two-piece floating disc design trims rotating mass at each rear corner, and three pad compounds, Street, Sport and Racing, let you match the rear to how hard you actually drive.

What this brake kit does for your 2021-2026 Toyota GR86

The first thing you feel on the GR86 is consistency: a rear end that resists the fade which creeps in over a hot session of lapping, so the pedal sits where you expect it on the tenth lap as much as the first. The Racing compound bites harder for circuit use, the Sport compound widens the heat range for fast-road work, and the Street compound stays quiet and clean for the commute. Lighter two-piece rotors cut rotating and unsprung mass at the rear, sharpening how quickly the car settles when you release the brake and turn in. With painted caliper finishes in Red, Yellow, Gold, Black or Anodized Black and a wider range of premium options, the kit reads as intent behind the wheels rather than decoration.

About the Hollow Rear Brake Kit

The Hollow Rear Brake Kit is XYZ Racing’s rear-axle upgrade for the GR86, running a hollow-body caliper as standard, cast with internal voids to cut weight at the corner while keeping the housing rigid. It is built around two-piece floating rotors that shed weight without surrendering swept area or heat capacity, with material removed where it does no braking work, so each rear corner spins less mass while still managing temperature across repeated stops. The caliper clamps a larger, better-ventilated disc than the standard rear arrangement, and that is what buys the extra fade resistance. Pad choice runs from a Street compound for quiet, low-dust road use, through a Sport compound for fast road and light track, to a full Racing compound for circuit work, so the rear can be specified to sit in balance with whatever front setup the car runs. Discs are drilled or slotted at the same price, centre bells can go two-tone anodized or titanium, and a Custom Color in any Pantone plus polished-forged and candy finishes let the look suit the build. A Hollow Racing caliper rated to 1000C is offered for serious track cars.
