XYZ Racing Hollow Rear Brake Kit — Toyota GR YARIS (GXPA16) (2024-2026)

The GXPA16 GR Yaris leans on its rear axle harder than almost any hot hatch, thanks to a GR-FOUR driveline that can send up to 70 percent of torque rearward in its sportiest mode. The XYZ Racing Hollow Rear Brake Kit for the Toyota GR Yaris (GXPA16) builds the back end up to match, giving the rear discs the thermal headroom to pull their weight on circuit rather than heat-soaking after a handful of hard stops.

Fitted to the 2024-2026 car, this rear big brake kit is aimed at owners who track their GR Yaris or push it hard on demanding roads, where the standard rear rotors warm through quickly under repeated braking into tight corners. It is a left-and-right rear pair, and pad compound choices run from Street through Sport to Racing, so the kit can be specced for a daily that sees occasional lapping or a car that lives at track days.

What this brake kit does for your 2024-2026 Toyota GR Yaris (GXPA16)

Because the GR Yaris carries its mass forward and runs a four-wheel-drive layout, the rear brakes often decide how consistently the car slows from speed. The two-piece floating disc construction trims rotational and unsprung mass, which sharpens pedal response and eases load on the rear hubs. Added thermal capacity keeps rear bite steady through a session, so the car stops square instead of letting the nose wash wide as the rears wilt. Pick the Racing compound and you get higher friction at temperature for heavy, repeated stops; the Street compound holds cold bite and keeps dust down for road use, with the Sport compound bridging the two for fast-road work. Stronger, more progressive rear braking also helps the GR-FOUR chassis rotate cleanly on turn-in.

About the Hollow rear brake kit

The Hollow rear brake kit is XYZ Racing’s lightweight approach to a rear disc and caliper upgrade, named for the hollow-body caliper fitted as standard, cast with internal voids that drop weight at the corner without losing stiffness. It runs vented two-piece floating discs and is a rear-specific kit, so it works with the factory or an upgraded front setup to shift braking effort towards the back axle where an AWD car needs it. Three pad compounds are offered: Street for quiet, low-dust road use, Sport for stronger road stopping and the odd track day, and Racing for circuit work where heat resistance outweighs cold bite. Painted calipers can be finished in Red, Yellow, Gold, Black or Anodized Black at no extra cost, with a Custom Color in any Pantone and premium polished-forged and candy finishes to suit the build. Discs come drilled or slotted at the same price, centre bells can go two-tone anodized or titanium, and a Hollow Racing caliper rated to 1000C is available for the hardest use. The focus throughout is repeatable braking and consistent feel under sustained load.
