• 2024 GR86 fitment excludes vehicles equipped with the factory Performance Brake Package (larger Brembo-style brakes).
• Rear axle only.

Product Description

The PowerStop K5883 is a rear Z23 Evolution Sport brake upgrade covering the Toyota 86/GR86, Subaru BRZ, Scion FR-S, and the 3.6R engine variants of the Subaru Legacy and Outback. It pairs carbon-fiber ceramic pads with drilled and slotted rotors for daily drivers who want a noticeable step up in braking feel and dust control over stock rear brakes.

The Z23 pad compound improves stopping performance over a typical replacement pad while staying low-dust - validated through independent testing at roughly 30% less dust than OE. Multi-layer rubberized shims keep the kit quiet in daily use, and the drilled-and-slotted, zinc-plated rotors add cooling and long-term rust resistance.

Because this kit spans two very different vehicle families - sporty rear-drive coupes (86/BRZ/FR-S/GR86) and Subaru's larger 3.6R sedans/wagons - fitment depends heavily on caliper type and rotor configuration within each model year. Confirming exact trim and brake hardware before ordering will avoid the most common mismatch on this listing.
