GiroDisc GR86 / BRZ Slotted Rotors - Front (Brembo)

Overview

These GiroDisc 2-piece rotors are a direct replacement for Toyota 86 and Subaru BRZ models equipped with a big brake kit (BBK). Designed to reduce unsprung weight and rotating mass, each rotor weighs just 16.6 lbs, improving front-end response, braking performance, and overall vehicle dynamics.

Engineered for both street and track use, these fully floating rotors combine advanced metallurgy, efficient cooling design, and serviceable construction. The reusable aluminum hat allows you to replace only the friction rings when worn, reducing long-term ownership costs while maintaining peak performance.

Manufactured entirely in-house in Bellingham, Washington using domestically sourced materials, GiroDisc ensures precision, durability, and race-ready reliability.
