4-Piston Brake Caliper Kit - 340mm Rotor for 2013+ Subaru BRZ & Toyota GR86 by GrimmSpeed
The stock single-piston caliper found on most Subaru platforms gets the job done — but it wasn’t designed for the kind of aggressive driving, tracking, or build evolution most GrimmSpeed drivers pursue. That’s where Grimmspeeds 4-Piston Brake Caliper Kit comes in.
Purpose-built for Subaru performance, this fixed caliper setup brings balanced stopping power, improved heat management, and consistent pedal feel to your favorite chassis. Designed in-house and tested under real-world conditions, the system offers a true performance solution — with no need to chase down used Brembos or deal with custom brackets.
