OVERVIEW
Achieve the ideal balance of heat capacity, piston modulation, and 18-inch wheel fitment with the Project Mu 6POT FS6 Forged Front Caliper Kit for 2013+ GR86 / BRZ / 86 / FR-S (ZN6/ZC6/ZN8/ZD8). Designed as Project Mu's high-performance mid-size 6-piston architecture, the FS6 caliper features a forged aluminum housing equipped with staggered 30mm, 36mm, and 38mm pistons. This staggered layout ensures uniform pressure across the entire brake pad length to mitigate pad taper and optimize pedal feel. Paired with 355mm x 32mm 2-piece straight 8-slit floating rotors, this kit provides extensive thermal capacity for high-speed track sessions and aggressive time attack driving.

FEATURES
- Flagship Forged 6-Piston Architecture: Forged aluminum construction offers maximum structural rigidity, ensuring consistent pedal resistance under elevated temperatures.
- Staggered Piston Sizing: Staggered 30mm, 36mm, and 38mm pistons prevent pad deformation, maintaining uniform contact across the friction surface.
- 355mm x 32mm 2-Piece Floating Rotors: Billet aluminum center hats paired with floating 32mm thick rotor rings increase thermal capacity and dissipate heat quickly.
- Straight 8-Slit Rotor Face: Cleans pad contact surface, releases gas buildup, and boosts friction bite during repeated high-speed braking.
- Dual Hydraulic Seals: Weather-resistant dust seals protect internal pressure seals from high-temperature brake dust and track contamination.
