OVERVIEW
Combine flagship 6-piston pedal control with versatile wheel fitment using the Project Mu 6POT FS6 Forged Front Caliper Kit for 2013+ GR86 / BRZ / 86 / FR-S (ZN6/ZC6/ZN8/ZD8). Engineered as Project Mu's ultimate response-focused front system, the FS6 features a forged aluminum body housing staggered 30mm, 36mm, and 38mm pistons. This progressive piston configuration balances clamp pressure across the pad face to eliminate pad taper and optimize initial bite modulation. Paired with heavy-duty 345mm x 32mm 2-piece straight 8-slit floating rotors, this 345mm variant offers race-proven thermal capacity while expanding compatibility to select high-performance 17-inch track wheels.

FEATURES
- Flagship Forged 6-Piston Architecture: High-rigidity forged aluminum alloy caliper body provides exceptional structural stability and pedal feel under extreme hydraulic force.
- Staggered Piston Diameters: 30mm, 36mm, and 38mm pistons equalize pressure distribution across the pad length, preventing uneven wear and pad taper.
- 345mm x 32mm 2-Piece Floating Rotors: Billet aluminum hat and extra-thick 32mm floating rotor ring provide excellent thermal resistance while fitting select 17-inch wheels.
- Straight 8-Slit Rotor Face: Degasses pad friction material, vents out boundary gases, and refreshes the pad friction layer under continuous heavy track braking.
- Dual Hydraulic Seal Protection: Dedicated outer dust boots shield inner fluid seals from brake dust, grit, and track debris.
