GFB lightweight BRZ/86/FR-S pulley kit (part number 2016) is made from anodized aircraft-grade billet 6061-T6 aluminium and offers sharper throttle response and faster acceleration. Kit includes: crank, alternator and water pump pulleys (original factory belt is used with this kit).
GFB pulley kits are designed to improve acceleration by reducing the rotational mass (inertia) of the belt train. The effect is similar to a lighter flywheel, and the engine feels more lively and willing to rev.
fit for TOYOTA 86 (ZN6) GT-GTS 12-on
