Subaru WRX Pulley Kit - Go Fast Bits (GFB) Lightweight Engine Pulley Kit for 1999-2000 models. This 3-piece underdrive set trims rotating mass to sharpen throttle response and help the engine rev more freely.

CNC machined from a single billet of 6061-T6 aluminum, this kit delivers a straightforward bolt-on improvement with no supporting mods or tuning required. By cutting pulley inertia by up to 85% (application dependent) and underdriving the accessories to reduce parasitic load, more of the engine's torque can reach the wheels while accessory performance is maintained. Fits Subaru WRX/STI MY99-00.
