GFB 94-98 Subaru WRX Light-Weight Engine Pulley (Crank/Alternator/Power Steering Pulleys/Belts inc)

Go Fast Bits

Size Guide
It might be hard to imagine how reducing the mass of a pulley makes a car go faster, but accelerating a heavy factory pulley from say 3000-7000 RPM in a second or two saps a measurable amount of torque. GFB Lightweight Pulleys reduce inertia by up to 85 percent, so most of the torque that used to accelerate the pulley can now be applied to the wheels.
