Hey there, fellow gearheads! If you're looking to give your Subaru a little more pep in its step, let me tell you about these FB lightweight pulley kits. Crafted from tough-as-nails aircraft-grade 6061-T6 aluminum, these pulleys are all about shedding weight on the crankshaft. The result? You’ll feel quicker acceleration that makes your engine feel like it’s ready to party.
Most of these kits are underdriven, which means they spin the accessories a bit slower. This little tweak helps cut down on parasitic losses, letting your engine breathe easier. It’s like swapping in a lighter flywheel—suddenly, your ride feels more responsive and eager to rev. Seriously, it’s a game-changer for your driving experience!
Now, I get it—some folks worry about the downsides of lightweight pulleys and underdriving. But don’t sweat it! We’ve put in the legwork to ensure that the underdrive ratios are spot on, so you won’t have to deal with any negative impacts on your accessories. Plus, we’ve avoided those engine types that can run into harmonic issues with lightweight parts. Our kits are thoroughly tested for fitment and performance, so you can hit the road with confidence, knowing there’s no risk of engine damage now or down the line.
Fitment:
So, if you've got a Subaru Impreza from 1998 to 2002 or a WRX/Forester GT from '99 to '00, this GFB Lightweight Engine Pulley Kit is your ticket to a more spirited drive. Go ahead and give your ride the boost it deserves!

It all started with the passion of John Adrian to create something that other aftermarket parts cannot produce. Most parts he encountered are either of low quality and are made out of inferior materials.
He decided to take matters into his own hands and started designing, testing, and developing parts that would help improve the performance of his vehicle. Using his own car as a personal testbed, he created products that other enthusiasts later noticed, which has become the start of Go Fast Bits.
