If you’re looking to shed some weight off your Subaru BRZ, Scion FR-S, or Toyota GT-86, the GFB Lightweight Pulley Kit is definitely worth considering. These aren’t just any pulleys; they start life as a solid chunk of 6061-T6 aluminum, which is then precision CNC machined. What does that mean for you? It means you’re getting a product that’s crafted to exacting tolerances, ensuring durability and performance. Plus, they come anodized in black, giving them a sleek look while also boosting resistance to wear.
This kit includes three pulleys, and trust me, it’s not just for show. You’re looking at a total weight savings of 2.2 kg, which is pretty impressive compared to swapping out just the crank pulley. But weight alone doesn’t tell the whole story. The real magic happens in the rotating inertia reduction—an astounding 83%. That’s the kind of number that translates directly to performance.
Once you install these pulleys, you’ll notice the difference right away. Your throttle response sharpens, the engine feels eager to rev, and there’s this stronger “urge” that just makes the driving experience more engaging. It’s like giving your car a little boost of enthusiasm.
Fitment:
So, if you’re serious about enhancing your ride, consider the GFB Lightweight Pulley Kit. It’s one of those upgrades that you can really feel, making your driving experience that much more enjoyable.

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.
