Go Fast Bits 2010 Lightweight Pulley Kit

If you’re looking to enhance your Subaru’s performance, the Go Fast Bits 2010 lightweight pulley kit might just be what you need. Crafted from aircraft-grade 6061-T6 aluminum, this pulley kit is designed to significantly reduce weight on the crankshaft, allowing for quicker acceleration. Many users have noted how their vehicles feel more responsive and eager to rev after installation, making driving a more enjoyable experience.

One of the standout features of this kit is its underdriven design. By slightly slowing down the accessories, it minimizes parasitic losses, which can often bog down engine performance. This reduction in rotational mass translates to a livelier engine, similar to the effects of a lighter flywheel. Customers have shared feedback such as, “I noticed a real difference in how my WRX accelerates; it feels much more agile now!”

We understand that some car enthusiasts might have concerns regarding lightweight pulleys and their potential drawbacks. However, the Go Fast Bits team has ensured that the underdrive ratios are optimized to prevent any adverse effects on accessory performance. Extensive testing has shown that this kit does not cause any long-term damage to the engine, alleviating worries about harmonic issues that can arise with other lightweight pulleys.

Technical Specifications:

  • Material: Aircraft-grade 6061-T6 aluminum
  • Weight Reduction: Significant decrease in crankshaft weight
  • Underdrive Design: Optimized ratios to minimize parasitic losses

Fitment:

  • Subaru WRX | STI 04-10

Overall, the Go Fast Bits 2010 lightweight pulley kit offers a practical and effective way to boost your Subaru's performance without compromising reliability. Many users have found it to be a worthwhile upgrade, commenting on the noticeable difference it makes in their driving experience. If you’re ready to take your vehicle to the next level, this is definitely a product to consider.

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.

Lifetime Warranty
We live in a throw-away society, conditioned by cheap products and frequently released new models to expect eventual failure and discard something when it stops working or is superseded. However, pride in workmanship and our commitment to quality means that when we put our name to something, we are also staking our reputation on it.

That’s why we back our products with the best Warranty in the business! You should expect a lifetime of use from a well-engineered product, so if your GFB product fails as a result of defective materials or faulty workmanship whilst you remain the original owner, we will repair or replace it.

If the fault occurred as a result of usage outside of the terms of the warranty, or you are not the original owner, fear not, we can still help you. You should never need to throw a GFB product away, as spare parts are available and won’t cost the earth.
