What is the main benefit of a lightweight flywheel?

A lightweight flywheel reduces the engine's rotational mass. This allows the engine to accelerate and decelerate more quickly, leading to improved throttle response and a snappier feel when shifting gears.

What should I consider when installing a lightweight flywheel?

Drivers should be aware that engine braking may feel less significant, and there's a slightly increased chance of stalling if you're not used to the quicker revving. It's often recommended to pair it with a performance clutch kit.

Does this flywheel come with all necessary installation hardware?

This product listing is for the flywheel itself. It is recommended to refer to the manufacturer's installation instructions to determine if any additional hardware or specific tools are required for proper installation.

About this part

Product Details

If you're looking to get a quicker engine response from your Subaru GDB, GRB, or GVB STi, a lightweight flywheel can make a notable difference. This flywheel from Cusco is designed to reduce rotational mass, allowing your engine to rev up and down more freely. It's a popular choice for enthusiasts who want to feel a more direct connection between their throttle input and the engine's RPMs, especially during spirited driving or track use.

Crafted from a solid piece of steel, this flywheel is built to handle the demands of performance driving. By shedding weight compared to the stock flywheel, it directly impacts how quickly your engine can accelerate. This means you'll notice a snappier feel when you shift gears and a more immediate response when you blip the throttle. While it does change the driving feel, many drivers find this improved responsiveness to be a significant upgrade for their STi.

When installing a lightweight flywheel, it's important to be aware that engine braking might feel less pronounced, and the engine may be more prone to stalling if you're not accustomed to the quicker revving. It's often recommended to pair this with a performance clutch kit for the best overall drivetrain enhancement. Always refer to the manufacturer's installation instructions for specific details regarding proper installation and any required hardware.
