What is the primary benefit of using an aluminum flywheel?

An aluminum flywheel is significantly lighter than a stock steel flywheel. This reduced rotational mass allows the engine to rev up and down more quickly, leading to improved throttle response and a sportier feel.

What type of clutch is this flywheel designed to be used with?

This SPEC aluminum flywheel (SP90A-2) is specifically designed for use with a billet single mass flywheel setup. It is not intended for use with a dual-mass flywheel.

Does this flywheel come with any hardware or alignment tools?

This product listing is for the SPEC aluminum flywheel only. Any necessary installation hardware, such as flywheel bolts or clutch alignment tools, would typically need to be purchased separately.

This listing is for a SPEC aluminum flywheel, part number SP90A-2. This flywheel is specifically designed for 2005-2008 Porsche 997.1 S and C4S models equipped with the 3.8L engine. It is intended for use with a billet single mass flywheel setup, offering a lighter alternative to the stock component.

Crafted from high-grade aluminum, this flywheel is significantly lighter than its factory counterpart. This reduction in rotational mass allows the engine to rev more freely and quickly, leading to improved throttle response and a more engaging driving experience. The aluminum construction also helps to dissipate heat more effectively than heavier steel flywheels. This part is designed to be a direct replacement for the original flywheel, ensuring a proper fit when installed with the compatible billet single mass flywheel.

When considering a flywheel upgrade, especially for performance-oriented vehicles like the Porsche 997.1 S and C4S, the choice of material and weight plays a crucial role in how the car feels and performs. This SPEC aluminum flywheel offers a noticeable change in acceleration characteristics due to its reduced mass. Ensure you are using the specified billet single mass flywheel for optimal performance and compatibility with this SPEC aluminum flywheel.
