What is the main benefit of an aluminum flywheel?

An aluminum flywheel significantly reduces rotational mass compared to a stock steel flywheel. This allows your engine to rev up and down much faster, resulting in improved throttle response and a more lively feel.

Does this flywheel come with new bolts?

This SPEC aluminum flywheel is designed to work with new flywheel bolts, which are recommended for installation. It's best to purchase these separately to ensure proper torque and secure mounting.

What other parts should I consider replacing when installing a new flywheel?

When replacing your flywheel, it's a good opportunity to also replace your clutch disc, pressure plate, and release bearing. Inspecting these components at the same time can save you labor down the road.
