What is the main benefit of a Stage 3 clutch over a stock clutch?

A Stage 3 clutch, like this SPEC kit, is designed to handle significantly more torque than a factory clutch. This makes it ideal for vehicles with engine modifications that increase power output or for drivers who engage in demanding driving conditions.

Does this clutch kit include a new flywheel?

This SPEC Stage 3 Clutch Kit includes the clutch disc, pressure plate, and release bearing. It is recommended to inspect your existing flywheel for wear and resurface or replace it as needed during installation.

How does the sprung clutch disc affect driving feel?

The sprung clutch disc in this kit helps to dampen vibrations and shock loads. This generally results in a smoother engagement and a more comfortable driving experience compared to unsprung, solid-hub clutch discs, especially in daily driving situations.
