The ACT 600521 Flywheel Prolite Pressure Clutch Kit is an upgrade for those seeking improved power transfer, durability, and a more engaging driving experience. This clutch system includes a lightweight flywheel, a pressure plate, and a performance clutch disc, all designed to handle the increased power and torque produced by modified engines.

The Flywheel Prolite is a weight-reduced, nodular-iron flywheel that provides a substantial reduction in rotating mass compared to the stock flywheel.

Furthermore, the Flywheel Prolite's surface finish is engineered for superior friction coefficient, ensuring a positive engagement between the clutch disc and the flywheel.

The Performance Clutch Disc in this kit features a high-carbon, Kevlar-reinforced friction material that delivers excellent grip and durability. The disc's spline design is engineered to provide a secure fit and positive engagement with the pressure plate. The clutch disc's friction material is also designed to provide consistent engagement, reducing slippage and ensuring optimal power transfer.

The Pressure Plate in this kit is designed to handle the increased power and torque produced by performance upgrades. Its robust design ensures durability and reliability, while its engineered spring rate provides optimal clamping force for the clutch disc. Additionally, the pressure plate's diaphragm design helps to minimize pedal effort and provides a smoother, more progressive feel when engaging the clutch.

Installing the ACT 600521 Flywheel Prolite Pressure Clutch Kit is a straightforward process and can be done with basic hand tools. A detailed installation guide is provided with the kit to ensure a successful installation.

In summary, the ACT 600521 Flywheel Prolite Pressure Clutch Kit is an excellent upgrade for Mazda Mazdaspeed3 owners seeking improved power transfer, durability, and a more engaging driving experience. With its lightweight flywheel, high-performance clutch disc, and robust pressure plate, this kit is designed to handle the power produced by performance upgrades while providing smoother power delivery and quicker engine response.
