Ultimate Stage 3 Clutch Kit for Subaru WRX STI

The Stage 3 Clutch Kit (1MS) by Action Clutch is engineered for the Subaru WRX STI 2004-2021, 2.5L DOHC (EJ257) Turbo AWD. This kit is a comprehensive solution for vehicles seeking peak performance and extreme durability, designed to handle the most challenging conditions. The core of this kit is the heavy-duty single diaphragm pressure plate, reinforced drive straps, and a Sprung MIBA Ceramic disc, available in 4 or 6 puck configurations. This combination ensures that your vehicle can maintain its power and control, even under heavy use.

Key Features and Specifications

The Stage 3 (1MS) Clutch Kit boasts a torque holding capacity of 594 ft/lbs, making it suitable for heavy-duty street use and occasional drag, road, or drift racing. It includes a Sprung MIBA Ceramic 6 Puck Disc, a Single Diaphragm HD Pressure Plate, a Pilot Bearing/Bushing (when applicable), a Clutch Alignment Tool, and a Conventional Release Bearing. This kit is designed for low/mild horsepower vehicles, providing quicker engagement and a more responsive driving experience. However, it's important to note that the Sprung MIBA Ceramic clutch kit may introduce some clutch chatter, which will minimize after proper break-in.

Applications and Benefits

The Stage 3 Clutch Kit is perfect for drivers who want to take their Subaru WRX STI to the next level. It offers maximum control and power with minimal compromise on reliability. This kit is ideal for those who engage in heavy-duty street use and occasional racing, providing the necessary holding capacity and durability. With proper break-in, which includes 500 street miles with RPMs under 4500 and no more than half-throttle, the kit ensures longevity and optimal performance. The Action Clutch kit, with its SFI Spec 1.1 certification, is a testament to its safety and quality, making it a must-have for any Subaru WRX STI enthusiast.
