Competition Clutch 04-20 Subaru STi Stage 4 - 6 Pad Ceramic Clutch Kit

The six-puck sprung disc in this Competition Clutch Stage 4 kit features ceramic buttons, a design choice that helps it engage firmly and quickly, which is crucial when you're dealing with higher horsepower applications. This kit is built for the Strip Series, meaning it's intended for serious performance use where rapid engagement and significant torque handling are priorities.

This Stage 4 kit is designed to handle up to a 250% increase in torque capacity over stock, making it a solid option if you've modified your Subaru Impreza or WRX STI's engine for more power. It includes a performance pressure plate, the high-torque sprung disc with ceramic buttons, a throw-out bearing, a pilot bearing, and an alignment tool, so you have the essential components needed for the swap. The sprung design of the disc helps absorb some of the shock during engagement, which can make it a bit more manageable for daily driving compared to a rigid hub disc, though it's still a performance-oriented setup.

When installing a clutch kit like this, it's always a good idea to have a factory service manual handy for your specific Subaru model. Pay close attention to the alignment tool's use to ensure the clutch disc is perfectly centered before you attempt to bolt up the pressure plate. This helps prevent clutch chatter and ensures smooth operation after installation.
