The Action Clutch Stage 6 (2MD) Clutch Kit, part number ACR-1821, is engineered for high-performance 2015-2018 Subaru WRX models equipped with the 2.0L DOHC FA20DIT turbocharged engine and all-wheel drive. Designed for race applications, heavy track use, and limited street driving, this kit delivers a substantial increase in holding capacity over the factory clutch while maintaining the durability needed for demanding performance environments.
The heavy-duty pressure plate uses a dual-clamp-load diaphragm and reinforced drive straps to create a reliable, high-strength clutch system. This unsprung kit includes a MIBA ceramic clutch disc available in a four- or six-puck configuration, providing fast on/off engagement for aggressive launches and rapid gear changes. Proper break-in is essential to help minimize clutch chatter and ensure consistent operation. The Stage 6 design is intended to harness the power of modified vehicles without sacrificing reliability or service life.
Action Clutch quality checks each kit through an experienced engineering review process before release. This attention to manufacturing and inspection helps provide dependable performance for drivers who require consistent clutch engagement under demanding conditions. The kit is designed for applications seeking approximately 200% increased holding capacity over a factory clutch, making it well suited for dedicated race vehicles and serious track-focused builds.
Fitment includes 2015, 2016, 2017, and 2018 Subaru WRX models with the 2.0L FA20DIT turbocharged engine. 2018 or newer WRX vehicles with a VIN beginning with J806877 require Action Clutch flywheel AC105FW or the original-equipment 2015-2017 flywheel for proper fitment. Refer to Subaru Technical Service Bulletin 03-79-18R before installation to verify compatibility. Professional installation and adherence to the manufacturer’s break-in procedure are recommended.
