Action Clutch's Stage 3 (1MS) Clutch Kit is designed to withstand even the most challenging conditions. Featuring a heavy-duty single diaphragm pressure plate, reinforced drive straps, and a Sprung MIBA Ceramic disc, this kit provides peak performance and extreme durability. This FFW (Fits Factory Flywheel) version is engineered to work directly with your stock OEM flywheel, eliminating the need for flywheel replacement.

Key Features:

• 170% increased holding capacity over factory kit
• Sprung MIBA Ceramic disc available in 4-puck or 6-puck configuration
• Heavy-duty single diaphragm pressure plate with reinforced drive straps
• Patented fully enclosed spring retainers prevent spring displacement under high-stress conditions
• Light to medium pedal feel with aggressive engagement
• Compatible with stock OEM flywheel - no flywheel purchase required
• Designed for 2018-2021 Subaru WRX 2.0L FA20DIT turbocharged AWD models

Performance Applications:

Ideal for heavy-duty street use and occasional drag, road, or drift racing. This clutch kit is perfect for modified WRX builds running increased boost, bolt-on modifications such as intake/exhaust upgrades, and custom engine tuning.

Important Notes:

The Sprung MIBA Ceramic clutch kit provides quicker engagement and will introduce some clutch chatter, which will minimize after proper break-in. Break-in requirements include 500 street miles while keeping RPM's under 4500, no more than half-throttle, and no boost. Professional installation is strongly recommended as clutch replacement requires transmission removal and specialized tools.

Products are 100% hand assembled and made in the USA. Every kit is quality checked by experienced engineers with over 60 years of collective experience.
