In mid-2018, Subaru updated the WRX clutch from 230mm to 240mm to improve durability. This larger setup became the standard for the 2018-2021 model years.

Check the last seven digits of your VIN to determine if this kit fits:

• If your VIN is J*806877 or higher:
  
  • Your car has the larger 240mm factory setup.
  • This clutch kit is compatible with your OEM flywheel.
  • Note: This kit will not fit the Action Clutch chromoly flywheel AC105FW.
    

• If your VIN is J*806876 or lower:
  • Your car has the older 230mm factory setup.
  • This clutch kit will not fit your car.
  • To use an Action Clutch product, you would need to run their 2015-2018 WRX clutch and flywheel combination instead.

Installation

Professional installation is strongly recommended as clutch replacement requires transmission removal, specialized tools, and torque specifications. Installation typically takes 4-6 hours and requires proper flywheel resurfacing or replacement. Clutch break-in period of 500-1000 miles is recommended for optimal performance and longevity.
