Midway through the 2018 model year, Subaru upgraded the WRX clutch from 230mm to 240mm to improve durability. Because the sizes and bolt patterns differ, you must match the kit to your car's production date using the VIN.

Check the last seven digits of your VIN to determine fitment:

If your VIN is lower than J*806877:
Your car has the original 230mm factory setup.
This clutch kit is compatible with your OEM flywheel. No additional parts are needed for installation.
If your VIN is J*806877 or higher:
Your car has the newer 240mm factory setup.
This kit is not compatible with your factory flywheel.
To use this kit, you must also install the AC105FW flywheel to convert the system back to the 230mm size.

Disclaimers
Ceramic based clutch discs intend to increase the holding capacity and durability of the clutch as opposed to an increased life expectancy. Using a ceramic based material for easy street driving may contribute to premature wear of the clutch kit due to the harsher engagement and because of the higher tendency to slip the clutch during street driving.

Using a clutch kit with an unsprung clutch disc on a stock or lightly modified power engine that is daily/street driven vehicle can break the rivets on the clutch disc hub. Unsprung clutch kits are not designed for daily/street use or any constant on/off engagement environment. This can be compared to running a marathon in sandals vs a proper running shoe. If you were to run the marathon in sandals, you have no cushion or comfort and can cause injuries or wear you down faster than using proper running shoes.

*Increase in holding capacity is rated in Crank Torque, not Wheel Torque
