This kit is recommended for heavy-duty street use and mild track applications. Compatible with OEM flywheel on early production 2015-2018 Subaru WRX models. Note: Mid-2018 and later WRX models with VIN ending in J*806877 or higher require AC105FW flywheel or 2015-2017 OEM flywheel for proper fitment due to Subaru's change from 230mm to 240mm clutch size.

Break-In Requirements: 500 street miles with RPMs kept under 4500, no more than half-throttle, and no boost. Proper break-in is required to retain product warranty and ensure optimal longevity and holding capacity.
