The XClutch 8-inch twin solid ceramic race clutch kit for 2015–2021 Subaru WRX STI 2.5L is a compact motorsport-focused upgrade that balances torque holding, heat capacity and reduced weight for club racing or drifting. It pairs a performance flywheel with solid-centered ceramic discs and an aluminium cover to improve clamp force and pedal feel. The kit includes release bearing, pilot, aligning tool and a heavy-duty pull-to-push actuation conversion for push-type operation.
