The Exedy Hyper twin organic clutch kit for 2004–2017 Subaru WRX STI with EJ255/EJ257 2.5L engines is a multi-plate upgrade aimed at high-powered street and motorsport use. Twin-plate clutches increase torque capacity and heat handling versus single-plate units; these EXEDY kits are rated for elevated torque levels and come SFI certified, making them suitable where stronger, more durable clutches are required.
