The Torque Solution rear differential lockdown system is for Subaru Impreza WRX and Sti models from 2008–2012. It reduces differential movement by locking key mounting points, which can improve traction consistency and drivetrain feel. This kit is intended to restore firmer differential positioning where factory bushings have deteriorated, aiding stability under load.
