Description
From the factory, the Toyota GR Corolla’s rear engine mount (torque arm) is designed with soft, high-compliance rubber bushings focused on comfort rather than performance. While effective at reducing noise and vibration, this design allows excessive engine and drivetrain movement under acceleration, deceleration, and aggressive shifting.
The Whiteline Rear Engine Mount Insert Bushing Kit is engineered to address this weakness by filling the voids in the OEM mount with low-compliance bushing technology. By limiting forward and aft drivetrain motion, this insert significantly reduces slop, twisting, and shudder commonly experienced with the factory rubber bushing.
The result is a more direct and responsive feel on and off the throttle, improved gear engagement, and better overall drivetrain control—especially noticeable during spirited driving or track use. Designed as a direct-fit insert, this kit installs easily without removing the factory mount and is ideal for enthusiasts seeking improved performance without a full mount replacement.
