TRD Door Stabilizer Kit Scion FR-S / Toyota GT-86 13+

The TRD Door Stabilizer kit uses the door as a stiffening implement. Once the door has been closed, it slides a spring-loaded metal section behind the lock and grabs against a teflon-like plastic part on the door itself.

This pushes the door slightly against its hinges and further stiffens up the chassis. The result is a better and more direct steering feel though the corners.
