The PERRIN Super Shifter Stop kit for 2015–2017 Subaru WRX (without STI or aftermarket short shifter) supplies a dedicated mechanical stop for the factory shifter to help limit throw and establish a repeatable stopping point. It’s presented as a direct-fit kit intended to simplify installation and provide a secure stopping surface, suitable for drivers who want a precise, consistent shift endpoint on supported WRX models.
