While rubber may be great for tires, it simply stinks when being used as a shifter bushing! PERRIN understands and now offers a hard polyurethane version to replace the OEM versions in your car. Easy to install with simple hand tools while or after the installation of a performance short shifter. This will eliminate most of the sloppy feel during quick gear changes, and make each more precise. Less likely to miss that crucial 2nd-3rd shift.
An inexpensive compliment to any performance drivers working environment.
Fits: all 2004+ Subaru STi models.
