Hey everyone! The time has come to upgrade my shifter and reduce the distance between each shift. I decided to us the PERRIN Short Shift Adapter. I’d also recommend replacing the factory shift bushings at the same time (this will round everything off). This installation was very straightforward and for the most part went rather quickly.
Needed Tools and equipment
1) PERRIN Short Shift Adapter
2) 6mm Allen wrench
3) 12mm wrench and Socket
4) flat head screw driver
Step 1) Remove the factory shift knob.
Step 2) Remove the trim around the shift knob. You can easily do this by placing your hand in the shift boot and pull up on the trim. (should note that my car is a 2007 WRX) I found it very easy to pull up and towards the dash.
be sure you unplug everything
Step 3) Loosen and remove the 12mm nut and bolt that attaches the linkage to the shifter. Be sure to leave the linkage attached to the transmission.
Step 4) Take hold of the shifter and spin it 180 degrees. The bend in the lever should now face the rear of the car.
Step 5) With the shifter in place remove the steel pin and two bushings from the stock lever and reinstall them into the PERRIN short shift adapter.
(NOTE YOU DO NOT NEED TO REMOVE THE SHIFT ROD FOR THIS STEP)
Step 6) Slide the PERRIN short shift adapter over the shift lever and reattach the linkage. You will use the 12mm nut and bolt for this process.
Time for Adjustment
Quick rule of thumb, the shorter the desired length of throw the higher you will want to place the adapter on the shift lever.
Measure from the top of the stock shifter lever to the top of the PERRIN short shifter. Recommended heights are as follows. Shortest throw = 48mm while the longest throw will measure 61mm.
For setting the adapter for the shortest throw you will have to adjust the metal trim surrounding the shift lever. You can do this very quickly by using a crescent wrench to pry the front left corner of the metal bracket up and out of the way. This will now allow the linkage to travel with no interference.
Re-tighten all nuts and bolts, it’s also a good idea to run the shifter through all the gears to double check there’s no clearance issues. If needed re-adjust the metal trim. Replace the factory cover and knob.
QUICK, SIMPLE, and FUN!!!!
