Using the Perrin Short Shifter Adapter is straightforward. First, make sure your Subaru WRX is parked on a flat surface and the engine is turned off. Follow the included installation instructions carefully. It should take about 2.5 hours to install. As you drive, you'll immediately feel the reduced shift throws and the solid, positive shift feel. When it comes to maintenance, keep an eye on the adapter for any signs of wear or damage. Since it's nickel - plated, it's relatively resistant to corrosion, but you can clean it occasionally with a mild automotive cleaner. Make sure to follow the 5 - year manufacturer warranty terms in case you encounter any issues.
