Using the Perrin rear tow hook kit is easy. First, gather all the parts included in the box. The instruction guide will walk you through the 15 - minute installation process step by step. Once installed, it'll add a cool look to your Subaru WRX or STI hatchback. Remember, this hook is only for show and for pulling the car in a straight line. Don't use it for vehicle recovery. If you need to recover your vehicle, use the OEM tow hook or a method suggested by the manufacturer. To keep it in good condition, regularly check for any signs of corrosion. Since it's made of corrosion - resistant aluminum with a powder coat finish, it should last a long time. If you notice any issues, refer to the warranty and instructions for further guidance.
