Using the V - Limited Front Lip on your Subaru WRX or STI is straightforward. First, unpack the lip and check that you have the template and all the necessary hardware. Place the template on your car's front to mark where the lip needs to be installed. Then, carefully attach the lip using the provided hardware. Make sure all connections are secure. When it comes to maintenance, regularly clean the front lip with a mild car cleaner. Avoid using abrasive materials that could scratch the surface. Since this is a clearance item, it's non - returnable, so double - check your installation process. Also, remember that for the part to be under warranty, it must be installed by a CERTIFIED Subaru Dealership on a car with a matching VIN.
