Using this front lip is easy. First, find the pre - drilled holes on the lip and align them with the corresponding spots on your Subaru WRX or STI's front bumper. Then, use the included hardware to securely attach the lip. As for the maintenance, keep it clean by regularly washing it with a mild car wash soap. Avoid using harsh chemicals that could damage the carbon fiber finish. Also, be careful when parking or driving on rough roads to prevent any further chipping.
