Using your Rally Innovations Skid Guard is easy. First, make sure your car is parked on a flat surface. The skid guard comes with a simple bolt - on installation. Just follow the instructions and attach it to your car's front end. You can also mount up to two driving lights on it for better visibility, but remember the lights are sold separately. When it comes to delivery, a signature will be required. As for maintenance, regularly check the bolts to make sure they're tight. The powder - coated finish helps protect it from rust, but if you notice any scratches, it's a good idea to touch them up to prevent corrosion. Keep it clean by washing it with mild soap and water. This skid guard is designed specifically for your 2004 - 2005 Subaru Impreza, so enjoy the extra protection and the rally - inspired look it brings to your car.
