Using this HT Autos bottom line kit is a great way to upgrade your Subaru WRX or STI Sedan's appearance. First, make sure you have all the parts from the box: 1 front splitter, 2 side skirt extensions, and 2 rear lips. Since professional installation is highly recommended, it's best to take it to an expert who has experience with body kits. They'll know how to make any necessary modifications and use the included hardware to install the kit properly. As for maintenance, the tough polyurethane material is quite durable. But to keep it looking good, you can wash it regularly with a mild car wash soap and a soft cloth. Avoid using harsh chemicals as they might damage the unpainted black finish. If you plan to paint the kit, make sure to use automotive - grade paint and follow the painting instructions carefully. Also, be careful when parking and driving to prevent hitting curbs or other objects that could cause dents or scratches.
