Using this HT Autos bottom line body kit for your 2015 - 2017 Subaru WRX or STi is a great way to upgrade its appearance. First, unpack the box and make sure you have all the parts: 1 front lip, 2 side extensions, and 2 rear lips. When installing the front lip, use the factory push clips that come with extra ones. Then, drill the 5mm clearance holes and secure it with the nuts and bolts provided. The rear lip installation is similar, but you'll drill 6mm holes and use the plastic clips. For the side extensions, use the double - sided tape to attach them to the side skirts, and then use the 6mm drill to install the push clips. Remember, professional installation is a good idea as every car might need a bit of modification. As for maintenance, keep the kit clean by washing it regularly with a mild car cleaner. Avoid using abrasive materials that could scratch the polyurethane. If there are any small dents or scratches, you can try to gently reshape the flexible polyurethane or use a touch - up paint if needed. Check the hardware periodically to make sure everything is still tight and secure.
