Using this light bar is a breeze. First, you can select up to four driving lights that fit the bar (you'll need to buy them separately). Then, simply bolt the light bar onto your 2008 - 2014 Subaru STI or 2011 - 2014 WRX. It's designed to match the contour of your car's OEM bumper, so it should fit right in. As for maintenance, the textured black powder - coated finish helps protect it from rust, but it's still a good idea to clean it regularly with a mild soap and water. Avoid using abrasive cleaners as they could damage the finish. Also, make sure to check the bolts periodically to ensure they're tight and the light bar is secure.
