Using the FactionFab sway bar is straightforward. First, make sure your vehicle is the correct model (2011 - 2014 Subaru WRX Wide Body or 2008 - 2014 Subaru STI). The bar is designed to work with OEM components, so installation should be a smooth process. When installing, adjust the mounting points according to your driving needs for optimal performance. As for maintenance, the black powder - coating offers protection, but it's still a good idea to check for any signs of wear or damage regularly. The red polyurethane PTFE - lined greaseless bushings don't require greasing, but keep an eye on them for any signs of deterioration. Remember, this sway bar is all about improving your vehicle's handling, so enjoy the enhanced cornering and balance it provides.
