Using your Whiteline Adjustable Rear Strut Bar is easy. First, make sure your Subaru (WRX 2002 - 2007, STI 2004 - 2007, or Impreza non - turbo 2003 - 2007 sedan) is parked on a flat and stable surface. It should take about half an hour to install. If you're handy with tools, you can do it yourself. There's no need to get a wheel alignment after installation. When adjusting the end plates for tuneability, do it gradually and test your car's handling on a safe road. For maintenance, regularly check the bar for any signs of wear, like cracks or loose parts. If you notice any issues, contact the manufacturer or a professional mechanic.
