Using your Whiteline Adjustable Front Strut Bar is easy. First, make sure your Subaru is parked on a flat surface and the engine is off. Install the strut bar at the front of your vehicle according to the provided instructions. When adjusting the end plates, do it gradually and check the alignment. While using, avoid rough driving as it may put unnecessary stress on the bar. For maintenance, regularly inspect the bar for any signs of wear or damage. You can clean it with a mild soap and water solution to keep it in good condition. If you notice any issues, such as loose parts or excessive flex, it's best to get it checked by a professional.
