Using the DC Sports Front Strut Bar is easy. First, make sure your vehicle's engine is off and the car is parked on a flat surface. Locate the strut towers in your 2003 - 2007 Corolla or 2002 - 2005 Matrix and carefully attach the strut bar according to the included instructions. When driving, you'll notice improved handling right away. As for maintenance, it's a good idea to check the connections every few months to make sure they're still tight. You can clean the strut bar with a mild soap and water solution to keep it looking good. Avoid using harsh chemicals as they might damage the steel. Also, if you're going to have any work done on your vehicle's suspension, make sure to tell the mechanic about the strut bar to prevent any accidental damage.
