Using your Verus Engineering Rear Suspension Covers is easy. First, gather all the parts included in the kit - the left and right suspension covers, brackets, and the install hardware kit. Make sure your vehicle is parked on a flat surface and is turned off. You can start the installation by using the stainless - steel hardware and nylon washers provided. Simply bolt the covers onto your Subaru WRX or STI following the simple bolt - on design. As for maintenance, keep an eye on the black powder coating. If it shows signs of wear, you can clean it gently with a mild soap and water solution. Avoid using abrasive cleaners that could damage the coating. Also, periodically check the bolts to ensure they are tight and there is no rattling or movement of the covers. This will help keep your suspension covers in top shape and continue to enjoy the benefits of reduced drag and increased downforce.
