Using the COBB Front Roll Center Bump Steer Kit is easy. First, make sure your vehicle is a 2008 - 2021 Subaru WRX or STI. Park your car on a flat surface and use proper jacks to lift it safely. Then, replace the old parts with the components in the kit, including the 2 steering arm tie rod ends and 2 ball joints. As for maintenance, check the connections regularly to ensure they are tight. If you notice any looseness or unusual noises while driving, it's a good idea to inspect the kit right away. Also, keep the parts clean to prevent dirt and debris from causing wear. When it comes to safety, always follow standard auto - repair safety procedures. If you're not confident in your abilities, it's best to have a professional install the kit for you.
