Using these K - Tuned roll center adjusters and extended ball joints is straightforward. First, make sure your car is properly supported on jack stands for safety. Remove the old bushings and suspension components carefully. Install the new roll center adjusters and ball joints in their place, following the normal installation procedures for your specific car model. Remember, these parts are 15mm taller than stock, so you might need to re - check your steering alignment. For maintenance, regularly inspect the bushings for signs of wear or damage. If you notice any cracking, excessive play, or other issues, it's a good idea to replace them. Keep the components clean to prevent dirt and debris from causing premature wear. These parts are built to last, but proper care will ensure they serve you well for a long time.
