Using this steering wheel hub is easy. First, make sure your steering shaft is 20mm in size. Then, choose the right angle (0, 10, 20, or 30 degrees) that suits your driving style. Attach the hub to your 3 - hole or 6 - hole steering wheel, making sure it fits snugly. When you are done driving, it's a good idea to clean the hub with a soft cloth to keep it looking good. Avoid using harsh chemicals as they might damage the aluminum. Also, regularly check the adjustment holes to ensure they are not loose. This will help keep your steering wheel hub in top condition for a long time.
