This billet steering wheel is 15.5-inch in diameter, with a 2-inch dish; it is milled from a whole piece of aluminum 6061, assembled with half wrap covered by high quality wrapped which provides an extraordinary smoothness and comfort. The surface has a shiny mirror finish that well fits interior designs of vehicles. We also provide a default horn button along with the steering wheel, included in price, and can be changed with any other horn buttons available in our shop. There are 7 colors (White, Burgundy, Black, Light grey, Red, Dark grey, and Tan) for this steering wheel as well as walnut wood half wraps. The 9-bolts design is able to fit most 9-bolts adapters in the market, otherwise we also offer compatible adapters that do fit most columns.
