Drive it further off the tee
If you are looking to add yards to your drive then one of the best things you can do is increase the extension in your backswing. This encourages the shoulders to start turning as soon as possible in the swing which will lead to a bigger shoulder turn.
Rotational power from your shoulders and core is what generates the club head speed at impact so it is important that you take time make sure that you are coiling yourself up in the backswing. For more golf driving tips read a book called the 5 keys to distance by Eric Jones.
