A golf club is fabricated with at least one vertical stability plate and / or at least one horizontal stability plate at a club head. The golf club is provided with a stability plate and an asymmetrical wing, or a combination of the same, which are installed at an upper side or left and right sides of the head of the golf club such as a driver, wood or iron, for example.An aerodynamic force generated in a downward direction by the loft of the club face is compensated by asymmetric wings applying an aerodynamic lifting force to an upper direction of the club head during a swing of the club. Even when a golfer has a swing speed or posture problem when swinging a club, the head of the club is guided to rotate along a desired proper orbit. A golf ball can be hit by a sweet spot of the head face of the club due to the stability and compensating force for achieving a straight drive, and enhanced flying distance.
