Speed Dimple Pattern With their deep dimensions, the 338 Speed Dimples on each Z-Star golf ball punch through air for a penetrating launch. Once aloft, the dimples generate lift, driving the ball upward toward its peak and maximising glide distance during descent. When conditions get tough and the winds reach high speeds, the 338 Speed Dimples’ low drag coefficient helps the ball stay on target through the moving air and maintain distance in headwinds.
