In TaylorMade's limitless pursuit to help golfers improve, they've discovered the new shape of driver performance. An asymmetric sole design and powerful new Inertia Generator combine to increase aerodynamics and speed at the most critical stage of the swing. The reshaped sole design delivers more clubhead speed and enhanced aerodynamics at the most critical stage of the swing. The Inertia Generator positions weight at the extreme rear for increased forgiveness and is strategically angled at 20 degrees to reduce drag on the downswing. Each SIM Driver head has been individually calibrated and injected to reach the threshold of the maximum legal limit of ball speed. The revolutionary face curvature reduces sidespin and delivers straighter shots on off-center strikes. The Sliding Weight Technology provides adjustability and personalization to optimize the club for individual trajectory and ball-flight preferences, up to +/- 20 yards of draw-fade bias. The new Thru-Slot Speed Pocket technology delivers enhanced sole flexibility to create additional ball speed as well as improved forgiveness on low-face mis-hits. Standard TaylorMade warranty applies and satisfaction is guaranteed. Headcover and wrench included.
