The Qi4D features a new and improved roll radius that tightens spin rates at different vertical contact points on the face. The result is more consistency between drives struck both high and low on the face.
A 60x Carbon Twist Face helps shots struck out of the heel and toe stay more online for narrower downrange dispersion. The carbon face also provides weight savings which adds to the ball speed equation.
The Qi4D driver features four moveable Trajectory Adjustment System weights that provide you the most mass efficient adjustability for optimized ball flight and spin.
A 4 degree loft sleeve adds another level of adjustability for loft, lie and face angle to optimize ball flight
