The TaylorMade M4 driver features revolutionary new face curvature (Twist Face) which corrects face angle on off-center hits, to reduce side spin resulting in straighter drives.
Twist Face technology provides increases loft in the high-toe and decreases loft in the low-heel to produce more a consistent spin profile in common mis-hit locations.
A new Hammerhead slot in the sole allows for a lighter, more flexible face, resulting in a larger sweet spot.
The center portion of the slot increases ball speed low on the face and drops unwanted spin for more distance.
Further refeinment of Geocoustic sole technology make sfor a solid and explosive sound while enabling for a larger volume and more forgiving face.
