At 460cc, the new Callaway X460 drivers are the largest allowable under the Rules of Golf. They combine a new CT/VFT face, a distinctly designed and patented Consistent Alignment Sole and proven and patented Callaway Golf technologies. Extensive testing at the Callaway Golf Test Center in Carlsbad, California, show the X460 and X460 Tour to be the longest conforming all-titanium drivers Callaway Golf has ever made. The new CT/VFT face, the Company's next-generation patented Variable Face Thickness (VFT(R)) Technology, takes ball speed to the edge of the legal limit as defined by the United States Golf Association's Characteristic Time (CT) test. The X460's titanium face is robotically plasma-welded to the body, utilizing a precision manufacturing process. This ensures face thickness is controlled to tight tolerances for robust performance over a larger face area. Result: more distance, more often.
