RAC - Relative Amplitude Coefficient - is a technology TaylorMade developed to improve shot-making and characterised by 'Feel Pockets' in the back of the club head. HT stand for 'High Trajectory'. With a large clubface, Taylor Made RAC HTs are wide-soled, low centre of gravity irons that easily launch the ball at a higher angle with less effort, resulting in high-flying shots that stay in the air longer for greater distance.
