Description The TaylorMade Qi4D Driver is the brand's most complete and fittable driver family yet - built around a revolutionary REAX shaft system, re-engineered aerodynamics and a new generation of face performance. The head profile has been redesigned through advanced simulations to increase ball speed and cut drag, while the modern address shape delivers a balance of inertia and speed that helps golfers find more distance without changing their swing. The improved roll radius generates more consistent spin on both high and low strikes - a genuinely useful upgrade from the Qi10 generation. The 60X Carbon Twist Face remains a cornerstone - lighter than titanium, generating incredible ball speed and more consistency across the face. Four Trajectory Adjustment System weights (9g x2, 4g x2) provide the most mass-efficient way TaylorMade has offered to adjust flight and spin, while the four-degree loft sleeve gives further control over trajectory and face angle. The REAX shaft is the real talking point though - based on 11 million shots captured over 20 years, it matches your rotation rate to find you more centred contact, more speed and better accuracy. Fitting in-store in Corsham and Swindon.
