Vortec Technology on the back of the Ti 8-1-1 head reduces turbulent wake during the downswing for faster clubhead speed with improved stability and forgiveness to help generate distance.The variable-thickness T9S face has a high strength-to-weight ratio, allowing for a thin face to maximize ball speed.Removing 4 grams from the face helps position the CG low/back for ideal launch conditions and extreme forgiveness.Crown turbulators and Vortec Technology contribute to reducing drag 37% at impact, yielding greater clubhead speed and ball velocity for sizeable distance and accuracy gains from all swing speeds.G drivers are available in three models to fit your desired trajectory: G Standard, G SF Tec (Straight-Flight Technology), and G LS Tec (Low-Spin Technology).To fine tune your launch conditions in the 460cc head, adjust the loft up to ±1° using Trajectory Tuning 2.0, which utilizes a lightweight, aerodynamic, high-strength 7075 aluminum hosel sleeve.
