Some of this research and development in seeking the best Taylormade golf clubs has gone into testing and perfecting different types of club head materials, Callaway have even gone into partnership with car giants Lamborghini to produce a new class of material called forged composite which is used in their latest invention the Diablo Octane Driver. This material is said to be their lightest Taylormade discount and strongest material that they have ever used and enables them to optimize center of gravity for increased moment of inertia and greater distance potential. They have also thoroughly researched the effects of aerodynamics on the entire golf swing and have managed to significantly reduce the effects of drag through wind resistance, which produces faster swing speeds for Clone golf clubs.
