The folks at Bridgestone Tire and Rubber know rubber the way chicken farmers know a thing or two about eggs. In partnership with their colleagues in the company's golf division, they've now found a role for rubber in clubs. Engineers inject elastimer compound straight into Bridgestone's 460 cc J33R driver (it's the blue area shown in the photo below). This rubber curbs energy-inhibiting impact vibrations so the club/ball collision produces faster ball speeds and bigger drives. The wad of rubber also combines with a fixed tungsten screw and titanium casing to concentrate 25 grams lower and towards the rear to optimize ball flight. This mass is centrally located (rather than heel-biased), which allows you to dial in your preferred ball flight.
