BBS - BBS-RI051DBK

One Piece Forged Aluminum Wheels. Produced by BBS-Japan using a special 7000 series alloy that helps make this wheel as light and strong as possible. Covered by U.S. Pat. D606,921 and European OHIM Reg. No. 000 803 952. BBS has been flow-forming wheels since 1996. Flow forming is a procedure that uses a continuous rotational motion with 3 hydraulic rollers and tremendous pressure at high temperatures to "Form" the inner rim area of the wheel. This process changes the mechanical properties of the cast rim area to increase strength, stiffness and impact over "stiffness to weight ratio" which can deliver very high level of performance at a cost that is much lower than a forged wheel.
