BBS Wheels FIR - Porsche Wheel - 21x9.5, 5x130, Black Satin - FI159BS
One piece forged aluminum wheels designed and produced in the Motorsports department for performance minded Porsche owners.
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.
