BBS - BBS-CH149BPO

The BBS CH-R wheel, MPN CH149BPO, is a one-piece counter pressure cast wheel featuring a flow-formed rim and a back-milled spoke area, which contributes to its optimized weight through FEM analysis. This wheel is also equipped with a durable stainless steel rim protector. The flow forming process, utilized by BBS since 1996, involves a continuous rotational motion with hydraulic rollers and intense pressure at high temperatures to "form" the inner rim. This advanced manufacturing technique enhances the mechanical properties of the cast rim, resulting in increased strength, stiffness, and impact resistance while maintaining an excellent stiffness-to-weight ratio. This delivers a high level of performance at a more accessible cost compared to a forged wheel. The wheel specifications for this particular part number are 20x10 inches in size, with a 5x112 bolt pattern, an ET18 offset, and a CB66.5 hub bore. The finish is described as Satin Black with a Polished Outer Lip Ring.
