The BBS RI-D 20" wheel set for the BMW G8X platform represents one of the most advanced forged aluminum wheel designs available today. Developed and manufactured by BBS Japan, the RI-D utilizes a proprietary extra-super duralumin alloy normally reserved for aerospace applications. This specialized material provides exceptional strength while allowing the wheel to achieve extremely low weight.
Originally introduced by BBS in 2011 as the world’s first wheel produced using extra-super duralumin, the RI-D remains one of the lightest forged aluminum wheels ever produced for road vehicles. The unique five-spoke design emphasizes both structural efficiency and weight reduction, delivering a wheel that improves handling response, braking consistency, and overall driving dynamics.
Every BBS forged wheel begins as a billet of high-grade aluminum alloy and undergoes BBS’s proprietary multi-stage die-forging process. This manufacturing method can apply up to 18 million pounds of pressure during production, refining the grain structure of the material to create a wheel with exceptional strength, rigidity, and durability.
The result is a wheel engineered with an optimal stiffness-to-weight ratio, allowing drivers to reduce unsprung mass without compromising structural integrity. For high-performance vehicles such as the BMW G87 M2, G80 / G81 M3, and G82 / G83 M4, reducing wheel weight significantly improves suspension response, steering feedback, and overall chassis performance.
The RI-D’s minimalist cross-spoke design further contributes to its lightweight construction while maintaining the motorsport heritage that BBS is known for worldwide.
