BBS Wheels combine decades of race proven quality and German engineering with stunning good looks. Utilizing the most cutting-edge manufacturing technologies based on a foundation of constant innovation continues to propel BBS into the future.
RG-R style wheels combine a lightweight forged construction with an eye-catching yet tasteful design to bring you some of the finest two-piece wheels on the market.
Forged wheels are created by crushing a solid block of aluminum into the desired shape using an extreme amount of pressure. This creates a wheel that is incredibly strong while remaining relatively lightweight. Using FEM analysis the engineers at BBS are able to precisely measure and optimize wheel properties before this process even begins. Once the forging process is complete, the meticulous finish work begins.
Back-milling is a process used to optimize the ratio between weight and stability. Using advanced computer analysis and a special CNC milling process the lateral parts that hold the wheel spokes, and are not relevant for stability, are removed. Extensive real-world simulation is used at this point to further ensure that no strength or stability has been lost.
Finally, BBS pays special attention in machining the undercut or back side of the wheel. To machine the undercut, all areas on the inner side of the wheel and the star hub that correspond to weight optimization are processed with special turning or milling tools and excess material is removed to reduce the rotating wheel mass. Special attention is hereby given to the optimization of the inner sides of the spokes and the bolt circle. With the application of these methods, BBS is able to produce more complex forms with increased stability and less material input.
These wheels come in a Diamond Black painted finish with a diamond cut lip and BBS ensures that their paint quality exceeds OE manufacturer specifications for durability and longevity. A final protective clear coat layer ensures that these wheels will be easy to clean and look amazing for years to come.
Please Note: Aggressive fitment, may require fender rolling/pulling.

BBS 16" Style RG 527 SK Wheels combine decades of race-proven quality and precision German engineering with a striking, timeless design. Crafted using advanced manufacturing techniques, these wheels are designed to offer an exceptional balance of strength, durability, and lightweight performance. Built with a forged construction, the BBS RG 527 SK wheels stand out as some of the finest two-piece wheels available on the market.
Forging aluminum under extreme pressure results in a wheel that is both robust and light. BBS engineers optimize wheel properties with FEM analysis even before the forging process begins, ensuring top-notch performance. The back-milling technique further enhances the strength-to-weight ratio, providing increased stability without adding unnecessary weight.
Finished in a stunning silver paint with a diamond-cut lip, these wheels are designed to exceed OE manufacturer specifications for longevity and durability. A protective clear coat layer ensures they stay looking pristine and are easy to maintain.
