BBS Square Performance Wheel Sets for BMW E60 M5 S85 5.0L

Clear BMW chassis

Please ensure your correct model is selected

Square wheel sets include a complete set of wheels with identical dimensions for front and rear. Many OE wheels setups run square fitment as it keeps manufacturing costs lower, and offers predictable and even grip levels at all four corners. An added benefit of running a square set is reduced tire costs. Generally tires are cheaper when purchased as a complete set and are much easier to source.

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 Silver 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.
