High Performance BMW Wheel Upgrades for BMW 4 Series F32 (2014+)

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.

CI-R wheels consist of a pressure cast wheel surface and a flow formed rim structure.  Combining these two fabrication techniques yields a wheel that is extremely strong while remaining 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 Platinum Silver with a polished rim protector 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 or pulling.

Specs:

• 19x9 ET20 - qty 4
• Platinum Silver with a polished rim protector
• Center Bore: PFS
• Bolt Pattern: 5x120

Vorsteiner is on the cutting edge of BMW styling enhancements and their new award-winning Flow Forged wheels are in a class of their own. Vorsteiner aero upgrades and wheels have been featured on many of our latest project and show cars. The V FF wheels strike all the right chords for style, fitment, technology, and quality.

Flow Forged wheels by Vorsteiner are built for style, strength, and reduced weight. This performance oriented wheel group is perfect for both road or track applications thanks to its light and strong aluminum build and precision formation.
