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.

FI-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 Gloss Black 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.

• Wheel studs are among the safest and most beneficial upgrades you can make on a track car. Not only are wheel studs safer than wheel bolts but they make changing wheels/tires much easier. One of the frustrating things about installing your wheels on the hub is that it's difficult to line up the wheel on the bolt holes. As wheels get larger but also heavier it's even more trouble. Add in a wheel spacer and the task is twice as hard. BMW does produce a wheel alignment pin for this purpose but if you're changing wheels often a stud conversion is the better way to go.
  
  Our original bullet nose studs are available in 60mm, 75mm, 82mm, or 90mm. The 75mm works great for cars that do not use a spacer (or a spacer smaller than 10mm). We recommend the 90mm length for cars that have spacers up to 20mm. The 82mm length is a happy medium between the 75mm and the 90mm. These studs come with a OEM-style black zinc coating for excellent corrosion resistance. These studs are perfect for dual-purpose street/track cars. The studs are stronger and safer than wheel bolts with protection against corrosion which makes them suitable for street use. For a dedicated race or track car, where wheel changes or pit stops are more frequent, check out our racing dry lube studs.
  
  Our studs are also designed and manufactured with the properly sized shank to work with a wider range of BMW wheel, nut, and brake rotor combinations. We intentionally avoid the extra large shoulders you see on other studs because they can interfere with some brake rotor hats. The extra large shoulder can be too large to allow the rotor to pass through and drilling out the holes is required (not cool!) Our studs have the sufficient shank for the brake rotor without interfering.
  
  Not all wheel studs are created equal. We don't take a manufacturer's generic wheel stud from their catalog and call it our own. Turner Wheel Studs are manufactured to meet our own specifications. Beware of cheaper studs on the market! We have seen other studs similar to our own designs that are not a true BMW fitment. There are differences that we have ironed out over our years of selling wheel studs for the BMW market. Our stud prices may be slightly higher than the rock bottom prices on the web but we promise that it's a higher quality.
   Turner Bullet Nose Wheel Stud Features:

• Black phosphorous corrosion resistant coating
