Quality - With FEM analysis, done according to the “finite element method”, the structural behavior characteristics of a new wheel model – for example in regard to strength or dynamics – are determined via computer and optimized during the construction phase. Using FEM analysis, the behavior of a wheel model under real operating conditions and stress can be simulated.
Weight Optimized - Because the spokes are back-milled, the optimal ratio between weight and stability is achieved for a light alloy wheel. This is achieved using a special CNC milling process, where the lateral parts that hold the wheel spokes, and are not relevant for stability, are removed to reduce the weight of the wheel‘s rotating mass.
Die Casting - To produce a really perfect and long-lasting wheel, you need to start with a top-quality casting blank. BBS uses low pressure casting to produce them. This involves pressing the aluminum alloy in a multi-part mold with up to 2 bars of pressure. After cooling it down to about 400 degrees Centigrade, the mold is opened and the casting blank is ready for further processing.
X-ray Inspection - Leave nothing to chance: after low pressure casting all rim blanks are examined by x-ray so as to be sure to detect any potential air pockets or surface defects. No mistakes are tolerated. Not a single wheel leaves our premises without being x-rayed!
Heat Treatment - Unlike many Asian or other European producers, our light alloy wheels are heat treated. This is crucial for the stability of the aluminium and hence guarantees the first-rate quality of our products.
Flow-Forming - Thanks to the flow-forming process, especially developed for the motorsport industry, our Performance Line wheels are weightoptimized. During Flow-Forming, the casting blank, which is produced according to the low pressure method, is rolled out under high pressure after being heated. The rim well is thereby thinned out, both the density of the material and the strength are increased. The finished wheel is thereby more stable and lightweight.
Paint Quality - In addition our environmentally-friendly paints, our paintwork processes also comply with 100% of the original equipment quality standards of the leading premium vehicle manufacturers. Furthermore, meticulous quality inspections ensure that our wheels always present an absolutely immaculate surface finish.
Multiple Pieces - If light alloy wheels consist of more than one component, the term multi-piece light alloy wheels applies. Two-piece BBS light alloy wheels consist of rim and star hub; three-piece light alloy wheels of two rim halves and the star hub. The individual components are securely connected with titanium bolts.
The two-piece CH-R II design combines the design language of the bestseller with the la - test technology from motor sport in an optimal way. Like its one-piece counterpart, the CH-R II is also subjected to flow-forming after pro - duction in the low-pressure casting process. This high-quality rotary rolling process allows the production of particularly light and strong wheels. In addition, the CH-R II features milled spokes to achieve maximum weight savings wi - thout sacrificing structural stability.
