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.
The CI-R high-performance wheel currently represents the unmistakable culmination of a successful design line and follows the current trend with its concave shape. The wheel captivates not only visually with its distinctive, BBS typical Y-spokes, but is also equipped with all kinds of technical finesse. Weight optimization here is top priority. Thanks to the proven Flow-Forming technology and milled spokes, the CI-R is an absolute lightweight construction wheel. The three mold-cast dies used in production ensure three different concavities in the 20-inch wheel.
