Minimum mass, maximum stability: That’s what sports car drivers want. And the BBS wheel design FI-R brings along these qualities.
SPECIAL FEATURES
An FI-R wheel for the Porsche 991 GT3, mounted on the front axle in the dimension 9 x 20 inches, weighs in at just around 7.9 kilograms. The counterpart in 12 x 20 inches for the rear axle weighs only 9.2 kilograms with a wheel load of 620 kilograms.

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. |

FORGING TECHNOLOGY Forging is a non-cutting forming process for material in a heated, solid condition. In order to generate the highest degree of material density and weight reduction at top performance from our high-strength and durable aluminum or magnesium alloys, they are further enhanced in a complex forging process. This entails placing the heated star hub or the entire wheel blank in a press and compressing it in several work steps at 5000 to 8000 tons of closing pressure to further densify the material in a special form known as a matrix. In between the individual work steps, the blank is repeatedly heated to approx. 400 degrees centigrade. As a result an optimal material structure is achieved particularly at the areas of high strain, the wheel can be dimensioned smaller, and is thereby lighter in weight. |
