Product design in detail: when developing a new wheel, particular attention is given to attaining perfection right from the very first design. For BBS this means not only making aesthetic improvements but also significantly increasing the wheel's performance. An example of such an improvement is hidden weight. To achieve the aim of hiding the not exactly attractive balancing weights, a new construction has been designed to hide the weights underneath the rim protectors. The result is aesthetically pleasing as well as performance enhancing.
