For the sportier models, it is possible to order exclusive 20" inch carbon fiber wheels. A single-piece carbon fiber part with a glossy finish, the wheels are approximately 40% lighter than the standard version. The contribution to weight reduction is most noticeable in the handling and responsiveness when accelerating and braking since the wheel is unsprung weight. The inner part of the channel and spokes have a special coating of white paint used in the aerospace industry which reflects and dissipates the heat generated by the braking system in an extremely efficient way and guarantees lasting and constant performance even during intensive use on the track.
