/ BLACK FORGED ALUMINIUM WHEEL RIMS
Made from forged aluminium alloy. Engineered using advanced simulation and modelling tools such as FEM analysis, these wheel rims offer a weight saving over the standard (cast)* components while still ensuring unrivalled robustness. The resulting reduction in gyroscopic effect and unsprung weight translates to unparalleled responsiveness and agility.
