The DRS-1 features a more aggressive streamlined design with screw-less dry carbon fiber endplates, elevating its aesthetic appeal for the GT4 RS street car. In traditional wings, aluminum inner structures are used at the mounting points, however, in the SR Flex-Carbon Wing, aluminum has been replaced with the SR Flex-Carbon structure, reducing the weight by another 1.5kg, mostly importantly, the flex-carbon structure provides unparalleled flexibility, similar to that seen in the McLaren F1 Flex Wing.
