ReveD RDX Option Parts This is a front bumper made of lightweight and highly rigid dry carbon material. By reducing the weight of the front overhang, the turning response is greatly improved! It reduces the steering lag during reversals and also increases acceleration when starting up! Since it uses highly rigid dry carbon material, it securely holds the body post even without a bumper brace. The included aluminum plate is reversible. You can use either side you prefer: the beautiful front side with the Rêve D logo engraved after anodizing (shiny edge) processing, or the mechanically designed back side. It can be used with the YD-2 series, as well as with any chassis that has the same front shape as the YD-2 series, regardless of the manufacturer. Please experience the improved machine operability by reducing the weight of the front.
