Pirani RC MRX-6X radio plate stiffener
From Pirani RC for the Mugen MRX-6X is this carbon fibre radio plate stiffener. Machined from 2,5mm thick carbon, it mounts directly to the front of the radio plate, bridging the front of the plate at three points to create a much stiffer assembly. This part helps make the car easier to drive in high grip conditions.
