Racing Radios and Communications is an essential part of racing. Race car drivers and crew members need to maintain constant contact with each other in order to gain advantage on the track.
In Endurance racing it is important to have radio contact with the driver. The driver can let the pit crew know about issues with the car and if they are coming in unexpectantly. The crew can let the driver know of track conditions, fuel usage and any incidents ahead. Installing a radio into a helmet takes a little care but can be done with a few simple tools.
