The beauty of GT racing is there is a body for everyone's taste and driving style I have been running USGT since the early days of the class I've run the McAlister DP bodies I have every Tamiya GT bodies made OK most. Anyone knows me I have raced or Tested more different GT bodies and it isn't the body in GT that is an advantage it is the car setup,motor or battery. Motor and battery and setup Trump body no matter how slick the body is. Well setup block of a body in the hands of a good racer will beat the slickest bodies made.
There are few tracks in the US that are big enough or fast enough for aerodynamics of a Aerodynamic body to make a difference.
