Body Aerodynamic Properties: 
* Front fenders developed using CFD for optimal lift and drag
* Front fender louvers located, using pressure taps, at maximum negative pressure to reduce lift
* Angle of nose profile developed in wind tunnel for minimal drag and maximum downforce
* Greenhouse shaped for equivalent airflow around the top and sides for minimal pressure variations, resulting in reduced lift and drag
* Rear spoiler necessary to help balance the downforce of the splitter
