Project Corvette Stingray C7 Z51: Body Modification
In typical MotoIQ fashion, up to now, we have been working on Project C7 Corvette Stingray’s hard parts and underpinnings. Now it’s time to showcase some of the functional aero parts that Chevrolet Performance makes for the C7.
Typically aftermarket aero parts are lame; they don’t fit and have gaps. They require you to drill holes in your body panels for sheet metal screws. The carbon deteriorates in the sun and gets cloudy. Not so for these Chevrolet Performance offerings. They fit perfectly and are built to the same OEM durability standards as the car!
The belly pan is a great addition and a level of detail that is always totally missed by the aftermarket. It really helps the splitter work better.
Splitters work by trapping the air hitting the front of the car between the top of the splitter and the front bumper fascia. The air when trapped loses velocity and the energy of the airstream changes to a build-up of positive pressure on top of the splitter as the velocity stagnates or slows down. This pressure differential is what gives downforce. A splitter is less draggy than other ways of trying to make front downforce like big airdams or canards.
The winglets also make tip vorticities which work with the side skirts to help prevent air spillover from the sides of the car to the bottom that can create lift.
The diffusers work with the splitter to help enhance the pressure differential between the top and bottom of the splitter and belly pan by giving the under nose of the car a lift spoiling shape.
