Corvette Aerodynamic Body Panels

Front Splitters

Corvette Splitters are a modification to the body of your Corvette. Attached to the bottom of the front bumper, splitters look like a flat scoop that extends out from the bottom of the car.

Without a Splitter: As your Corvette reaches high speeds, air pressure builds up at the front of the car. A lot of this high pressure creates low speed air that ends up underneath the car. With only low pressure air above the car exerting itself on top, the car experiences lift, causing the front of the car to lighten up. This results in reduced traction on the road.

With a Splitter: Splitters act like a wedge that forces the high pressure air upwards where it builds up around the bumper and migrates up and over the top of your Corvette. The low pressure creates high speed air that passes underneath your car. Combined with the high pressure air that is passing over the top of your Corvette, lift is reduced, resulting in a positive downforce. This gives your Corvette more traction as it hugs the road. A combination of a splitter with a front air dam, or openings on the front bumper, direct the extra air into productive avenues, such as into the brake or radiator cooling ducts.

Aerodynamic body upgrades, in general, are for redirecting air to carry out various functions. Front splitters have a lot to offer in looks and functionality. However from a styling and aerodynamic aspect, front splitters are not the only game in town! It is actually possible to get the same performance gains with a quality front lip spoiler. Like a front splitter, a front lip spoiler attached to the front bumper of your Corvette improves downforce and aerodynamics while providing protection and styling to the front bumper. Front splitters include an under body tray that aids in rigidity and improving downforce. Front lip spoilers perform to a lesser extent, but are a cost efficient upgrade for aggressive good looks.

Wheel Deflectors

Front wheel deflectors attach to the OEM wheel well liner mounting points located inside the front fascia at the front of the wheel well opening of your Corvette. These deflectors mount at the lower attaching point where the wheel deflector meets the spoiler or splitter.

Wheel Deflectors

Front wheel deflectors are designed to push airflow around the rotating wheel more efficiently to reduce lift and drag. Front wheel deflectors are available in two designs. One with spats and one without spats.

Wheel Deflectors

Wheel deflectors with spats have an “L” shaped end that supports and braces the underside and the end of your spoiler or splitter.

Wheel deflectors without spats function the same, but the lower end does not fit under the spoiler or splitter and simply "butts against" the spoiler or splitter.

Front Canards/Winglets

Front canards are tall wings (think RPO Z07) or smaller winglets (think Z06 front splitter) attached to the front splitter or spoiler of your Corvette for the purpose of modifying the aerodynamic characteristics of your car.

The most common use of canards is to increase front downforce on Corvettes where the balance of traction is considered to be unfavorably biased towards the rear wheels. The canards, once installed, provide additional downforce at the front of the vehicle, adjusting the balance of traction and thus improving the handling characteristics of the car.

Front Canards and Winglets

Side Skirts

Side skirts prevent lateral high pressure air from moving underneath your Corvette. The addition of side skirts also assists in re-purposing the air from behind the front wheels to create additional downforce and added vehicle stability.

Side skirts are somewhat similar in principle to splitters. As your Corvette reaches high speeds, air pressure builds up at the front of the car. A lot of this high pressure, low-speed air ends up underneath the car, and with only low pressure air above the car exerting itself on top, the car experiences lift, causing the front of the car to lighten up. This results in reduced traction on the road. Side skirts also help reduce unwanted paint damage from rocks and other road or track debris.

Side Skirt

Side Vents

Side vents can be seen behind the front or rear wheels, allowing for airflow to exit the wheel wells which typically remains turbulent from the rotation of the wheels. These can also be used to channel out hot air from the engine bay or direct cool air to the brakes.

Rear Diffusers

A rear diffuser is a portion of the rear end shaped to create a location of increasingly larger air volume below the rear of your Corvette that reduces turbulent airflow. This allows for fast-moving, low pressure air underneath the car to accelerate and expand at the rear of the vehicle.

The diffuser helps to accelerate the air underneath the car which reduces its pressure and improves downforce.

Rear Diffuser

Rear Spoilers & Wings

Spoilers and wings are different than the other handling adjustment tools for several reasons.

  • The magic of a spoiler or wing is that they produce a load on the tires, which translates to increased cornering speeds.
  • Stronger acceleration out of the corner without wheel-spin.
  • The downforce produced by the wing increases with vehicle speed and therefore the speed of the air over the wing increases. However, this creates a concurrent increase in aerodynamic drag that slows the car's straight line speed but greatly improves cornering speeds.
Rear Spoiler and Wing

Rear Wicker

Wicker Height: These spoilers can be changed rapidly to tune the aero of a wing, with larger wickers generally giving more downforce.

Wicker Span: On wings it is common for wickers to not run the entire length of the wing. As the span (or width) is reduced, the effectiveness or downforce of the wicker will also be reduced, however the drag and turbulence created by the wicker is reduced. Because of the large impact of front end turbulence on the flow over the car and to the rear wing, a smaller/ narrower wicker does sometimes produce more overall downforce than a larger one.

Rear Wicker

NACA Ducts

These air scoops are designed to have minimal impact on airflow over the top of your Corvette while still creating an inlet for airflow. They can be used in nearly any application that requires airflow to enter the engine bay for cooling. Whether that's feeding an air intake, a radiator or even cooling for a driver.

NACA Ducts

Hood Extractor

Hood extractors allow for a clean exit for the air passing through the radiator, and they also help to maintain airflow through the engine bay, increasing cooling capabilities.

Stand Out With Carbon Fiber

Carbon fiber accessories will certainly give your Corvette an aggressive, racing inspired look, but it doesn't stop there. Carbon fiber is approximately 20% stronger and stiffer than even the best fiberglass and absorbs energy at a higher rate. Carbon fiber and fiberglass share some similar attributes, but carbon fiber will always be stronger, stiffer, and lighter. Give your Corvette a whole new competitive edge.

Spoiler Alert! The differences between Spoilers, Splitters, Wings and Diffusers

Spoiler Alert! The differences between Spoilers, Splitters, Wings and Diffusers

Aftermarket parts add a custom look to Corvettes, but many times they also serve a functional purpose. Spoilers, Splitters and Diffusers all provide performance benefits, from increased aerodynamics to better downforce on the car. Whether you’re looking for pure style or want added kick, it’s important to know the function of each part.

Reduce Drag, Improve Handling

A diffuser, in an automotive context, is a shaped section, typically located in the muffler area of a Corvette. It improves aerodynamic properties by enhancing the transition between the high-velocity airflow underneath the car and the much slower, freestream airflow surrounding the Corvette.

Basically, as air flows into the underbody from the front and sides of the car, the diffuser creates a space for the underbody airflow to decelerate and expand in area (density remains constant at the speeds of travel) to reduce excessive flow separation and drag, by providing a degree of “wake infill” or more accurately, pressure recovery. The diffuser itself accelerates the air flow in front of it, generating downforce and keeping the Corvette snug to the road.

Give Your Diffuser a Boost

Splitters serve a similar purpose as Diffusers, only at the front of the car. A Splitter is designed with an upward facing surface, allowing high pressure to increase the amount of downforce at the front of your Corvette. By redirecting air away from the air dam, the Splitter causes the air to accelerate, creating a downforce.

The larger the area of the splitter, the more downforce is generated for improved handling. In most closed-wheel race cars, the underside of the splitter smoothly integrates with the undertray, creating one large flat plane that is driven by the rear diffuser. Some race cars actually use an additional diffuser immediately behind the splitter to help create even more downforce, keeping them on the track while cornering at high speeds. The air extracted by this extra diffuser is expelled through vents in the sidepods or above the car around the cockpit.

Science Of Airflow

The diffuser on the underbody of the car guides that incoming air at the rear upwards so it creates the strongest possible vacuum (suction effect). The air flows faster under the wings than over them and also creates a vacuum.

A Spoiler is designed to “spoil” air flow across the body of your Corvette, usually described as turbulence or drag. Spoilers are available for the front end and the rear end of a car. Also called air dams, Front Spoilers reduce the amount of air flowing underneath the vehicle, which generally reduces aerodynamic lift and drag. Spoilers have become a mainstream automotive accessory, appearing on passenger vehicles in addition to race and high-performance sports cars. While some Spoilers are added primarily for styling purposes and have little-to-no aerodynamic benefit, they all serve as the last line of defense between your Corvette and parking blocks, speed bumps and offset driveways. A Rear Spoiler is a rear mounted air deflector that mounts flush to the body of your Corvette. Adding a Rear Spoiler creates a gentler slope from the roof to the rear of the Corvette, increasing aerodynamic performance.

Installing a Front Spoiler on your Corvette is easy.

Wings differ from Rear Spoilers in that they are mounted to 2 pedestals on the Corvette’s body and do not actually touch your car. Air flows over the top and bottom of the Wing, creating a pressure differential that causes some downforce. However, Wings provide the least performance benefits of the options available and are mostly added for looks, except for the cases of Active Wings.

air flow diagram

An Active Wing adjusts in conjunction to the change in speed of a vehicle to fully maximize downforce and airflow. Active Wings are prevalent in racing, depending on the class or regulations at the race. They are derived from the airfoils and flaps on aircraft that direct air around the plane. They use motors to adjust the position and angle of the Wing for optimal performance. One of the most common vehicles with an Active Wing are certain Porsche models. More technologically advanced vehicles, like the McLaren MP4-12C and the Bugatti Veyron, feature a variety of Active Wing designs that are positioned by data readings from the car’s internal computer. On these automobiles, the Wing can tilt almost vertically under heavy braking to act as an air brake system.

Now that you know the differences, which one is right for your Corvette?
