When it comes to sprint car racing, one of the key components that sets these high-speed machines apart is their innovative aerodynamic wings. These wings play a crucial role in enhancing the performance and handling of the car, allowing drivers to push the limits of speed and maneuverability on the track. In this comprehensive blog article, we will delve into the world of sprint car wings, uncovering their unique design features, their impact on race performance, and the different types of wings used in this thrilling motorsport.

Let’s start by exploring the fundamentals of sprint car wings. These wings are strategically positioned on the top of the race car, creating downforce that helps keep the tires firmly planted on the track. By generating downforce, sprint car wings maximize traction, enabling drivers to maintain control and stability while navigating tight turns at breakneck speeds. The intricate design of these wings, coupled with their adjustability, allows teams to fine-tune their setups for optimal performance on varying track conditions.

The Anatomy of a Sprint Car Wing

In this section, we will take a closer look at the different components that make up a sprint car wing, including the main foil, sideboards, endplates, wickers, and more. Each element has a specific role in shaping the aerodynamics of the wing and optimizing its performance on the track.

Main Foil

The main foil is the central part of the wing and is responsible for generating the primary downforce. It is typically a curved airfoil shape, carefully designed to create a balance between downforce and drag. The curvature and angle of attack of the main foil are critical factors that determine the overall performance of the wing, as they directly affect the amount of downforce generated.


Sideboards, also known as fences, are vertical plates mounted on either side of the main foil. These sideboards help control the airflow around the wing, preventing it from spilling over the edges. By confining the airflow within the wing’s boundaries, sideboards contribute to increased downforce and improved overall stability.


Endplates are horizontal plates located at the outer ends of the wing. They serve multiple purposes, including reducing drag by preventing air leakage at the tips of the wing. Additionally, endplates enhance the efficiency of the wing by creating vortices that redirect the airflow and increase downforce.


Wickers are small, adjustable horizontal plates mounted on top of the main foil. These plates create turbulence in the airflow passing over the wing, altering the boundary layer and improving downforce. By adjusting the wickers’ angle and height, teams can fine-tune the wing’s performance to suit specific track conditions and driver preferences.

Types of Sprint Car Wings

There are several types of wings used in sprint car racing, each with its own unique characteristics and advantages. From flat wings to top wings and everything in between, let’s explore the different options available to teams and drivers.

Flat Wings

Flat wings are the simplest and most basic type of sprint car wings. They consist of a flat, rigid surface mounted on top of the race car. While flat wings provide some downforce, their effectiveness is limited compared to more advanced wing designs. Nevertheless, flat wings are commonly used in certain racing classes or on tracks with lower speeds and less emphasis on aerodynamics.

Top Wings

Top wings are the most commonly used wings in sprint car racing. These wings feature a curved airfoil shape, similar to the main foil, and are positioned above the driver’s cockpit. Top wings provide significant downforce and are highly adjustable, allowing teams to optimize performance for different track conditions. The adjustability of top wings makes them versatile and suitable for a wide range of racing situations.

Side Wings

Side wings, also known as side panels or sideboards, are mounted on the sides of the race car, near the rear wheels. These wings work in conjunction with the top wing to increase downforce and stability. Side wings are particularly effective in improving cornering ability, as they help maintain traction on the rear wheels during high-speed turns.

Shark Fins

Shark fins are unique wing designs that extend vertically from the top of the cockpit towards the rear of the race car. These fins improve stability by reducing the effects of crosswinds and side forces. Shark fins also aid in directing the airflow over the top wing, enhancing its efficiency and downforce generation.

Adjustability and Wing Angle

The adjustability of sprint car wings is a crucial aspect of optimizing their performance. Teams can fine-tune the wing’s angle to adapt to changing track conditions and driver preferences. Let’s explore the importance of wing angle adjustments and their impact on downforce and drag.

Angle of Attack

The angle of attack refers to the angle at which the wing meets the oncoming airflow. By adjusting the wing’s angle of attack, teams can modify the balance between downforce and drag. Increasing the angle of attack generates more downforce but also increases drag. Conversely, decreasing the angle of attack reduces drag but may result in reduced downforce. Finding the optimal angle of attack is a delicate balancing act that requires careful consideration of track conditions and the desired race performance.

Adjustment Mechanisms

Teams employ various mechanisms to adjust the wing’s angle during races. Most commonly, a hydraulic or mechanical system allows drivers to control the wing from inside the cockpit. Some wings feature incremental adjustment options, allowing precise modifications in small increments, while others offer continuous adjustment throughout a range of angles.

Track Conditions and Wing Angle

Track conditions play a significant role in determining the ideal wing angle. Dry, slick tracks with reduced traction may require higher wing angles to generate more downforce and increase tire grip. Conversely, on high-grip tracks or during wet conditions, teams may opt for lower wing angles to reduce drag and maintain optimal performance.

The Impact of Wing Design on Race Performance

The design of sprint car wings can significantly impact the overall race performance. Let’s explore how different wing designs affect top speed, cornering ability, and overall handling.

Downforce and Traction

The primary purpose of sprint car wings is to generate downforce, which improves tire grip and traction. Higher downforce levels allow drivers to maintain higher speeds through corners, as the increased grip keeps the tires firmly planted on the track. The design features of a wing, such as the main foil shape and angle of attack, directly influence the downforce generated and, consequently, the overall traction of the car.

Drag and Straight-Line Speed

While downforce is essential for cornering performance, excessive drag can hinder straight-line speed. Sprint car wings are designed to strike a balance between downforce and drag. By minimizing drag without compromising downforce levels, teams can achieve higher top speeds on the straightaways, maximizing the car’s overall performance.

Cornering Ability

The design of the wing, including its shape, sideboards, and endplates, plays a significant role in improving cornering ability. By channeling and manipulating the airflow, wings enhance stability and reduce the risk of losing control during high-speed turns. The ability of a wing to maintain consistent downforce across different cornering angles is a key factor in achieving optimal handling and cornering speeds.
