Car Spoilers Rear Wings
$173.52
Our car spoilers wings span 60, 65, 70, and 72 inches with a chord of 9 7/8 inches, giving you the most optimal downforce with the least amount of drag. The extruded airfoil shape with a 1/4″ gurney allows for optimal airflow that reduces drag yet supplies an effective amount of downforce for your Race/Track vehicle. Engineers performed Computational Fluid Dynamics (CFD) analysis on this wing to validate its aerodynamic design. You can see detailed CFD data here.
Each WingLogic racing car rear wing spoiler uses lightweight and durable extruded 6063 aluminum. These CFD tested rear race wing automotive spoilers contain the highest quality alloy for superior strength and low weight. All kits include 6061 aluminum mounting brackets and anodized end plates.
Aerodynamics Explained
A rear wing car spoiler or wing mounted on a car generates downforce when air moves more quickly across the bottom of the wing than it does across the top. As a result, the slower-moving air across the top of the wing exerts more pressure than the faster-moving air underneath, ultimately resulting in downforce.
But how do we get the air to do that? The answer is to make the wing an airfoil shape. When air runs into a curved surface, it tries to follow that surface, thereby creating the Coanda effect. Additionally, the direction you mount the wing determines whether it generates positive or negative lift. Specifically, the air that has to travel further speeds up, and this creates a pressure imbalance that produces lift or negative lift, which is downforce.

Advantages of car spoilers rear wings
- Improves traction by increasing the grip of the rear tires.
- Allows for higher cornering speeds by reducing the risk of sliding or losing control.
- Enhances acceleration and braking performance by keeping the rear tires firmly planted.
- Reduces lift at high speeds, preventing the car from becoming unstable or “light” on the track.
- Counters the natural tendency of the car to lift at the rear due to airflow passing underneath.
- Works in tandem with the front splitter or wing to maintain a balanced aerodynamic profile.
- Allows the car to take corners at higher speeds without losing grip.
- Reduces understeer (when the front tires lose grip) and oversteer (when the rear tires lose grip).
- Prevents the car from becoming unstable or “floaty” at high speeds.
- Moreover, improves driver confidence and safety during straight-line acceleration and braking.
- For example, on high-speed tracks (e.g., circuits with long straights), the wing can be set to reduce drag for better top speed.
- On twisty tracks with many corners, the wing can be set to maximize downforce for better grip and handling.
- In contrast, advanced aerodynamic designs (e.g., multi-element spoiler wings) create efficient downforce with minimal drag.
- Engineers design some wings with DRS (Drag Reduction System) in Formula 1, which temporarily reduces drag on straights for higher top speeds.
- Enhances braking efficiency by improving tire grip.
- Futhermore, this reduces stopping distances, especially at high speed.
A rear wing spoiler is a crucial component in race car design, providing downforce, stability, and improved handling. Its benefits far outweigh the trade-offs, especially in high-performance racing where every fraction of a second counts. Teams carefully design and adjust rear wings to suit specific tracks and conditions, making them a key factor in achieving competitive advantage.
