2015 - 2021 Dodge Challenger Hellcat
APR Side Rocker Extensions are the next step to help aerodynamically tune the handling of a car. Made of lightweight and durable carbon fiber composites, APR Side Rocker Extensions help reduce lift at high speeds by preventing air at the sides of the car from rolling underneath the car. The reduced lift helps to stabilize the car during high-speed cornering and helps to increase traction for faster lap times.
Carbon Fiber Construction
All APR Side Rocker Extensions are made in carbon fiber composites for lightweight and high strength.
Vehicle Specific Design
APR Side Rocker Extensions are designed and manufactured for specific vehicles for perfect fitment.
Mounting Hardware Included
Screws, nuts, and washers are included to allow you to install the APR Side Rocker Extensions to your car.
Computational Fluid Dynamics (CFD)
What is Computational Fluid Dynamics (CFD):
Computational fluid dynamics is a specialized sub-discipline of fluid mechanics (the study of fluid physics) that involves using algebraic equations to solve fluid flow problems. CFD has origins in the aerospace industry dating back to the 1960s, where companies such as NASA, Boeing, Lockheed, and others developed their own CFD programs to perform the analysis needed for their aircraft designs.
Using mathematical modeling and numerical methods, computations performed using powerful CFD software enable us to quickly predict and simulate what will occur in fluid flow situations (velocity, pressure, density, and temperature vs. time). In comparison to performing experiments in wind tunnel laboratories, CFD allows us to perform simulations in much more cost-effective, virtual laboratories.
CFD in motorsports:
CFD is used successfully in all the top levels of motorsports, including Formula One, IndyCar, and even NASCAR. CFD is even used by car manufacturers in the development of many of today's road cars. Companies have invested tens of millions of dollars, if not more, to implement CFD design in their product. As a disclaimer, CFD is not 100% accurate. Many factors can affect the accuracy of CFD simulations, including accuracy of mathematical models, limits in computing power, and the scientist's ability to interpret the data that that comes out of the computer.
Despite its lack of total accuracy, modern-day aerodynamic design could not have progressed to its current state without the help of CFD. The results of CFD-developed automotive products are real, and can easily be seen in both race cars and road cars.
