Megachip™ carbon guards are designed with aerodynamic performance, high durability, and a seamless fit and finish, providing invaluable protection to the paint along the sides of the car. These M5 guards are the pinnacle of our engineering and design efforts. The guards have a 1/2" width adjustment for stock wheels or wider setups. Details: Crafted entirely from 100% 3K twill carbon fiber with a high-gloss finish Manufactured using CNC-machined molds and compression curing Robust 1.5mm thickness for improved durability and impact resistance 45-degree outer edge (AeroEdge) helps reduce aerodynamic drag while deflecting debris Rear guards mount using custom Nylon-11 brackets for secure, discreet installation Front guards feature adjustable mounting position What's Included: 4x Megachip carbon guards 2x Alcohol prep pads 1x 3/32" punch tool 7x front pop clips Installation instructions Guaranteed satisfaction Aero Design Program For our carbon line of products, testing was performed using computational fluid dynamics (CFD) on a Toyota GR Corolla to simulate aerodynamic performance of the guards. The left-hand (driver's) side of the car is stock, while the right-hand side has Megachip guards. The design characteristics from the results of this study were directly carried over to the M5 guard program. Fig 1: air velocity on horizontal plane with and without guards The results from the analysis indicate a measurable, but negligible, increase in drag. Below is a photo showing the the pressure increase near the Megachip guards. Air velocity is approximately 100 MPH approaching the car: Fig 2: air pressure differences with and without guards Air direction / deflection are visualized in the following pictures, first with no guards and then with Megachip guards: Fig 3: Air pressure without guards; vertical plane Fig 4: Air pressure with guards; vertical plane Fig 5: Results during 60-simulation analysis The graph shows consistent results during a sequence of simulations: there is a very small increase in drag coefficient with Megachip guards. However, it is important to note that software results do not always align perfectly with real-world outcomes. The result is a splash guard taken to the highest degree of quality and design, making it extremely competent on the track and in the showroom.
