AutoTecknic Rear Diffuser Dry Carbon Performante BMW M3 G80 / M4 G82 / BMW G83 M4 2020-2022. Now you can choose a newly released dry carbon fiber rear diffuser for your BMW G80 M3, BMW G82 M4 & BMW G83 M4. The best rear diffuser is now available for your G80 M3 BMW, G82 M4 BMW & G83 M4 BMW. Manufactured using 100% 3K Twill-Weave (2x2) Pre-Preg carbon fiber.
A diffuser, in a car setting, is a formed segment of the vehicle back that works on the vehicle's streamlined properties by improving the progress between the high-speed wind current under the vehicle and a lot more slow freestream wind current of the surrounding environment.
This is our newly redesigned Dry Carbon Extended-Fin Competition Rear Diffuser for the F80 M3 and F82 M4. Features larger fins for added aggressiveness and functionality. Designed to mount directly into the lower rear factory bumper for a simple and fast installation. This carbon fiber diffuser is made with our 100% true pre-preg technology for the ultimate lightweight, high-durability, and precise fitment. AutoTecknic Dry Carbon Fiber Diffuser is both highly visible and highly functional.
There are three significant pieces of great vehicle back diffuser, specifically
1. Vertical Fins:The vertical fins help the airflow maintain a smooth path (laminar airflow) out to the back of the vehicle. In the absence of these vertical fins, the airflow underneath can vehicle can become turbulent, affecting the stability of the vehicle. Laminar airflow, on the other hand, decreases turbulence and increases the drag.
2. Smooth Underbody:While this is not a part of the car rear diffuser design, it contributes significantly to lowering the shape drag and works in tandem with the diffuser. Essentially, the smoother the underside of the car, the quicker the air will flow to the rear of the vehicle.
3. Expansion Chamber:The primary purpose of an expansion chamber is to create a difference in air pressure between the rear end of the car and underneath the car. This difference in air pressures creates a vacuum, which, in turn, helps to suck the air out of the back and create an grip.
This rear diffuser is AutoTecknic's newly released dry carbon fiber product for the G8X M3/ M4. The diffuser is designed to mount directly onto the lower factory mounting location for a fast and straightforward installation. Manufactured using 100% genuine 3K Twill-Weave (2X2) Pre-Preg Carbon Fiber with our signature autoclave technology, this diffuser is finished with multiple coatings of high-gloss UV-resistant clear coat. Following the weight-saving principles of motorsport ideals, we utilize the autoclave vacuum forming process to produce this lip with superior strength and fitment.
