The rear diffuser effectively increases the vehicle’s downforce and increases the car’s grip on the road by reducing aerodynamic drag. The air pressure created beneath the car gets affected by the diffuser, which helps the air pressure to normalize as the vehicle moves forward cutting the air.
The car rear diffuser makes use of Bernoulli’s Principle to decrease the air pressure beneath the car and increase the speed of the air. The differences in the air pressure between the high-pressure at the car rear and low-pressure under the car creates a vacuum effect. With low air pressure under the car and high-pressure above, increased downforce is created and the aerodynamic drag is reduced.
Car rear diffusers are an excellent way to maintain an optimum downforce without compromising the car’s performance. This product is specifically designed to fit this car model creating a factory OEM look.
The product is ready to use (unless you want to paint it), comes with mounting kit and manuals. It´s made in strong but flexible ABS plastic and is TUV certified.
