Depending on what motorsport venue you are at there are certain rules and regulations that participants must abide by. One, being that all windows must remain up while the car is on track. With that being said, the Rexpeed Window Vents allow air to enter into the cabin of your vehicle so you can have some form of ventilation in the cabin.
And they look great for street use as well. If you want that aggressive race car look then these will certainly enhance the exterior of your vehicle. They are made using high-grade FRP materials, and will be sold as a pair for the rear of the vehicle, on the left and the right-hand side.
