The Zero/Sports Cold Air Duct brings in cold air to effectively cool down the front wheel hub and hence stabilizing the brakes efficiency. This also helps prevent thermal breakdown of the front tires to reduce the grip lost. The hard braking that occurs while driving in the race tracks and curvy roads produces a great amount of heat from the braking system. Fading will occurs and efficiency of the brake system will decreases dramatically if there is insufficient cooling. In addition, the power that drives the front tires and friction from the road surface is causing the temperature of the tires to rise and hence reducing the gripping force. With this minor addition to your vehicle, all these problems will be minimized.
