Brake cooling ducts and hose lowers your brake temperature by routing ram-air to your brake rotor and caliper. Using this non-horsepower robbing method has been universally accepted even with the parasitic drag increase. Hold off rotor cracks and crumbled/cracked brake pads due to overheating and keep your racing budget in check. Having the correct racing brake ducts with the appropriately sized brake cooling hose is one of the most economical brake improvements you can make. Trust DiscoveryParts to make you go slower faster.
