BMW Brake Cooling Ducts & Backing Plates

Plan on tracking your car? Going to be using real track/race pads? You're going to need brake cooling ducts and hose. Brakes create lots of heat and temps can rise to damaging levels. Excessive heat will burn up caliper seals and dust boots, boil brake fluid, lead to rapid pad wear, inconsistent pedal feel, damage rubber boots on suspension ball joints, and other problems. Racing brake pads are designed to work in very specific temperature ranges so to prevent them from exceeding those temps race teams rely on brake cooling ducts, silicone hose, and bumper ducts.

We have designed and produced advanced brake backing plates that fit behind the wheel bearing hub. The backing plates have an inlet duct that directs air to the center of the hub/rotor. From there, cooling vanes in the rotor draw the air through the rotor to cool it. By keeping the rotor cool it won't transfer as much heat through the pads, caliper, and rest of the braking system. Our kits are designed to fit to the hub without having to remove the hub/bearing.

Since 2010, Advanced Auto Fabrication has been producing and developing both parts and full fledged race cars. Their knowledge base covers a wide range of vehicles both domestic and imported. In the specific case of BMW, the team at AAF has a particular affinity for building and designing components for BMW race cars. Extend the life of your calipers pads and rotors with the AAF E30 Brake Cooling Duct Kit. Brake cooling is a must for BMW’s that see track use. AAF's Backing Plates feature a large “Pocket” to allow for more efficient air flow into the brake hat. This allows air to travel through the vents in the rotor. AAF's Backing Plate is the full size of the rotor and is a heat shield for the shocks and ball joints. The lightweight aluminum tubes provide a sturdy enough passage for air to travel to the rotor, while being able to take some abuse if the tire or road debris comes into contact with it. On very tight turns the tire will contact the aluminum tube and not the flex hose making the flex hose last much longer. The AAF adapter inlet attaches directly to the factory brake duct inlet with no other modifications needed(1987 or newer). Kit Includes: Two 3' Aluminum Duct Tubes One length of Flex tube (you cut to length for each side) Two AAF Backing plates (left & right) Eight hose clamps Attaching hardware AAF Adapter for the factory inlet.

AAF's Backing Plate is the full size of the rotor and is a heat shield for the shocks and ball joints. Heating of your shock oil causes oil thinning, which changes the shock dampening characteristics. Protecting your ball joints from heat will improve longevity and prevent premature wear. The backing plates are powder coated black for extra durability and attractive aesthetics. They replace the OEM dust shields, and will need to be removed before installation.
