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.

Race German has devoted themselves to providing quality products for late model BMWs that cover both street and track applications. Race German has now grown their catalog to a wide variety of models and products geared towards keeping your car looking and running nice. Cooling your brakes is essential for high endurance racing, or track days. Your brakes tend to fade after a 15 minute session on track, so Race German has developed a way to cool them. The late model E30 bumper already has inlets for brake cooling, but an adapter is needed to convert the square outlet to a 3" outlet for common brake ducting. These E30 brake duct inlet adapters are CAD designed and 3D printed here in the USA. They perfectly fit around the OEM E30 inlet duct and convert to the 3" outlet you need. There are holes printed in the ducts to secure them with provided zip ties so they do not fall out. **3D printed parts can have minor imperfections.

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. These Backing Plates by Advanced Auto Fabrication 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. 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.

In the specific case of BMW, the team at AAF has a particular affinity for building and designing components for BMW race cars. AAF is proud to introduce their redesigned AAF E46 (non-M) Brake Cooling Duct Kit! Features: Extremely Light Weight – Less than 4 lbs in total! Ultra-High Airflow Inlets Tight Turning Radius Easy and Quick To Install Inexpensive to Buy and Maintain Durable for Racing Conditions Designed strong and lightweight these brake duct inlets include a massive 4' inlet. Ultimately this aids in providing higher airspeed and pressure to the brake rotor and thus better brake cooling. Inlets are manufactured by AAF in-house with a 3D printer to provide a strong and inexpensive part. Brake duct tubes included in this kit are made from lightweight and strong ABS plastic. Shaped for optimized airflow, these tubes also provide the ability for a tight turning radius even with large racing tires. Per AAF: for a SPEC E46 with the spec 255 Toyo tire, you can turn 1.5 turns from straight without hitting the tubes, which is more than enough for driving around the paddock. The tubes taper down to a 3' flex hose, to remain legal for SE46. Included in the kit are AAF's Brake Backing Plates as well. Kit Contents: Left and Right AAF 3D Printed Massive 4' Inlets Left and Right 4' to 3' Molded Tubes Two 13' Sections of Flex Hose Left and Right AAF Backing Plates All Attaching Hardware and Hose Clamps

This is AutoTecknic's newly developed dry carbon fiber competition brake air ducts for the F82 and F83 M4. Similar to the brake air ducts found on the factory GT4 race car, it's designed to mount directly onto the front bumper. Dry carbon fiber's name comes from its manufacturing process. Dry carbon fiber is formed by using a "pre-preg" or impregnated piece of carbon materials. This piece of carbon is first placed into a mold, and then into a sealed autoclave to properly cure. This particular method creates the least amount of waste and forms a lighter version of carbon than the “wet” method. The autoclave vacuuming process of making dry carbon means that there are fewer pinholes and virtually no air pockets that form in the carbon. Dry carbon is the highest-quality version of carbon fiber products that are produced. Note: Modification is required to the bumper prior to installation.

In the specific case of BMW, the team at AAF has a particular affinity for building and designing components for BMW race cars. AAF's brake duct adapters slide directly over the OEM e30 brake duct inlets. They suggest using a strong 2 part bonding adhesive to attach the duct adapters to the OEM brake duct inlet. This is ideal for maximum airflow, as it does not intrude into the air duct, and will create an air-tight seal around the joint. These are the perfect answer for your brake duct kit.

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.
