BMW Brake Cooling Ducts & Backing Plates for BMW 3 Series E30 (1984-1991)

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.

These allow you to duct fresh, cool air to the center of the rotor where it needs it most. The addition of these backing plates and appropriate ducting will increase brake pad life by as much as 50%! A cooler braking system will also dramatically reduce brake fade and decrease braking distances.

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.
