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

Clear BMW chassis

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.

Whether it is installing new wider wheels, tires, brake ducts, shocks, or springs, there could be a rubbing issue on the inside of your fender well. Our rack stops will help protect your investment. Rack stops are spacers that install inside of the tie rod and limits the amount of steering travel. You can save the costs of replacing rubbing tires, worn out brake ducts, cut shock reservoir hoses, and broken underside plastic panels. There is also the added benefit of knowing you can turn the steering wheel to full lock and not be worried that the wheels will rub. Our rack stop length is the approximate length that will be removed from the outside tire wall�s path. For example, if a 16mm rack stop is used, there will be 16mm more clearance for a brake duct between the fender well and the edge of the tire. Included with this kit: 2 Delrin rack stops, 1 black (driver�s side), 1 white (passenger�s side), 2 Locking plates (only needed on E36), 4 zip ties, detailed instructions.
