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 we need a way to cool them. The E36 M3 has OEM ducting but does not fit up to common 3" brake duct hose. Our E36 brake duct inlet adapters are CAD designed and 3D printed here in the USA. They perfectly fit around the OEM E36 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.
