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 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. Our 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.

**Note: this will only fit late model E30s. (1989-1991)**
