E9X/E8X brake duct

Unleash Your BMW's True Stopping Power.

Maximize your braking performance with our precision-engineered Brake Duct Kit for the E8X and E9X chassis. Designed to channel cool air directly to your brakes, this kit fights fade, extends pad and rotor life, and ensures consistent performance—lap after lap.

Key Features & Precision Design

• 3D Scanned & 3D Printed Construction: Each duct is designed using a precise 3D scan of the actual arm and wheel housing area, ensuring a perfect, model-specific fit. The ducts are then 3D printed for accuracy and durability, delivering an OEM-quality installation.
• Inspired by Porsche GT3 Engineering: Our design draws inspiration from the legendary Porsche GT3 brake duct. It guides cold air from the undercar high-pressure area directly to the inner part of the brake disc via the OEM brake shield, maximizing cooling efficiency where it matters most.
• Clog-Resistant Design: Unlike other designs that are susceptible to debris getting stuck in them, our duct features a thoughtfully engineered shape that resists clogging from road debris, leaves, and track rubber—keeping airflow consistent without constant maintenance.
• Optional Companion to Our Big Brake Kit: Perfect as a standalone upgrade or paired with our Big Brake Kit for the ultimate track-ready braking setup.
