Brake Cooling Backing Plates Aluminum Air Duct for BMW M3 G80 and M4 G82 High-Performance Upgrade
Upgrade your BMW M3 M80? M3 G80 M4 G82 with purpose-built aluminum Brake Cooling Backing Plates from egrtuned. These air ducts channel cool air directly into the rotor hat, maximizing heat transfer across the entire backing plate surface. The result is reduced heat buildup, minimized brake wear, and less pedal fade during spirited driving or track sessions. Built to integrate with OEM mounting points, these lightweight ducts preserve factory fitment while boosting braking efficiency where you need it most.
Designed specifically for the BMW M4 G82 (and compatible with M3 G80), the system uses a durable powder-coated, solid aluminum construction that stands up to road use and the harsh environment under the hood. The setup supports most rotor upgrades, though aftermarket configurations may require minor modifications. For an easy install, the original dust shields should be removed or cut away, and no hub disassembly is required. The kit includes both left and right air duct outlets for a complete upgrade.
Benefits & Tips
- Direct rotor cooling: The large air pockets optimize heat exchange, helping prevent brake fade during repeated high-heat braking.
- OEM-friendly installation: Uses stock mounting points and hardware for a clean, secure retrofit without extensive fabrication.
- Rotor upgrade ready: Compatible with many rotor upgrades; plan for small adjustments if using unconventional rotor setups.
