Features and Benefits:
- Stamped steel construction
- Weld-thru primer finish
- Reduces overall prep time
- Allows rear brakes to cool down

These Brake Ducts allow your rear brakes to cool down while driving your Mustang hard at the track or auto cross. They are made from a stamped steel construction. They also come with a weld-thru primer finish. This helps to reduce preparation time overall. They are specifically made for 1967-1968 Fastback Mustangs. Dyancorn recommends you to get the brake ducts professional installed.

Advantages of Weld-Thru Primer:
- Eliminates corrosion that would form between overlapped panels or multi-layered spot welds
- Helps prevent resin build up between welds that can trap moisture in the old porous steel that leads to failure at the weld borders
- Helps when welding a new panel to old metal
- Lower distortion of the panels
- Lower resistance at the weld surface allows better penetration into the denser, new steel that helps forgive an old alloy's problems with porosity and impurities
- Reduced spatter
- Reduces prep time when welding new parts to new parts that are both covered in the weld thru primer
- Superior conductive properties that help minimize high heat zone problems
