Competition Dual Duct Rear Drum Brake Cooling Kit

When even more cooling is required for the rear drum brakes on a maximum effort, for a Mustang vintage race car this upgraded kit is the answer.  Dual ducts feeding air into two 3” hose adapters on each backing plate yield an immediately noticeable increase in cooling effectiveness.  We have seen less pad wear and reduced fade every time this upgrade has been installed on one of our vintage race cars.  As with the standard kit there is no ground clearance issue because the air scoops move up and down with the suspension.  Twice as many holes will need to be drilled in the backing plate for cooling and adapter flange mounting but it will be worth the effort.  One size fits both 10” and 11” backing plates.
