It’s a fact that the smaller the brakes are, the harder they have to work. Stock 11” brakes benefit greatly from our tried and true cooling kit. This kit is designed to fit the stock or repro four piston, fixed caliper 11” disc brakes (6.9375" OD plates) as found on 1965 to 1967 Ford Mustangs. It works just like our 12” version. Cooling plates finished in a maintenance free, silver high-temperature, thermal barrier coating. Instructions included.
