These competition multi piece cooling plates are designed for the absolute maximum cooling effect to our 12” disc brake rotors. Intricately made in two pieces to fit our big spindles like the proverbial glove, these cooling plates also feature a special lip around the outer circumference for a complete 360 degree seal to the rotor. These plates were developed on our own in-house No. 530 competition car as part of our ongoing efforts to provide the finest components possible for the vintage racing Mustang. Finished in a maintenance free, silver high-temperature thermal barrier coating.
