Vorshlag S550 4" Oval Brake Duct Backing Plates (Pair) for 2015+ Mustang GT PP1

Vorshlag has been setting up many different cars for track use for a very long time. Along the way they have learned a thing or two about the capabilities of OEM braking systems. For their shop S550 chassis, they started with a base model 14" 4 piston brakes. These rotors are built "backwards" and there is no way to push any cooling air through them. So they quickly upgraded to the optional "Performance Pack" 15" 6 piston Brembo brakes.This is the minimum they recommend for these heavy S550 cars, which have a powerful V8 and some serious speed potential. At tracks like NOLA and COTA where you can see 145+ mph speeds into heavy braking zones. That heat has to go somewhere, and that's where brake cooling comes in. They like to take a high pressure stream of air from the front of the car (see optional inlet ducts, shown below), run this air through some ducting or hose, and force it into the back of the front brake rotors. This pushes a high volume of air around the front wheel bearing (e
