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 (extending its life) and through the vented cooling vanes of the rotor, which sheds this brake heat out through the rotor like a pump.
Vorshlag's solution involves this stainless steel backing plate that has a 4" oval duct located "under" the rotor face. This backing plate also serves as a heat shield for the two ball joints that make up the lower control arm as well as the steering rack tie rod. 304L stainless material makes for a great heat shield. The face of the rotor is uncovered beyond a tiny radial portion that helps seal the backing plate to the rotor, which maximizes cooling flow where you want it.

Vorshlag has tested this 4" S550 backing plate kit onto their own car with both the 15" PP brakes as well as the Motorsports grade 380x34mm Powerbrake 6 piston kit (see above).
Key Features
- CNC Laser Cut, Stainless Steel Construction
- Tight fit to rotor face to limit air bleeding off the rotor.
- Oval ducting hole is almost completely inside inside rotor hat resulting in more effective cooling.
- Fits inside common 4" brake cooling hose without modification (optional).
- All mounting hardware included
- This product is for 2015-23 Mustang GTs with the OEM 15" 6 piston Brembo front brake option (PP1)
- Also works with Powebrake 380x34mm 6 piston big brake kit
- Brake cooling hose sold separately - see options
- They also make brake INLET duct kits for some S550 models

THIS DOES NOT FIT THE GT350 OR PP2 FRONT SPINDLE!
Brake Ducting Hose: For duct hose Vorshlag only uses the best, this is not some hardware store dryer hose. They use a silicone double wall tubing that allows the best possible air flow and is super durable. This option includes 4 clamps and two 4-foot section of high quality brake duct hose that will properly fit over the Vorshlag Brake Duct Backing Plates.
