If you're serious about drag racing, you know how crucial it is to have a reliable braking system. This rear brake setup is built specifically for that purpose. We’re talking about four S4 4-piston calipers paired with 11-inch, 2-piece rotors that are drilled and zinc plated. It’s all about performance here, designed for those heavy hitters that need to get off the line fast. Just a heads-up, this system is tailored for specific housing ends—if you’re not sure what you have, shoot us a message or check out the images below to get it sorted.

Important Note: You’ll need to turn down your axle flange to 5.75 inches for this system to fit correctly. There are different piston sizes available, too. The larger 1.75-inch pistons give you maximum clamping force, but they can lead to a long pedal feel because of the volume they require. On the flip side, the smaller 1.375-inch pistons have been a hit in classes like NMRA True Street, especially for cars that see some limited street action. Just remember, this setup is all about racing. If you decide to hit the streets, you’ll want to adjust your brake bias carefully to avoid any surprises.

• Works with GM 10 Bolt and 12 Bolt axles that have Ford 3.150-inch bearing ends.
