If you're serious about drag racing, you know that every little detail counts—especially when it comes to your braking system. This rear brake setup is built specifically for drag racing, featuring two S4 4-piston calipers that grip onto 11-inch x 1-inch directional rotors. These rotors are not just any rotors; they’re two-piece, drilled, and zinc plated, designed to handle the heavy demands of fast cars on the strip. Just a heads up: this system doesn’t come with a park brake, so it’s strictly for those who are all about speed and performance.

Now, let’s talk fitment. This setup is tailored for the 2015 Ford Mustang rear housing, so if you're working with a different setup, give us a shout. One important detail to keep in mind is that your axle flange needs to be turned down to 5.75 inches for this system to fit properly. And if you’re unsure about the housing ends you have, we’re here to help.

When it comes to piston sizes, you’ve got options. The larger 1.75-inch piston is all about maximum clamping force, but it might give you a long pedal feel due to its volume requirements. If you’re looking for something with a bit more finesse, the 1.375-inch piston has been a hit in classes like NMRA True Street, where some street use is allowed. Just remember, these systems are designed for racing, and if you take them on the street, you’ll want to adjust for any brake bias changes.

Speaking of performance, this system comes with high-friction pads that are optimized for drag racing. Expect a bit more dust and noise, but that’s just part of the game when you’re pushing for those quick times.
