If you’re serious about drag racing, you know that every little detail counts—especially when it comes to your brakes. This rear brake system is built specifically for the hardcore drag racer who needs reliable stopping power when launching or staging. We’ve got two S4 4-piston calipers paired with an 11-inch by 1-inch directional, two-piece rotor that’s been slotted and drilled, plus zinc plated for that extra durability. Just a heads-up, this setup is designed for heavy, fast cars, so you’ll want to make sure it fits your rig.

Now, let’s talk fitment. This system is tailored for the Ford 9-inch axle with Torino bearing housing ends, and you’ll need a 2.5-inch standoff. Don’t forget: your axle flange has to be turned down to 5.75 inches for everything to line up properly. And if you’re not sure about your housing ends, shoot us a message or check out the images we’ve provided to identify what you’ve got.

We offer different piston sizes to suit your needs. The larger 1.75-inch pistons deliver maximum clamping force, but they can lead to a longer pedal travel because of the volume they require. For those running in classes like NMRA True Street, the smaller 1.375-inch option has become a favorite since it’s perfect for cars that see limited street use. Just keep in mind, these brakes are really meant for the track. If you decide to take your car out on the street, you’ll want to adjust your brake bias carefully to avoid any surprises.

One more thing: the system comes with high-friction pads that are optimized for drag racing. Just know that they tend to create a bit more dust and noise than your average street pads.
