Alright, let’s talk about the SS4+ Deep Stage Drag Race Brake System. If you’re serious about drag racing, you know how critical it is to have a solid braking setup. This rear system is built for the heavy hitters—those fast drag cars that need to launch hard and stage like a pro. It comes with two S4 4-piston calipers paired up with 11 inch x 1 inch directional, 2-piece slotted and drilled rotors that are zinc plated. Trust me, this setup is all about keeping you in control when the lights go green.

Now, before you dive in, a couple of things to note. The rear system is tailored to the housing end you’re using. If you’re scratching your head about what you’ve got, just hit us up or check out the images below to help identify your setup. Oh, and your axle flange? It’s gotta be turned down to 5.75 inches for this system to fit properly.

For those looking for options, we’ve got different piston sizes. The larger 1.75-inch pistons are great for maximum clamping force, but they can lead to long pedal travel since they need more fluid. That’s why we also offer a smaller 1.375-inch piston option, which has been a hit in classes like NMRA True Street where cars see some street use. Just keep in mind, these systems are really meant for racing. If you plan on hitting the streets, you’ll want to adjust your brake bias to make sure everything feels right.

Speaking of brakes, this system comes with high-friction pads designed specifically for drag racing. Just a heads-up, they tend to kick up a bit more dust and noise than your average street pads.
