If you're serious about your Mustang and want to take your drag racing game to the next level, the SS4+ Deep Stage Drag Race System is worth a look. This setup is all about performance packed into a compact design that fits right under your 15-inch wheels. With its S4 4-piston caliper paired with an 11-inch two-piece slotted and drilled rotor, you get serious stopping power without the bulk. These rotors are zinc plated, which means they’ll hold up against the elements, and the whole system is designed with D.O.T. compliant dust and weather seals to keep everything running smoothly, no matter where you take it.

One of the standout features here is the high-grade stainless hardware that comes pre-assembled with the rotor. It's the kind of quality you can trust, especially when you're pushing your car hard on the strip or even just cruising around town. And let’s not forget about the design—this system is built for heavy, fast cars, but it’s street-friendly too. It’s like Baer took everything they know about their larger systems and shrunk it down without sacrificing any of the performance.

Now, a heads-up: this kit is designed to work with 1994-2002 Ford Mustang SN95 spindles and hubs, but those aren’t included, so keep that in mind. You might need to turn down your hub to 5.750 inches for the rotor to fit properly, and if you’re using stock outer tie rods, you may run into some interference with the rotor. A quick fix is to grab some aftermarket units like the Baer Adjustable Trackers.

So, why should you consider the SS4+? For starters, it gives you all the advantages of Baer’s larger brake systems but in a smaller package. The 6061 T-6 billet aluminum hat is anodized black and securely bolted to the rotor, ensuring everything stays put under pressure. Plus, the high-grade U281 fine thread stainless hardware with captured nuts means you won’t be fumbling around when it’s time for maintenance. Just a note, brake hoses aren’t included, so you’ll need to pick those up separately.

The S4 caliper is where the magic happens. It features four 10mm cross bolts for maximum stiffness, stainless steel abutments, and noise suppression springs to keep things quiet. The hard anodized aluminum pistons and internal crossover design ensure efficient performance, while the dual seals meet D.O.T. specifications for dust, weather, and pressure. And for those who appreciate a bit of flair, the calipers come in a striking Fire Red powder coat finish, with custom colors available if you want to personalize your setup.

In short, if you’re looking to upgrade your Mustang’s braking system, the SS4+ Deep Stage Drag Race System is a solid choice. It’s built in the USA with US-sourced materials, and it’s designed to deliver serious performance on the track and the street. Whether you’re racing or just enjoying a weekend drive, this system has got you covered.
