If you're looking to give your Mustang a serious upgrade, the SS4+ Deep Stage Drag Race System is where it's at. This isn't just any brake system—it's built for those of us who love pushing our heavy, fast cars to the limit, whether at the strip or cruising down the street. With a slick 4-piston caliper nestled against an 11-inch, 2-piece slotted and drilled rotor, you're getting some serious stopping power here. And let’s be real, when you're going fast, you want to know you can stop just as quickly.

One of the standout features is the D.O.T. compliant dust and weather seals on the calipers. This means you can count on them to perform, rain or shine. Plus, the quality bearings and high-grade NAS stainless hardware make this setup not just tough but reliable too. What’s cool is that the SS4+ is designed to fit snugly behind 15-inch wheels, so you don’t have to compromise on style or performance.

The rotors are vented, which helps with heat dissipation during those intense runs. And the hubs? They come equipped with ARP 1/2 inch x 20 race studs—because when you’re pushing the pedal to the metal, you want everything to stay firmly in place.

Fitment:

• Perfectly designed for 1979-1993 Ford Mustang 4-Lug Wheels without SN95 spindles and hubs.

Why should you consider the SS4+ Deep Stage Drag Race System?

• It packs all the benefits of Baer’s larger brake systems into a smaller package, tailored for 15-inch wheels.
• Built for heavy, fast cars but still street-friendly—so you can enjoy the best of both worlds.
• The hat is made from 6061 T-6 billet aluminum, anodized black, and securely bolted to the rotor.
• High-grade U281 fine thread stainless hardware with captured nuts means it’s easy to install, and the rotor comes pre-assembled.
• Includes 6061-T6 billet machined hubs with Timken or SKF bearings and races already installed.
• Hubs are pre-assembled with everything you need—bearings, races, studs, and even packed with Redline synthetic grease.
• Comes with ARP 1/2 Inch x 20 race studs for that extra edge.

Here’s what makes the S4 caliper special:

• Four 10mm cross bolts for maximum stiffness—because rigidity is key when you’re racing.
• Stainless steel abutments and noise suppression springs keep things quiet and smooth.
• Hard anodized aluminum pistons for durability and performance.
• Internal crossover design helps with consistent pressure across the caliper.
• Dual seals that meet D.O.T. specs—dust, weather, and pressure resistant.
• Each caliper features a machined logo that's hand-painted, adding a personal touch.
• Uses a common 4-piston pad for easy replacements—P/N DR1, so you won’t be scrambling to find parts.
• Clear powder coat finish is standard, with options like Fire Red and custom colors available.
• Available for both front and rear, so you can keep that aesthetic consistent.
• Uses correct banjo-style fittings—no pipe threads here, just solid engineering.
• And best of all, it's 100% made in the USA with materials sourced right here at home!
