If you're looking to upgrade your '93 Mustang's braking without going overboard, the SS4+ rear brake system might just be what you need. This setup comes with a robust 4-piston S4 caliper paired with a 13-inch 2-piece rotor that's been slotted and drilled for better heat dissipation. You’ll appreciate the zinc plating, which helps keep things rust-free, and the stainless steel brake hoses that are tough enough to handle the elements. Plus, the calipers feature D.O.T. compliant dust and weather seals, so they’ll hold up well in various conditions.

Now, let’s talk about the nitty-gritty. This kit is specifically designed for the 1993 Ford Mustang with an 8.800 Ford C-Clip rear. It fits right in with the 5 x 4.500 inch wheel bolt pattern, making it a straightforward swap for your existing setup. If you’re running 17-inch wheels, you’ll be pleased to know that this system is designed to fit perfectly without compromising performance.

What’s great about the SS4+ is that you get all the benefits of Baer’s larger systems but in a more compact design. It’s perfect for those who want to keep their 17-inch wheels or for enthusiasts who might want to switch it up with larger wheels later on without losing that stock look. The kit includes everything you need—hoses, fittings, and even park brake cables, so you won’t be scrambling for parts when it’s time to install.

Let’s not forget the quality materials. The rotor hat is made from 6061 T-6 billet aluminum, anodized black and securely bolted to the rotor. You’re also getting high-grade U281 fine thread stainless hardware with captured nuts, which means you won't have to worry about rust or wear over time.

Here’s what you can expect from the S4 caliper:

• Four 10mm cross bolts for maximum stiffness—no flexing here.
• Stainless steel abutments and noise suppression springs to keep things quiet.
• Hard anodized aluminum pistons that won’t let you down.
• An internal crossover design that helps with fluid flow.
• Dual seals that meet D.O.T. specs for dust, weather, and pressure.
• A machined logo that’s hand-painted for a touch of class.
• Uses a common 4-piston pad for easy replacements (P/N DR1).
• Comes in a stylish silver powder coat finish, with custom colors available if you want to stand out.
• Available for both front and rear, so you can match that look across your ride.
• Uses the correct banjo-style fittings—no pipe threads here, just solid engineering.
• And best of all, it’s 100% MADE IN USA with US-sourced materials.

So, if you’re ready to step up your Mustang's braking game, the SS4+ is a solid choice. It’s built tough, easy to install, and designed to keep you safe on the road while looking good doing it.
