If you’re looking to upgrade your classic Ford Mustang’s braking system, the SS4+ rear brake setup is a solid choice. This system features the S4 4-piston caliper, which is mounted to a robust 13-inch two-piece rotor. You’ll appreciate the attention to detail here—these rotors are not just any rotors; they’re slot and drilled, zinc plated for durability. Plus, the stainless steel brake hoses and D.O.T. compliant dust and weather seals on the calipers ensure that you’re getting a reliable performance, rain or shine.

What really stands out is the quality of the components. The bearings are top-notch, and the NAS high-grade stainless hardware means you won’t have to worry about rust or corrosion. The SS4+ is designed to fit snugly within 17-inch wheels, making it a great option for those who want to keep that classic look while still enjoying modern performance. And yes, park brake cables are included, so you won’t be scrambling to find those separately.

Fitment:

• Perfectly designed for 1967-1973 Ford Mustangs with the SHELBY logo and either a 9-inch small bearing or an 8-inch standard bearing rear housing.
• Features a 5 x 4.500-inch wheel bolt pattern, ensuring compatibility with a wide range of wheels.

Why go for the SS4+?

• It packs all the advantages of Baer’s larger brake systems but is tailored for those smaller 17-inch wheels.
• Ideal for anyone wanting to keep their 17-inch wheels or for enthusiasts who might want to switch back to a stock look without sacrificing performance.
• Everything you need is included—hoses, fittings, and park brake cables, so you can get right to the installation.
• The 6061 T-6 billet aluminum hat is anodized black and securely bolted to the rotor, adding both style and strength.
• With high-grade U281 fine thread stainless hardware and captured nuts, you can trust that everything will hold up under stress.

Let’s talk about the S4 Caliper:

• It features four 10mm cross bolts that provide maximum stiffness, which is crucial for performance braking.
• Stainless steel abutments and noise suppression springs help keep things quiet and smooth.
• The hard anodized aluminum pistons are built to last, and the internal crossover design is pretty clever.
• With dual seals—dust/weather and pressure—you know it meets D.O.T. specifications.
• Plus, there’s a machined logo that’s hand-painted, giving it a unique touch.
• It uses a common 4-piston pad for easy replacements, and you can even get it in a red powder coat finish, with custom colors available.
• Everything is made right here in the USA with US-sourced materials, which is something I really appreciate.

So if you’re ready to take your Mustang’s braking to the next level, the Baer Brakes SS4+ system is worth considering. It combines modern performance with classic styling, and it’s built to last.
