If you're looking to upgrade your Mustang's braking system without sacrificing that classic look, the SS4+ is definitely worth a closer look. This rear brake system packs a punch with its S4 4-piston caliper, which is mounted to a solid 13-inch, two-piece rotor that's been slot and drilled for better heat dissipation. Trust me, this setup gives you the stopping power you need, especially when you're pushing your Mustang to its limits. Plus, the zinc plating on the rotor helps keep things rust-free, so you can hit the road with confidence.

One of the things I really appreciate about the SS4+ is the attention to detail. Baer has included stainless steel brake hoses that are built to last, and the calipers come with D.O.T. compliant dust and weather seals. It’s all about keeping the grit and grime out, right? And let’s not forget about the quality bearings and NAS high-grade stainless hardware that come with the pre-assembled rotor. It’s all designed to make your life easier and your ride smoother.

This system is tailored for those of us who are rolling with 17-inch wheels. It’s like Baer took the features of their larger systems and condensed them into a package that fits perfectly without compromising on performance. Plus, if you ever want to switch back to a stock look, this setup gives you that flexibility.

Fitment:

• Designed for 1967-1973 Ford Mustang 9 Inch Small Bearing and 8 Inch Standard Bearing Rear Housings.

Why consider the SS4+?
