This braking system is designed with a robust 4-piston S4 caliper, perfectly paired with a 13-inch, two-piece slotted and drilled, zinc-plated rotor. The S4 caliper is equipped with D.O.T compliant dust and weather seals, ensuring durability in various conditions, and it utilizes the widely favored DR1-C pad type. Each rotor comes pre-assembled with high-grade NAS stainless hardware for added reliability.

What sets Baer apart is their innovative backing plate, which not only serves as a caliper mount but also integrates a modern one-piece parking brake shoe assembly. To top it off, stainless braided hoses and hardware are included to enhance the overall performance.

The 13" SS4+ is compatible with most 17-inch or larger wheels, making it a great fit for your ride. Specifically, it’s designed for the 1979-92 Ford Mustang with an OE Ford 8.8" C-clip rear end (4 Lug).
