This system is designed with the S4 4-piston caliper, perfectly paired with a 12-inch, one-piece slotted and drilled zinc-plated rotor. The S4 caliper is equipped with D.O.T compliant dust and weather seals, ensuring reliability in various conditions. It works seamlessly with the popular DR1 or HB100 pad types, giving you flexibility in performance. What sets Baer's design apart is the innovative backing plate, which not only serves as a caliper mount but also incorporates a modern one-piece park brake shoe assembly. You’ll also find stainless braided hoses included, adding to the durability and efficiency of the system. The 12-inch SS4 is compatible with most 16-inch or larger wheels, making it a versatile choice for your ride. This system fits the 1993 Ford Mustang with an OE Ford 8.8" C-clip rear end and 5 lug configuration.
