This braking system showcases a robust 4-piston S4 caliper paired with an 11-inch, two-piece slotted and drilled zinc-plated rotor. The S4 caliper is equipped with D.O.T compliant dust and weather seals, and it’s compatible with the widely-used DR1 or HB100 pad types. You’ll love the billet aluminum hubs, which come fully assembled with top-notch bearings packed with Redline synthetic grease, along with durable billet dust caps.

The rotors are pre-assembled using NAS high-grade stainless hardware, ensuring long-lasting performance. You’ll find that all necessary mounting brackets, stainless braided hoses, and hardware are included in the package. The 11” SS4+ is designed similarly to Baer’s larger systems but is compact enough to fit perfectly within 15-inch wheels.

This system is a great fit for the 1970 Ford Mustang, 70-71 Fairlane, 70-71 Torino, and the 1970 Mercury Cougar, along with the 70-71 Cyclone and 70-71 Montego, provided you have the original disc brake spindles.
