This system boasts an impressive 4-piston S4 caliper, perfectly 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 works seamlessly with the popular DR1 or HB100 pad types. You’ll find that the billet aluminum hubs come fully assembled with top-notch bearings, all packed with Redline synthetic grease, and topped off with sturdy billet dust caps.

Each rotor is pre-assembled using NAS high-grade stainless hardware, ensuring everything is ready to go right out of the box. Plus, all necessary mounting brackets, stainless braided hoses, and hardware are included for your convenience. The 11" SS4+ is crafted just like Baer's larger systems, but designed to fit snugly in 15-inch wheels—perfect for those looking for a compact yet powerful upgrade.

This system is compatible with a variety of classic cars, including the 1965-69 Ford Mustang, 62-69 Fairlane, 63-69 Falcon, 1969 Torino, and the 1967-69 Mercury Cougar, as well as the 66-69 Comet and 1969 Cyclone with OE drum brake spindles.
