This system showcases a robust 4-piston S4 caliper paired with an 11-inch, two-piece slotted and drilled rotor that’s zinc plated for durability. 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 find billet aluminum hubs that come fully assembled with top-notch bearings, all packed with Redline synthetic grease, plus sturdy billet dust caps to keep everything secure.

The rotors are pre-assembled with NAS high-grade stainless hardware, ensuring everything fits together perfectly. We’ve included all the necessary mounting brackets, stainless braided hoses, and hardware you’ll need for a seamless installation. The 11" SS4+ is crafted just like Baer's larger systems but is designed to fit snugly in 15-inch wheels, making it a fantastic option for your ride.

This setup is specifically designed for the 1970-72 Mopar E-Body (Challenger/Barracuda) with the OE 2-Piston Disc Brake Spindle.
