This system boasts a 4-piston S4 caliper paired with an 11" two-piece slotted, drilled, and 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 fitted with billet dust caps. The rotors are pre-assembled using NAS high-grade stainless hardware, ensuring durability and reliability.

Included in this package are all the necessary mounting brackets, stainless braided hoses, and hardware, making installation a breeze. The 11" SS4+ is crafted just like Baer's larger systems but is designed to fit perfectly within 15" wheels, providing an impressive performance upgrade without compromising on space.

This system is compatible with 1964-72 GM A-Body, 67-69 F-Body, and 64-74 X-Body cars with OE spindles. It also fits DSE, Heidt's, Fatman, Ridetech, and L&H drop spindles, making it a versatile choice for your classic ride.
