This system showcases a robust 4-piston S4 caliper paired with an 11" two-piece slotted and drilled rotor, beautifully zinc plated for durability. The S4 caliper is designed with D.O.T compliant dust and weather seals, and it’s compatible with the popular DR1 or HB100 pad types. You’ll find that the rotors come pre-assembled with high-grade NAS stainless hardware, ensuring top-notch quality.

Each billet aluminum hub is thoughtfully assembled with premium bearings, all packed with Redline synthetic grease for smooth performance. Plus, they come with billet dust caps and are pre-assembled on stock height spindles for your convenience. We’ve also included all the necessary mounting brackets, stainless braided hoses, and hardware to make installation a breeze.

The 11" SS4+ system is designed just like Baer's larger offerings but is compact enough to fit perfectly with 15" wheels. It’s compatible with 1973-77 GM A-Body, 70-81 F-Body, and 75-79 X-Body cars, and arrives fully assembled on stock height spindles.
