Introducing our impressive braking system, featuring 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, ensuring durability in various conditions. It’s compatible with the widely used DR1 or HB100 pad types, making replacement a breeze.

The rotors come pre-assembled with NAS high-grade stainless hardware, giving you peace of mind with every stop. Our billet aluminum hubs are assembled with premium bearings, all packed with Redline synthetic grease for smooth operation. Plus, they include 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 straightforward. The 11-inch SS4+ is designed just like Baer's larger systems but is compact enough to fit perfectly within 15-inch wheels. This system is a perfect fit for 1978-88 GM G-body vehicles and comes fully assembled on stock height spindles, making it an easy upgrade for your ride!
