This braking system showcases a robust 4-piston S4 caliper, perfectly paired with an 11-inch, two-piece slotted and drilled rotor that’s zinc plated for added durability. The S4 caliper is equipped with D.O.T compliant dust and weather seals, and it accommodates the widely used DR1 or HB100 pad type for reliable performance.

With billet aluminum hubs already assembled, you’ll find premium bearings packed with Redline synthetic grease, along with sturdy billet dust caps. The rotors come pre-assembled using high-grade NAS stainless hardware, ensuring everything is ready to go right out of the box. Plus, all necessary mounting brackets and hardware are included for your convenience.

The 11" SS4+ is crafted just like Baer's larger systems, but in a compact size that fits perfectly within 15-inch wheels. It’s designed to fit Ford Mustang II Spindles, and it’s also compatible with Heidts Mustang II Spindles. Get ready to enjoy a powerful upgrade!
