This braking system is equipped with 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 designed with D.O.T compliant dust and weather seals, ensuring dependable performance in various conditions. It accommodates the widely used DR1 or HB100 pad type, making replacements a breeze.

You'll appreciate the billet aluminum hubs that come fully assembled with top-notch bearings, all packed with Redline synthetic grease for smooth operation. Plus, the billet dust caps add an extra layer of protection. The rotors are pre-assembled using NAS high-grade stainless hardware, ensuring everything stays securely in place.

We've included all the necessary mounting brackets, stainless braided hoses, and hardware, so you have everything you need right out of the box. The 11" SS4+ system is thoughtfully designed to mirror Baer's larger systems but is compact enough to fit snugly under 15-inch wheels. It's a perfect fit for the 1971-73 Ford Mustang, 70-74 Maverick, 1971-73 Mercury Cougar, and 70-74 Comet with OE Disc Brake Spindle.
