If you're looking to upgrade your Mustang's rear brakes, let me tell you about this Baer Extreme+ system. It's got a solid 6-piston caliper that’s mounted on a beefy 14-inch two-piece rotor—yep, it’s slot and drill, and zinc plated for that extra durability. One of the coolest features is the billet backing plate. Not only does it serve as a caliper mount, but it also houses a modern park brake assembly that works way better than those old-school drum-in-hat setups. Trust me, you’ll appreciate the difference when you hit the brakes.

Now, let’s talk about the build quality. The stainless steel brake hoses are a must for any serious setup, and the calipers come with D.O.T. compliant dust and weather seals. You won't have to worry about rust or grime messing with your performance. Plus, the pre-assembled rotor uses high-grade NAS stainless hardware, which is just a fancy way of saying it’s built to last.

The 6S and 6R R-Spec calipers are Baer's pride and joy. They’re forged from a single piece of 2618 aluminum sourced right here in the USA. It's tough stuff. And if you're into aesthetics, you’ll love how this system gives you that uniform look across the front and rear—Baer is the only brake company doing this. Just make sure your wheels are at least 18 inches; you’ll need to check with the provided template to ensure everything fits snugly.
