If you’re looking to amp up your Mustang’s stopping power, the Extreme+ system is worth checking out. This setup features a solid 1-piece Monoblock 6-piston caliper that’s not just any caliper; it’s a 6S model, crafted right in Phoenix, AZ from high-quality 2618 Aluminum. You can feel the difference in weight and performance when you hit the brakes. The stainless steel pistons and abutments are built to last, and those D.O.T. compliant dust and weather seals ensure that dirt and grime won’t mess with your performance.

Now, let’s talk about the rotors. You’re getting a 15-inch, 2-piece slot and drilled rotor that’s zinc plated for extra durability. These rotors come pre-assembled with some high-grade stainless hardware, so you know they’re built to handle whatever you throw at them. Plus, Baer’s unique backing plate doubles as a caliper mount and houses a slick 1-piece park brake shoe assembly. It’s a neat little feature that keeps everything tidy.

This kit is designed to fit most wheels that are 19 inches or larger, so if you’ve got some aftermarket rims, you’re in luck. Just a heads up, it’s compatible with the 2015-2023 Ford Mustang (S550), but won’t fit the GT350, so keep that in mind.
