If you're looking to upgrade your Mustang's braking game, this rear system from Baer might just be what you need. It features a 6S 6-piston caliper paired with a 14-inch 2-piece slotted and drilled rotor, all zinc plated for durability. One of the standout aspects of this setup is the billet backing plate. Not only does it securely mount the caliper, but it also houses a bankisa 1-piece park shoe. This is a more modern take on parking brakes compared to the usual drum-in-hat systems you see around. Trust me, it works way better.

When it comes to the nitty-gritty, you get stainless steel brake hoses and calipers that are equipped with D.O.T. compliant dust and weather seals, so you know they can handle whatever the road throws at them. The hardware is top-notch too—made of NAS high-grade stainless steel, it’s designed to last. And the rotors? They come pre-assembled, which is a nice touch if you’re doing the work yourself.

The 6S and 6R R-Spec calipers are Baer's pride and joy, crafted from a single piece of US-sourced 2618 forged aluminum. This is a General Fit rear system, so keep in mind it doesn’t come with park brake cables, but everything else you need is included.
