If you're looking to upgrade your ride's stopping power, the Baer 13" SS4+ Rear Brake Kit is a solid choice, especially for those classic GM F-Body cars from '67 to '69. This kit isn’t just about looks; it’s built to perform. The heart of the system is the 4-piston S4 caliper, which is mounted to a beefy 13-inch, 2-piece slotted and drilled rotor that’s zinc-plated for durability. You can really feel the difference when you hit the brakes hard—this setup gives you confidence on the road.

What I love about the S4 caliper is that it’s got D.O.T compliant dust and weather seals. So, whether you're cruising through rain or kicking up dust on a backroad, these calipers are ready to handle it. Plus, they use the DR1-C pad type, which is pretty popular, making replacements easy to find. And let’s talk about the rotors—they come pre-assembled with high-grade stainless hardware, so you know you’re getting quality right out of the box.

One feature that stands out is Baer's unique backing plate. It not only serves as a caliper mount but also houses a modern one-piece park brake shoe assembly. This means you get a cleaner installation and reliable performance. The included stainless braided hoses are a nice touch, too; they add to the overall durability and responsiveness of the braking system.

Now, if you’re running 17-inch wheels or larger, you’re in luck because this setup fits perfectly. The 13" SS4+ is designed to work with most 17" or larger wheels, so you don’t have to worry about compatibility issues. Just make sure you’ve got the right axle setup—this kit fits the OE small pattern 10/12 bolt bearing on axle housing ends and also works with the hybrid 10/12 bolt non-flush mount 3.150" bearing.
