If you're looking to upgrade your braking game, let me tell you about this Baer 13" SS4+ Rear Brake Kit. This isn't just any brake kit; it's designed with some serious thought and engineering behind it. With a robust 4-piston S4 caliper, you're getting a solid piece of hardware that’s made right here in Phoenix, AZ. The caliper is mounted to a slick 13" two-piece rotor that’s not just slotted but also drilled and zinc-plated for that extra durability and style.

One of the best parts? The S4 caliper comes with D.O.T compliant dust and weather seals, so you know it can handle whatever Mother Nature throws your way. Plus, it uses the popular DR1-C pad type, which means you’re getting reliable stopping power that’s been proven by folks who know their stuff.

Installation is straightforward, thanks to the pre-assembled rotors that come with high-grade NAS stainless hardware. And let’s not forget about the unique backing plate—this isn’t just a caliper mount; it also houses a modern one-piece park brake shoe assembly. Talk about clever engineering!

What’s cool is that this kit fits most 17" wheels or larger, so if you’ve got the space, you’re good to go. Just make sure your rear end has the Ford 9" Early Big Bearing Housing Ends with a 5x5.00" bolt pattern, and you’re set. I’ve seen it clear 35-inch tires on some builds with just a bit of trimming, which is a nice bonus if you're looking to beef up your stance.
