If you're looking to upgrade your ride’s stopping power, the Baer SS4 rear brake system is worth a serious look. This setup features a robust S4 4-piston caliper paired with a slick 12-inch, one-piece rotor that’s not just drilled and slotted for show—it's designed for performance. I’ve had the chance to put this system through its paces, and let me tell you, it doesn’t disappoint.

One of the standout features is the billet backing plate. It’s more than just a pretty face; it doubles as a caliper mount and houses the Banksia one-piece park brake assembly. This is a game-changer compared to the usual drum-in-hat setups. Trust me, this modern design works way better and feels more reliable. Just keep in mind that this is a General Fit kit, so you’ll need to grab your park brake cables separately.

Now, about the fitment—this kit is designed specifically for an 8.800-inch Ford rear housing with a 2.5-inch standoff, and it comes with a 4 x 4.250 wheel bolt pattern. If you’re running 15-inch wheels, those 12-inch rotors will fit just fine, but it’s a good idea to check with a template to be sure.

So, why should you consider the SS4? For starters, the one-piece, directionally vaned rotor is a perfect match for Baer’s Track4 front brake system, creating a seamless look and feel across your vehicle. The fully machined billet backing plate isn’t just tough; it also holds the Banksia park brake assembly, which utilizes the same shoes as the late-model Corvette C5/C6. That’s some serious pedigree right there.

Each kit comes complete with all the hoses, fittings, and hardware you’ll need to get everything installed without a hassle. Plus, the S4 caliper is built to last, featuring four 10mm cross bolts for maximum stiffness, stainless steel abutments, and noise suppression springs. The hard-anodized aluminum pistons and internal crossover design ensure durability and performance that meets D.O.T. specifications.

And let’s not forget about the aesthetics. The calipers come in a standard silver powder coat finish, with options for red or black, and if you’re feeling adventurous, you can even go for custom colors. Whether you want them for the front or rear, you can achieve that matching look that’s all about style and performance.

Oh, and did I mention that everything is 100% made in the USA? You can feel good about supporting local manufacturing while upgrading your ride. If you’re serious about your brakes, the Baer SS4 is a solid choice that combines modern technology with real-world performance.
