If you're looking to take your heavy, fast car to the next level, the 11" SS4+ Deep Stage Rear Brake Kit from Baer Brakes is worth a serious look. This isn’t just any brake system; it’s been specifically designed for those of us who want to push our rides to the limit, whether on the drag strip or the street. Trust me, I've had my hands on this kit, and it’s built for performance.

At the heart of this system are the 4-piston S4 calipers, which are mounted to a robust 11-inch, 2-piece rotor that’s slotted and drilled. This setup not only looks great but also helps with heat dissipation, which is crucial when you're laying down some serious rubber. The calipers feature D.O.T compliant dust and weather seals, so you don’t have to worry about debris messing with your braking performance. Plus, they use the popular DR1 or HB100 pad types, making replacements easy and accessible.

What sets the S4 Deep Stage caliper apart is its 1.75-inch pistons, which deliver extra clamping force compared to the standard S4 calipers. This means you get a more aggressive bite, which is great for drag racing, but if you plan to use these on the street, just be aware that you might need to adjust your brake bias for optimal performance.

The rotors come pre-assembled with NAS high-grade stainless hardware, and the included mounting brackets and hardware make installation a breeze. This system is compatible with most 15-inch wheels, so you won’t have to swap out your rims just to accommodate your new brakes. Just a heads up, though—this kit is primarily designed for racing. If you do plan to use it on the street, take the time to ensure everything is dialed in correctly.

Just know that it comes with a street compound pad that’s quiet and low-dust, but if you’re hitting the track, you’ll want to swap those out for something more aggressive. Overall, it’s a well-thought-out kit that I’d recommend to anyone serious about their performance.
