Alright, let’s talk about the Baer 13" SS4+ Rear Brake Kit. If you own a classic GM full-size passenger car from '71 to '76, this upgrade is something worth considering. I’ve had my hands on this kit, and it’s clear that Baer knows what they’re doing. You’re getting a robust 4-piston S4 caliper that’s not just thrown together; it’s precision-engineered right in Phoenix, AZ. The caliper is CNC machined from high-quality forged or billet aluminum, so you know it’s built to last.

The rotors? They’re a solid 13 inches and come as a 2-piece design, which means they’re lighter and easier to manage than traditional solid rotors. Plus, they’re slotted and drilled, which helps with heat dissipation and keeps things cool under pressure. The zinc-plated finish adds a nice touch too, protecting against rust and wear. You’ll also appreciate the NAS high-grade stainless hardware that comes pre-assembled with the rotors—it’s all about durability here.

One of the standout features is the unique backing plate that not only mounts the caliper but also houses a modern 1-piece park brake shoe assembly. This integration simplifies installation and keeps everything neat and tidy. And let’s not forget the stainless braided hoses included in the kit—these add strength and flexibility, which is crucial for performance braking.

Now, if you’re concerned about fitment, this kit is designed to fit most 17-inch wheels and larger, making it a versatile choice for your ride. Just make sure your axle has the OE large pattern 10/12 bolt bearing on the axle housing ends, and you’re good to go. The caliper comes in a sleek black finish, and with its hard anodized aluminum pistons and dual seals for dust and weather protection, you’re set for whatever the road throws at you.

To sum it up, if you’re looking to upgrade your braking system, the Baer 13" SS4+ kit is a performance-oriented choice that doesn’t skimp on quality. It’s got the specs to back it up, and trust me, once you hit the road with this setup, you’ll feel the difference. Whether you’re cruising or hitting the track, this kit is ready to deliver.
