If you're looking to upgrade your braking system without sacrificing your 17-inch wheels, the SS4+ is a solid choice. This rear brake setup features Baer's 4-piston S4 caliper, which is mounted to a 13-inch 2-piece rotor that's not only slotted and drilled but also zinc plated for durability. The quality here is evident; you’ve got stainless steel brake hoses and calipers that come with D.O.T. compliant dust and weather seals, so you know they’re built to last.

One of the standout features is the pre-assembled rotor, which uses high-grade NAS stainless hardware. This means you're not just getting a good-looking system; you're getting something that performs and holds up under pressure. Plus, the SS4+ is designed to fit right into your 1971-1976 GM Full Size Car with either a stock GM 10 Bolt or 12 Bolt rear end. And yes, the park brake cables are included, so you don’t have to hunt for those separately.

• Perfect for those who want to keep their 17-inch wheels or for enthusiasts who might want to swap to larger wheels while still having the option to revert back to stock.
• Everything you need is in the box—hoses, fittings, and cables included.
• The hat is made from 6061 T-6 billet aluminum, anodized black, and securely bolted to the rotor for a clean look and solid performance.
• High-grade U281 fine thread stainless hardware with captured nuts ensures that everything stays tight.

Now, let’s talk about the S4 caliper itself. It’s designed with four 10mm cross bolts for maximum stiffness, and the stainless steel abutments plus noise suppression springs help keep things quiet while you’re on the road. The pistons are hard anodized aluminum, and the internal crossover design is pretty slick. You’ve got dual seals—dust, weather, and pressure—so you can trust that these calipers will hold up to the elements.

• Each caliper features a machined logo that’s hand-painted—details matter, right?
• It uses a common 4-piston pad for easy replacements, specifically the P/N DR1.
• And if black isn’t your color, custom powder coat options are available.
• Available for both front and rear, so you can keep that matching look across your setup.
• Baer sticks to the right fittings; no pipe thread nonsense here, just proper banjo style fittings.
• And here’s the best part—this system is 100% made in the USA with materials sourced right here.

In short, if you’re rolling a '71-'76 Chevrolet Caprice or Impala, this SS4+ brake system is designed to give you all the benefits of bigger brake setups while fitting your smaller wheels. It's a smart move for anyone wanting to enhance their ride without going overboard.
