If you’re looking to upgrade your ride’s stopping power without sacrificing your 17-inch wheels, the SS4+ rear brake system might just be your new best friend. This setup packs a punch with its S4 4-piston calipers, all mounted on a slick 13-inch two-piece rotor that’s been drilled and slotted for optimal performance. Plus, you get that zinc plating, which not only looks great but also helps fight off rust. I’ve been through my fair share of brake systems, and trust me, the quality of the stainless steel brake hoses and the D.O.T. compliant dust and weather seals really make a difference in daily driving conditions.

Now, let’s talk about the nuts and bolts—literally. The SS4+ is crafted with high-grade NAS stainless hardware, ensuring that everything stays securely in place, even under the toughest conditions. The design is compact, making it ideal for those who want a performance upgrade while keeping the classic look of their ride. Just a heads up, though: park brake cables aren’t included, so you’ll need to grab those separately.

So, who’s this system for?

• If you’ve got a 1978-1987 GM G-Body with GM Saginaw 10 Bolt C-Clip Axles, this is your ticket to better braking.
• It’s perfect for those who want to stick with 17-inch wheels but might want to switch to larger ones down the road.
• Everything you need is included in the box—except for those park brake cables, remember?

The rotors are made from 6061 T-6 billet aluminum, anodized in black and bolted to the rotor for extra durability. And the hardware? Top-notch U281 fine thread stainless with captured nuts, so you won’t be chasing down parts later.

What’s so special about the S4 caliper?

• It’s got four 10mm cross bolts for maximum stiffness—no flexing under pressure.
• The stainless steel abutments and noise suppression springs keep things quiet and smooth.
• Hard anodized aluminum pistons are designed to last, and the internal crossover design is a nice touch.
• With dual seals that meet D.O.T. specs, you can drive with confidence, rain or shine.
• And let’s not forget the stylish machined logo that’s hand-painted—because who doesn’t love a little flair?
• It uses a common 4-piston pad (P/N DR1), so replacements are a breeze.
• Available in a silver powder coat finish, but if you’re feeling adventurous, custom colors are an option.
• And yes, it’s 100% made in the USA with materials sourced right here at home.

Here’s a quick fitment rundown for you:

• Buick Regal 1978-1988
• Chevrolet El Camino 1978-1987
• Chevrolet Malibu 1978-1983
• Chevrolet Monte Carlo 1978-1988
