If you’re looking to upgrade your ride's stopping power without sacrificing that classic vibe, the SS4+ brake system is right up your alley. This setup packs a punch with its S4 4-piston calipers, all mounted on an 11-inch two-piece rotor that’s not only slotted and drilled but also zinc plated for durability. One thing I really appreciate about Baer is their attention to detail—these calipers come with D.O.T. compliant dust and weather seals, so you know they’re built to withstand the elements. Plus, the stainless steel brake hoses are a nice touch, ensuring everything stays tight and reliable over time.

Now, let’s talk fitment. This system is designed specifically for the 1969-1970 GM Fullsize cars with stock spindles, and it also fits the 1969-1970 GM Y-Body stock spindles. So, if you’re rocking one of those classics, you’re in luck.

Why go for the SS4+? Well, it’s like getting all the benefits of Baer’s larger brake systems but in a compact package that fits your 15-inch wheels. It’s perfect for those of us who want a beefier setup while still keeping that stock look if we ever decide to switch back. Everything you need comes in the box—hoses, fittings, the whole nine yards.

And let’s not forget about the construction. The hat is made from 6061 T-6 billet aluminum, anodized black, and securely bolted to the rotor. You’ll also find high-grade U281 fine thread stainless hardware with captured nuts, and the rotor comes pre-assembled, which is a huge time-saver. The hubs are another highlight—6061-T6 billet machined with quality bearings and races already installed, packed with Redline synthetic grease. It’s a solid setup that you can trust.

As for the S4 caliper itself, it’s got some serious engineering behind it. There are four 10mm cross bolts for maximum stiffness, stainless steel abutments, and noise suppression springs to keep things quiet. The hard anodized aluminum pistons and internal crossover design ensure smooth operation, while the dual seals meet D.O.T. specs for dust, weather, and pressure. Plus, the machined logo is hand-painted, which adds a nice touch of craftsmanship.

When it comes to maintenance, you’ll appreciate that it uses a common 4-piston pad for easy replacements (the DR1 pads fit right in). The silver powder coat finish is standard in red, black, or silver, but if you’re feeling adventurous, custom colors are available. And if you want that uniform look, these calipers are available for both front and rear installations.

Best of all, there are no changes to your track width, so you won’t have to worry about any fitment issues. And let’s not overlook the fact that this setup is 100% made in the USA with materials sourced right here at home.

In short, if you’re driving a 1969-1970 Chevrolet Bel Air, Biscayne, Brookwood, Caprice, Corvette, or Impala, the SS4+ is a fantastic upgrade that combines performance and style without losing that classic charm.
