If you're looking to upgrade your ride's stopping power without going overboard, the SS4+ brake system is a solid choice. This setup features a 4-piston S4 caliper paired with an 11-inch two-piece slotted and drilled rotor that's zinc-plated. Trust me, that’s not just for looks; it helps with heat dissipation and keeps things looking sharp. Plus, you get stainless steel brake hoses and calipers that are built to handle the elements with D.O.T. compliant dust and weather seals. It’s all about quality here, with top-notch bearings and NAS high-grade stainless hardware holding everything together.

Now, let’s talk fitment. This system is designed specifically for the 1969-1970 GM full-size cars using stock spindles, and it fits perfectly on the 1969-1970 GM Y-Body as well. So, if you’ve got a Bel Air, Biscayne, Brookwood, Caprice, or Impala from those years, you’re in luck. It’s a great option for enthusiasts who want to keep that classic look while enjoying the benefits of modern braking technology.

What’s cool about the SS4+ is that it packs in all the performance of Baer's larger systems but in a compact package that fits under 15-inch wheels. This means you can upgrade to larger wheels if you want, but you still have the option to revert to the stock look if you ever feel nostalgic. Everything you need comes in the kit—hoses, fittings, the works.

• The hat is made from 6061 T-6 billet aluminum and anodized black, securely bolted to the rotor.
• You’ll find high-grade U281 fine thread stainless hardware with captured nuts, and the rotor comes pre-assembled, which is a nice touch.
• It includes a set of 6061-T6 billet machined hubs, complete with quality bearings and races already installed and packed with Redline synthetic grease.
• And if you’re still running your stock rear drum system, no worries—this setup plays nicely with that.

Now, let’s dive into the S4 caliper features:

• Four 10mm cross bolts for maximum stiffness—this thing is built to last.
• Stainless steel abutments and noise suppression springs keep things quiet.
• Hard anodized aluminum pistons offer durability and performance.
• It has an internal crossover design and dual seals to meet D.O.T. specs.
• Each caliper has a machined logo that’s hand-painted; it’s those little details that matter.
• Common 4-Piston pads (DR1) make replacements a breeze.
• Available in a black powder coat finish, with standard colors like red, black, and silver, plus custom colors if you want to stand out.
• And don’t worry about altering your track width—this system keeps everything right where it should be.
• Best of all, it’s 100% made in the USA with US-sourced materials.

So, if you’re in the market for a reliable brake upgrade that doesn’t compromise on style or performance, the SS4+ is worth checking out. It’s a great way to enhance your ride’s capabilities while keeping that classic vibe alive.
