If you're looking to upgrade your braking system without sacrificing that classic look, the SS4+ from Baer is a solid choice. This front brake system comes with a robust S4 4-piston caliper, paired with an 11-inch two-piece rotor that’s both slotted and drilled, plus it’s got a zinc plating for added durability. One of the standout features is the D.O.T. compliant dust and weather seals on the calipers, which means they're built to handle whatever the road throws at you. Trust me, those seals make a difference when you're out there pushing your ride to its limits.

Now, if you’re rolling with a 1974-1978 Ford Mustang II spindle or even Heidts Mustang II spindles, you’re in luck. This system is designed to fit right in, making it an easy upgrade for those of us who want better stopping power without going overboard.

What I really appreciate about the SS4+ is that you get all the benefits of Baer’s larger brake systems but in a compact package that fits under 15-inch wheels. It’s perfect for enthusiasts like us who want a bit more performance while still keeping that classic vibe. Plus, everything you need is included in the box, down to the fittings, which is a nice touch. No scrambling for parts when you’re ready to install.

The rotor itself is no joke—made from 6061 T-6 billet aluminum and anodized black, it’s bolted right to the rotor for a secure fit. And the pre-assembled hubs? They come with quality bearings and races already installed. They’re packed with Redline synthetic grease, so you know they’re ready to roll right out of the box.

As for the S4 caliper, it’s designed with four 10mm cross bolts for maximum stiffness, which means better performance under pressure. You’ve got stainless steel abutments and noise suppression springs to keep things quiet, and the hard anodized aluminum pistons are built to last. The internal crossover design is a nice touch, too, ensuring everything operates smoothly.

When it comes to maintenance, you’ll love the fact that it uses a common 4-piston pad—P/N DR1—so replacements are a breeze. And if you want to customize your look, the red powder coat finish is standard, but Baer offers custom colors if you’re feeling adventurous. Everything is made right here in the USA with US-sourced materials, which is something I always look for when I’m investing in parts for my ride.

In short, if you’re after a reliable, high-performance brake system that doesn’t skimp on style, the SS4+ is definitely worth considering. It’s a smart upgrade that keeps your classic Mustang looking sharp while giving you the stopping power you need.
