If you're looking to upgrade your braking system, the SS4+ Deep Stage Drag Race System is worth considering. This front brake setup features a robust S4 4-piston caliper paired with an 11-inch, two-piece rotor that’s both slotted and drilled, all while being zinc plated for extra durability. What I really appreciate is that Baer has designed these calipers with D.O.T. compliant dust and weather seals, which means you can hit the streets without worrying about debris messing things up. Plus, the quality bearings and NAS high-grade stainless hardware used in the pre-assembled rotor really stand out—this is a solid piece of engineering. Now, the SS4+ isn't just any brake system; it's specifically crafted for heavy, fast cars that might also see some street action. It’s a smaller package made to fit 15-inch wheels, but don’t let that fool you. It packs a punch just like Baer’s larger systems. The rotors are vented for better heat dissipation, and those dust seals on the calipers? They’re a game-changer for longevity. When it comes to fitment, this system is designed to work seamlessly with 1974-1978 Ford Mustang II spindles, so if you've got one of those, you’re in luck.

Why Go for the SS4+?

• You get all the benefits of Baer’s larger brake systems, but in a compact design that fits snugly under 15-inch wheels.
• It’s engineered for heavy, fast cars, yet it’s versatile enough for street use.
• The 6061 T-6 billet aluminum hat is anodized black and securely bolted to the rotor, ensuring a solid connection.
• High-grade U281 fine thread stainless hardware with captured nuts means you won’t be fumbling around during installation; the rotor comes pre-assembled, too.
• You’ll also get 6061-T6 billet machined hubs, complete with Timken or SKF quality bearings and races already installed.
• These hubs come pre-assembled with everything you need—bearings, races, studs, and even billet dust caps, all packed with Redline synthetic grease for smooth operation.
• And yes, it includes ARP 1/2 inch x 20 race studs, so you know it’s built to last.

What Makes the S4 Caliper Stand Out?

• It features four 10mm cross bolts for maximum stiffness, which is crucial when you’re pushing hard on the track.
• Stainless steel abutments and noise suppression springs are included to keep things quiet and smooth.
• The pistons are hard anodized aluminum, which adds to the durability and performance.
• With an internal crossover design and dual seals that meet D.O.T. specifications, you can count on this caliper to perform under pressure.
• Each caliper has a machined logo that’s hand-painted, giving it a unique touch.
• And when it’s time for replacements, you’ll appreciate that it uses a common 4-piston pad (P/N DR1), making life a bit easier.
• It’s available in standard colors like Clear and Fire Red, with custom colors also an option if you want to match your ride.
• For that cohesive look, you can get these calipers for both front and rear setups.
• Baer uses the correct banjo style fittings, steering clear of any pipe thread nonsense.
• And let’s not forget, this system is 100 percent MADE IN USA with US-sourced materials!

In short, if you’re serious about your performance and want a brake system that can keep up with your heavy, fast car, the SS4+ is a solid choice.
