If you're looking to upgrade your braking game without sacrificing that classic look, the Baer SS4+ rear brake system is a solid choice. This setup features a robust S4 4-piston caliper, paired with an 11-inch 2-piece rotor that’s been thoughtfully designed with slots and drilled holes for better heat dissipation. Trust me, when you're pushing your ride to the limit, you want brakes that can handle the heat. The zinc plating on the rotor adds an extra layer of protection against rust, which is always a plus in my book.

One of the standout features of this system is the stainless steel brake hoses that come with it. They’re durable and built to last, plus the calipers are equipped with D.O.T. compliant dust and weather seals. That means you can take your ride out in various conditions without worrying about dirt and grime messing up your braking performance. And let’s not forget about the NAS high-grade stainless hardware that comes pre-assembled with the rotor—no need to hunt down extra parts.

The SS4+ is engineered to fit snugly under 15-inch wheels, making it perfect for those of us who want to keep that classic look while still enjoying the benefits of modern braking technology. Just to note, this kit doesn’t come with a park brake assembly or cables, so keep that in mind when you’re planning your install.

Fitment:

• Designed for use with stock Ford 9-inch small bearing housings featuring the SHELBY logo.
• This kit accommodates both 5 x 4.500 inch and 5 x 4.750 inch wheel bolt patterns.
