If you're looking to upgrade your braking system without sacrificing your 17-inch wheels, the Baer SS4+ is a solid choice. This rear system features a robust S4 4-piston caliper paired with a 13-inch, two-piece slotted and drilled rotor that’s zinc plated for durability. You get stainless steel brake hoses included, and the calipers come with D.O.T. compliant dust and weather seals, so you know they’re built to last. Plus, we use quality bearings and high-grade NAS stainless hardware for the pre-assembled rotor, ensuring everything fits together nicely.

The SS4+ is like a mini version of Baer’s larger brake systems, designed specifically for those of us who want to stick with 17-inch wheels. It’s a great option if you want to keep that classic look but also enjoy the performance benefits of a more advanced braking setup. Just a heads-up: park brake cables aren’t included with this kit.

Fitment:

• Compatible with stock Ford 9-inch big bearing housing.
• Offers both 5 x 4.500 inch and 5 x 4.750 inch wheel bolt patterns.
