Upgrade the front braking performance of your 2015-2023 Ford Mustang with the Baer Brakes SS4+ Deep Stage Front Brake Kit, part number BAE4261428FR. Designed for lighter-weight vehicles and applications using a parachute, this system delivers the benefits of a larger brake package in a compact configuration designed to fit select 15-inch wheels. The kit is compatible with S550 Mustangs except the GT350 and is available with a distinctive Fire Red powder-coated finish. For a full-weight S550 Mustang where braking performance is relied on more heavily, Baer Brakes recommends the SS4+ Version 2.0 system instead.
The system includes a 4-piston S4 caliper paired with an 11.625-inch by 0.705-inch two-piece slotted and drilled zinc-plated rotor. The rotors are pre-assembled with NAS-grade stainless steel hardware, while mounting hardware is included for a more straightforward installation. The caliper uses the popular HB540 pad type and is manufactured in Phoenix, Arizona. Hard-anodized aluminum pistons, stainless steel abutments, and noise-suppression clips help support reliable operation and controlled pad movement.
The Baer Brakes SS4+ Deep Stage system provides a lightweight front brake solution for performance-oriented Mustang builds where wheel clearance, reduced system weight, and dependable stopping power are important considerations. Its two-piece construction, powder-coated calipers, and slotted and drilled rotors provide a purposeful combination of function and appearance.
