Description
For racers who demand uncompromised stopping power in a lightweight, beadlock-wheel-compatible package, Baer offers the SS4+ Deep Stage 2.0 Rear Brake Kit for the 2015–2023 Ford Mustang S550 (excluding GT350).
This system features Fire Red S4 4-piston calipers paired with 12” slotted-only 2-piece rotors that are pre-mounted to black anodized 6061-T6 billet aluminum hats using high-grade NAS stainless hardware. It’s engineered for drag racing at full vehicle weight, and still performs reliably on the street.
Baer optimized this setup for maximum performance in a compact form — allowing clearance for most 15” drag and beadlock wheels, without sacrificing rotor mass or braking efficiency.
Note: Comes standard with high-friction drag pads for peak performance at the strip. Expect increased dust and noise as part of this performance-tuned design.
