This system boasts a robust 4-piston S4 caliper paired with a 12-inch by 1.100-inch two-piece slotted rotor, utilizing the popular DR1/HB100 pad type. The slotted rotors are securely mounted to 6061 billet aluminum hats with high-grade NAS stainless hardware, and they come pre-assembled for your convenience. Rest assured, all additional mounting hardware is included as well.

The SS4+ 2.0 Deep Stage system is crafted for those who want to push their limits at the strip while still enjoying a reliable setup for street driving. It’s designed to fit many 15-inch wheels and larger, making it a versatile choice for your vehicle.

Note: This system features high-friction pads optimized for drag racing, which can produce a bit more dust and noise than standard pads. You can choose from eye-catching caliper colors like Clear and Fire Red to match your style.

Compatible with 2015-2023 Mustang (S550) models, excluding the GT350.
