Deep Stage SS4+ Rear Bra ke System 15- Mustang

The Deep Stage SS4+ Rear Brake System 15-Mustang by BAER BRAKES is engineered for drivers demanding premium stopping power and fade resistance in high-performance applications. Built for 2015–2018 Ford Mustang models, this rear brake kit transforms factory stopping capability into competition-grade confidence, whether you're tracking your vehicle, towing heavy loads, or simply refusing to compromise on safety. The SS4+ designation signals BAER's advanced thermal management and pad durability—specifications that matter when brakes are pushed to their limits.

This rear brake assembly features a 4-piston caliper architecture that distributes braking force evenly across a 11.62-inch drilled and slotted 2-piece iron rotor, maximizing heat dissipation and reducing pad fade during sustained deceleration. The drilled design vents hot gases; the slotted geometry scrubs glazed material from brake surfaces, restoring consistent friction. Cast iron rotors deliver superior thermal capacity compared to composite alternatives, while the aluminum caliper body keeps unsprung weight reasonable. Red powder coat finish provides corrosion resistance and matches modern Mustang aesthetics without sacrificing functional design—a detail that distinguishes quality brakes from budget alternatives.

Vehicle enthusiasts, track day drivers, and owners of modified Mustangs benefit most from rear brake upgrades; factory rear systems often lag when front brakes receive attention, creating imbalanced stopping geometry. The Deep Stage SS4+ Rear Brake System 15-Mustang restores proportional braking bias, reduces stopping distance, and prevents rear lockup under hard cornering—critical for driver safety and vehicle control. Installation requires mechanical competency or professional service; confirm fitment with your specific 2015–2018 Mustang generation and existing brake component compatibility before ordering. Weight at 80 lbs reflects the substantial iron and aluminum construction that ensures durability across countless heat cycles.
