Detailed Product Description

This StopTech Sport Cross-Drilled Disc Brake Rotor (part number 128.61087L) is specifically designed for Ford Mustang models requiring a 5-lug rotor with a 114.3 mm (4.5 inch) bolt circle diameter. The rotor features a vented design with straight vanes that promote airflow to reduce heat buildup during braking. The cross-drilled surface pattern helps to evacuate gases and debris, improving pad bite and overall braking response. The coated hat finish provides corrosion resistance, helping maintain rotor integrity over time. With a floating disc mounting system, this rotor allows for slight movement to reduce stress and improve braking smoothness.
