Centric 128.66057R SportStop Cross-Drilled Vented Front Brake Rotor

The Centric SportStop 128.66057R is a cross-drilled, vented disc brake rotor designed for the front passenger side of 1/2 ton (1500 HD) applications. Part of Centric's SportStop performance rotor line, it delivers enhanced stopping power for both street driving and autocross use through application-specific CNC-machined drilling patterns engineered to reduce gas, dust, and heat buildup at the rotor surface.

Built on a high-quality Centric Parts blank casting, this rotor features Power Alloy metallurgy — a material technology that is a direct descendant of the patented StopTech AeroRotor. Increased molybdenum content in the casting improves hardness and tensile strength, extends service life, and helps reduce noise, vibration, and harshness (NVH). The rotor also delivers superior resistance to cracking caused by thermal stress.

Key Features:

• Cross-drilled design with application-specific CNC-machined hole pattern
• Vented disc construction for improved heat dissipation
• Prevents brake pad glazing and increases pad bite
• Improves wet and dry braking performance by channeling water away from the rotor surface
• Power Alloy metallurgy descended from the patented StopTech AeroRotor
• Elevated molybdenum content for extended durability and reduced NVH
• Superior resistance to thermal stress cracking
• Direct-fit, no modification required
• 6-lug hub pattern
• Sold individually
