• Direct replacement design for factory brake systems and stock calipers
• Vented rotor construction for front brake applications
• Black e-coating helps protect exposed surfaces from corrosion
• High-carbon metallurgy in most applications supports quieter operation and improved crack resistance

Product Details

StopTech Sport Cross-Drilled & Slotted Disc Brake Rotors are part of the StopTech Sport rotor line, which focuses on replacement brake discs that retain OE-style fitment while adding performance-oriented surface machining. The slotted X-drilled design helps reduce glazing, improve initial bite, and maintain more consistent wet and dry braking behavior. With a 9.685-inch outside diameter, 0.815-inch discard thickness, 0.880-inch nominal thickness, and straight vane venting, this rotor is built around the dimensions needed for the listed front left applications. The floating disc mounting and coated finish further support durability in everyday use. Part number 127.62023L is a practical choice for drivers replacing a worn front rotor on vehicles such as the Chevrolet Cavalier, Pontiac Sunbird, and Buick Skylark.

Common Issues This Rotor Can Address

• Brake pulsation from a worn or heat-affected front rotor
• Reduced initial bite from glazed pad contact surfaces
• Excess brake dust buildup on the rotor face
• Corrosion on exposed rotor surfaces
• Inconsistent braking feel in wet or dry conditions

Installation Notes and Tips

Verify rotor dimensions, bolt pattern, and front left position before installation. This rotor uses a 5-lug, 100 mm bolt circle and a 58.4 mm center hole diameter. Inspect pads, caliper condition, and hub surfaces during replacement to help ensure even contact and proper rotor seating. Confirm vehicle-specific fitment for the exact model year and trim, especially where notes exclude performance packages. Part number 127.62023L should be matched to the application listed in the fitment table.

Quality Assurance

StopTech builds this rotor with corrosion-resistant black e-coating and high-carbon metallurgy in most applications to support durability, quieter operation, and improved crack resistance. The design is intended as a direct replacement for factory brake systems using stock calipers.
