Product Line Details: StopTech Sport Cross-Drilled Disc Brake Rotors

The StopTech Sport Cross-Drilled Disc Brake Rotors line focuses on performance-oriented rotors that feature cross-drilled surfaces to improve cooling and reduce brake fade during aggressive driving. This product line uses vented rotor construction and a coated hat finish to enhance durability and maintain consistent braking performance under demanding conditions. The 128.42080L rotor is part of this line, offering a balance of performance and longevity for sport and daily driving applications.

Technical Specifications and Features

This disc brake rotor has a nominal thickness of 1.106 inches (28.1 mm) and a discard thickness of 1.024 inches (26.0 mm), ensuring a long service life before replacement is necessary. The rotor’s outside diameter measures 12.583 inches (319.6 mm), with an overall height of 1.937 inches (49.2 mm). It features a vented design with straight vanes to optimize airflow and heat dissipation. The rotor is cross-drilled (X drilled) to further improve cooling and reduce brake fade. The hat section is coated to resist corrosion, and the rotor mounts using a floating disc system to accommodate thermal expansion. It includes five stud/lug holes with a 4.5-inch (114.3 mm) bolt circle diameter and a center hole diameter of 2.677 inches (68.0 mm).

Compatible Vehicles and Applications

This StopTech rotor is compatible with a range of INFINITI and Nissan models, including but not limited to:

• INFINITI 350Z, 370Z, EX35, EX37, FX35, FX45, G25, G35, G37, M35, M35h, M37, M45, M56, Q40, Q70, Q70L, QX50, QX70
• Nissan Altima, Maxima, Murano

Common Issues Addressed by This Rotor

• Brake fade caused by excessive heat buildup during spirited driving
• Uneven rotor wear and reduced braking efficiency
• Corrosion and rust on rotor hats affecting longevity
• Vibration or noise due to rotor warping or poor heat dissipation
• Insufficient cooling leading to premature brake component wear

Installation Notes and Tips

• Ensure rotor discard thickness is checked before installation to confirm suitability
• Use proper torque specifications for lug nuts to avoid rotor warping
• Inspect brake pads and replace if worn to maintain optimal braking performance
• Clean rotor surface with brake cleaner before installation to remove any contaminants
• Verify compatibility with ABS systems as this rotor does not include an ABS tone ring
