Stoptech 128.42076L Disc Brake Rotor - Front Left

StopTech Sport Rotor for Nissan 350Z and INFINITI G35

The StopTech Sport Cross-Drilled Disc Brake Rotor is a direct replacement front left rotor for factory brake systems and stock calipers. Built for the 2003-2008 Nissan 350Z and select 2003-2004 INFINITI G35 applications, part number 128.42076L combines OE-style fitment with a drilled surface for improved heat management and braking response.

The StopTech Sport Cross-Drilled Disc Brake Rotors line focuses on replacement rotors that retain factory compatibility while adding performance-oriented surface treatment and corrosion protection. For drivers searching for a front left brake rotor for Nissan 350Z or INFINITI G35 Brembo brake applications, this rotor is built to match the original mounting dimensions and hub interface.

• Direct replacement disc brake rotor for factory brake systems and stock calipers
• X-drilled surface helps disperse heat and brake dust
• Drilled design helps reduce pad glazing and improve initial bite
• Black e-coating helps protect against corrosion
• High-carbon metallurgy in most applications for quieter operation and improved crack resistance
• Vented rotor construction with pillar vane style
• Coated hat finish for added durability
• Part number 128.42076L

Detailed Fitment and Construction

This vented front left rotor measures 12.756 inches in outside diameter, 1.181 inches nominal thickness, and 1.118 inches discard thickness. It uses a 5-lug pattern with a 4.500-inch bolt circle, a 2.677-inch center hole diameter, floating disc mounting, and one miscellaneous hole. The rotor is engineered for the front left position on 2003-2008 Nissan 350Z and 2004 INFINITI G35, plus 2003 INFINITI G35 Brembo brake applications noted for the front left side. Part number 128.42076L is a practical choice when replacing a worn or heat-affected rotor on these platforms.

• Fits 2003-2008 Nissan 350Z, front left
• Fits 2004 INFINITI G35, front left
• Fits 2003 INFINITI G35, front left, Brembo brakes; Fr 8/02 - To 2003

Common Issues This Rotor Can Address

• Brake pulsation caused by rotor wear or uneven surface condition
• Reduced braking response from heat buildup during repeated stops
• Pad glazing from elevated rotor temperatures
• Corrosion on exposed rotor surfaces
• Noise associated with worn or heat-stressed brake discs

Installation Notes and Tips

Verify rotor diameter, thickness, and front left position before installation. Clean the hub face thoroughly to help prevent runout-related brake pulsation, and inspect pads and caliper hardware for wear before reassembly. Because this rotor is drilled and vented, proper bedding-in of the brake pads is important for stable performance and even transfer layer formation.

Quality Assurance

StopTech designs this rotor as a direct replacement for factory brake systems, with black e-coating for corrosion resistance and high-carbon metallurgy used in most applications for quieter operation and improved crack resistance. The drilled sport rotor construction is intended to maintain OE-style fitment while improving heat and dust dispersal.
