The drilled and slotted braking surface helps maintain consistent pad contact, while the zinc silver hat finish and rust resistant coating support long-term appearance and corrosion control.

Detailed Description

Part number 631-67017L is built for Nissan front brake applications that require a directional, vented rotor on the left side. It is a direct fit for 1984-1988 Nissan 300ZX front left, 1987-1988 Nissan 200SX front left, and 1989 Nissan 300ZX front left with vehicle production to 1/89. The drilled and slotted face is paired with a plain disc finish and a zinc silver hat finish for a clean, service-ready look.

This rotor is sized with a 274 mm outside diameter, 35.6 mm overall height, 81 mm center hole diameter, and 10.5 mm stud/lug hole diameter. The 5-bolt, 5-lug layout and 103 mm bolt circle diameter match the listed Nissan fitments. If you are replacing a worn front left rotor on a Nissan 300ZX or Nissan 200SX, 631-67017L provides the specified dimensions and surface type for the application.

Common Problems This Rotor Addresses

• Brake pulsation from a worn or uneven front rotor
• Reduced braking consistency from heat-affected rotor surfaces
• Corrosion on the rotor hat or exposed metal surfaces
• Rotor replacement needs on Nissan 300ZX and Nissan 200SX front left applications
• Fitment issues caused by incorrect diameter, thickness, or bolt pattern

Installation Notes and Tips

Confirm the vehicle is a front left application before ordering. Verify rotor diameter, center hole diameter, bolt circle diameter, and thickness against the removed part, especially on the 1989 Nissan 300ZX with production to 1/89. Clean the hub mounting surface before installation and inspect pads, caliper condition, and wheel hardware for wear that could affect rotor performance.

Quality Assurance

Dynamic Friction supplies this rotor with a rust resistant coating and zinc silver hat finish to support corrosion resistance in normal brake service. Part number 631-67017L is built to the listed dimensional and fitment specifications for the confirmed Nissan applications.
