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.\u003c\/p\u003e\u003cp\u003eThis 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.\u003c\/p\u003e\u003ch2\u003eCommon Problems This Rotor Addresses\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eBrake pulsation from a worn or uneven front rotor\u003c\/li\u003e\n\u003cli\u003eReduced braking consistency from heat-affected rotor surfaces\u003c\/li\u003e\n\u003cli\u003eCorrosion on the rotor hat or exposed metal surfaces\u003c\/li\u003e\n\u003cli\u003eRotor replacement needs on Nissan 300ZX and Nissan 200SX front left applications\u003c\/li\u003e\n\u003cli\u003eFitment issues caused by incorrect diameter, thickness, or bolt pattern\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eConfirm 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.\u003c\/p\u003e\u003ch2\u003eQuality Assurance\u003c\/h2\u003e\u003cp\u003eDynamic Friction supplies this rotor with a rust resistant coating and zinc silver hat finish to support corrosion resistance in normal brake service.
