Front Right Brake Rotor - 1991 300ZX Z32

For the 1991 Nissan 300ZX Twin Turbo (Z32), the front right brake rotor is a critical 280mm ventilated disc distinct from the smaller NA variant. Genuine Nissan units carry OEM number 40206-30P01 (right hand) or the interchangeable 40206-30P00, with casting mark '30P00' stamped on the hat. When junkyard hunting, restrict searches to 1990-1996 VG30DETT models exclusively; the naturally aspirated VG30DE employs smaller 260mm rotors with iron 2-piston calipers that will not mount. Inspect carefully for radial heat cracks, measure remaining thickness against the 28.0mm minimum specification, and verify the cooling vanes are not clogged. During installation, torque wheel lugs to 87-116 ft-lbs in a star pattern to prevent warping these 30mm thick castings, and always resurface or replace pads simultaneously. Common failures include pad imprinting from aggressive parking brake use, hub surface corrosion causing runout pulsation, and premature wear from seized guide pins—always clean the hub mounting face thoroughly before fitting replacement 40206-30P00 series rotors.
