Quick reference
Verify wheel diameter meticulously: 1991 was the final year for 16-inch wheels on Turbo models; 1992-1996 used 17x9 rears (40300-5Pxxx series) with incompatible tire sizes and brake caliper clearance
JDM market Z32s may have earlier adoption of 17-inch wheels or different OEM suppliers; verify casting marks match 40P01 pattern
Right and rear wheels are not side-specific on Z32 (symmetrical design), but verify directional tire mounting if present
Context
When sourcing a replacement rear rim for your 1991 Nissan 300ZX Twin Turbo, verify you're acquiring the correct 16x9 specification rather than the narrower 16x8 used on naturally aspirated models or the 17-inch wheels introduced in 1992. The OEM Nissan part number 40300-40P01 designates the 16x9 rear 'turbine' wheel specific to 1990-1991 TT production, featuring a +45mm offset, 5x114.3mm bolt pattern, and 66.1mm center bore. These cast aluminum wheels interchange freely within 1990-1991 Turbo chassis (Z32) but require verification of the casting mark 40P01 to avoid accidentally purchasing the 17-inch 1992+ variant. Inspection priorities include checking for hairline cracks between the turbine spokes—a common fatigue point on 30-year-old castings—along with bent outer lips and air leaks around the welded seam. Installation requires 72-87 ft-lb torque in a star pattern using the factory acorn lugs; remember this is a staggered width setup (8.5-inch front, 9-inch rear), limiting tire rotation to side-to-side only.
