Rear Stabilizer/Sway Bar - 1991 300ZX Z32

The rear stabilizer bar on the Z32 Nissan 300ZX Twin Turbo (VG30DETT) is a critical chassis component that reduces body roll during aggressive cornering. OEM Nissan part numbers include 56211-30P00 for early production and the superseded 56211-40P00 for later models, with both measuring approximately 19mm in diameter—significantly thicker than the NA counterpart. When sourcing from junkyards, target 1990-1996 USDM 300ZX TT or 1989-2000 JDM Fairlady Z Z32 variants; verify the "30P" casting mark on the bar's center section to confirm turbo specification. Inspection should focus on bushing deterioration at the 54613-30P00 bracket locations and end-link ball joint wear, as the torsional steel rarely fails unless corroded by road salt. Installation requires dropping the rear exhaust heat shield on twin-turbo models for clearance, and torque the 14mm chassis bolts to 35-40 Nm. Always replace rubber bushings with polyurethane upgrades or fresh OEM units to prevent squeaking, and never interchange with VG30DE naturally aspirated bars which are visibly thinner.
