1997+ (Japan)

In 1997, all Z32 models adopted the twin-turbo front fascia, presumably to lower production costs.
In 1998, for 1999, the Z32 received a cosmetic update. To name some, the differences included:

• New front fascia
• New side-skirts
• New taillights (featuring clear turn signal lenses, chrome housings, and black pinstriping)
• New center panel ("300ZX" became red instead of silver)
• New rear spoiler
• Light gold gauges (similar to the Maxima from the same era)
• A slew of new interior options (including carbon fiber accents, "lift-style" window switches, and optional Recaro SR seats).

The 1998 Z32 also received a revised Manual Transmission, which used stronger synchronizers to combat a common "soft-synchro" problem that had become apparent on earlier Z32s.
