1984 Nissan 300 ZX (Z31) Dimensions, Size & Specs

The curb weight of the 1984 Nissan 300 ZX (Z31) ranges between approximately 1390 kg to 1430 kg (3062 to 3151 pounds). Its maximum weight, which includes passengers and cargo, ranges between 1760 kg to 1810 kg (3881 to 3990 pounds). This weight range reflects a solid sports coupe build balancing performance and structural integrity.

The 300 ZX (Z31) comes with rim sizes ranging from 6.5J x 15 up to 7J x 16. Tire sizes compatible with this vehicle include 215/60 R15, 225/50 R16, and 205/55 R16. These tire and rim options provide flexibility for drivers seeking either comfort or sportier handling characteristics.

Yes, the Nissan 300 ZX (Z31) will fit comfortably into a standard garage. Given its height of 1310 mm (51.6 inches) and width of 1725 mm (67.9 inches), it is compact enough to fit within typical garage door widths and heights, which often exceed 2100 mm (82.7 inches) in height and 2400 mm (94.5 inches) in width. This makes parking and storage convenient for most residential garages.

Compared to the Nissan 280 ZX (S130), the 300 ZX (Z31) is slightly larger in most dimensions, which contributed to a more modern and aerodynamic profile. The Z31's length of 4540 mm (178.7 inches) and width of 1725 mm (67.9 inches) represent an increase from the S130, improving interior space and road presence. This size evolution reflected Nissan’s move toward a more advanced and performance-oriented sports coupe.

In comparison to similar sports coupes of the mid-1980s, the Nissan 300 ZX (Z31) was relatively compact but well-proportioned. For example, it is slightly larger than the Mazda RX-7 (FB) but smaller than the Chevrolet Corvette C4. Its length of 4540 mm (178.7 inches) and height of 1310 mm (51.6 inches) made it agile yet comfortable, designed to balance sporty handling with everyday usability.

The Nissan 300 ZX (Z31) has a roof load capacity of 100 kg (220 pounds). This means that if equipped with proper roof racks, the vehicle can safely carry additional cargo such as luggage or sports equipment on the roof, provided the load does not exceed this weight limit. It extends the car’s practicality for trips requiring extra storage outside of the cabin and trunk.

The moderate dimensions of the Nissan 300 ZX (Z31) provide several driving and parking advantages. Its length and width allow for nimble cornering and ease of maneuvering in urban environments, while the relatively low height gives a sporty, aerodynamic profile. These size traits make parking in tighter spaces easier than larger sports coupes, and the vehicle is compatible with typical parking structures and residential garages, enhancing its usability.

While the Nissan 300 ZX (Z31) is primarily designed as a two-seater sports coupe, its exterior dimensions allow for a reasonably spacious cockpit for driver and passenger. The width of 1725 mm (67.9 inches) provides adequate shoulder room, and the length and height contribute to sufficient legroom and headroom, especially given its low-slung sports car design. However, rear passenger or cargo space is limited, emphasizing its focus on sporty performance rather than utility.

The curb weight of 1390 to 1430 kg (3062 to 3151 lbs) coupled with the car's dimensions (length 4540 mm, width 1725 mm, height 1310 mm) directly impacts the 300 ZX’s performance positively by providing a stable and balanced platform. This weight is moderate for a sports coupe, allowing for responsive acceleration and nimble handling while maintaining enough solidity to handle well at high speeds. The dimensions contribute to a low center of gravity and aerodynamic efficiency, further enhancing its sporty driving characteristics.
