The Nissan 300ZX suspension upgrades (Z31) often fly under the radar, but it’s a capable platform with serious potential. With the right suspension upgrades, your Z31 can rival modern sports cars in handling and response. This guide covers the most effective upgrades to improve the performance and confidence of your Nissan 300ZX, whether you’re daily driving or hitting the track.

Coilovers for the Z31

One of the most transformative changes you can make is swapping out the stock suspension for modern coilovers. Apex Engineered offers a full coilover kit that’s specifically designed for the Z31 platform.

Why coilovers matter:

  • Custom ride height settings
  • Tunable damping for street or track
  • Lower center of gravity for flatter cornering

Reinforce the Suspension Foundation

To make the most of new suspension components, start by reinforcing the base of the car.

  • Front Crossmember: A rigid base for front suspension geometry.
  • Differential Mount (Solid or Bushing): Prevents unwanted flex and improves power delivery.

These upgrades eliminate slop and help every other suspension part work more effectively.

Upgrade Control and Steering Components

A major handling upgrade for the Z31 comes from replacing tired stock arms and tie rods. Apex Engineered has you covered:

  • Adjustable Front Tie Rods
  • Front Control Arms
  • Quick Steering Knuckles

These parts dramatically improve steering precision, feedback, and adjustability.

Optimize Rear-End Stability

Don’t neglect the rear suspension if you’re chasing high-speed stability and confidence.

  • Rear Suspension Kit
  • Rear Strut Brace

These upgrades improve rear grip and chassis rigidity under load.

Additional Upgrades Worth Considering

  • Transmission Mount: Keeps drivetrain tight under hard acceleration
  • Power Braces: Add structural support between key suspension points

Tuning Tips for Z31 Owners

  • Don’t overlook alignment: proper toe and camber are just as important as the parts you bolt on
  • Upgrade bushings to polyurethane for better response without harshness
  • Keep ride height functional: too low can cause bump steer and poor geometry

A well-built Z31 suspension setup makes this 80s icon drive like something decades newer. With the right parts and some smart tuning, the Nissan 300ZX becomes a serious contender on the street or circuit.
