The Nissan Z31 300ZX is a legend in its own right. With its sharp ’80s lines and unmistakable profile, it’s a car that stands out in any crowd. But as much as the styling has aged gracefully, the steering and suspension have not. The factory geometry was designed for the roads of the mid-1980s — and after decades of wear, even the best-maintained Z31s can feel loose, vague, and disconnected.
If you’ve ever taken a corner and felt more body roll than confidence, you already know the Z31 can be better. The good news? Modern upgrades from Apex Engineered can bring precision back to your driving experience without stripping away the character that makes this car special.
Think of suspension geometry as the invisible blueprint that controls how your tires interact with the road. Every degree of camber, caster, and toe impacts how the car turns in, holds a line, and responds to your inputs. Over time, rubber bushings wear, factory tolerances drift, and components flex in ways that blunt your control.
Correcting geometry doesn’t just improve handling — it restores the connection between you and the car. And for a driver’s car like the Z31, that connection is everything.
1. Adjustable Front Control Arms
Factory arms lock you into fixed geometry, limiting your ability to fine-tune alignment. Apex’s adjustable design lets you dial in camber and caster to match your setup — whether you’ve kept the stock ride height or gone lower for a more aggressive stance.
2. Quick Steering Knuckles
By reducing the steering ratio, these knuckles deliver a sharper, more immediate response to every input. They also help correct geometry changes on lowered cars, reducing bump steer and improving tire contact through corners.
3. Adjustable Front Tie Rods
Alignment isn’t complete without precise toe control. These tie rods give you the range needed to fine-tune steering feel, eliminate wandering, and maintain stability at all speeds.
With these upgrades working together, your Z31 transforms from “good for its age” to genuinely confidence-inspiring. The steering wheel feels more connected to the front tires. The car tracks true on the highway. In corners, body roll is reduced, and the front end feels planted instead of floating.
It’s not about making the Z31 something it’s not — it’s about revealing the capability that’s been hiding there all along.
Apex Engineered designs every Z31 component with precision tolerances and a true bolt-on fit. No compromises. No modifications. Just purpose-built parts that work together to create the kind of handling balance you can feel in every mile.
