The Datsun 310/311 Roadsters are timeless icons of Japanese automotive history, capturing the “giant killer” spirit long before the Z-car ever arrived. But while the styling remains classic, the steering technology is firmly rooted in the mid-1960s. If you’ve upgraded to modern radial tires, added more horsepower, or lowered your ride height, the factory steering components have officially become a major bottleneck. At Apex Engineered, we’ve reimagined the Datsun 310/311 front-end geometry to eliminate the “vintage slop” and deliver the lightning-fast, predictable response of a modern precision machine.
The factory steering ratio on the Datsun 310/311 was designed for a different era; one characterized by skinny bias-ply tires and casual Sunday cruising. In that context, a “slow” steering box was actually a safety feature, preventing twitchy movements at high speeds. However, on modern high-grip rubber, this translates to a sluggish feel that forces the driver to “row” the wheel through tight corners. Our Quick Steering Knuckles are the ultimate solution for owners looking to modernize the driving experience.
By shortening the steering arm length at the knuckle, we effectively increase the steering speed by a significant margin. This modification allows for less physical input from the driver to achieve the same degree of wheel turn at the hub. The result is an immediate, connected feel that transforms the agility of the Datsun 310/311. You’re no longer waiting for the car to catch up to your hands; the front end responds the instant you load the steering. CNC-machined for absolute precision, these knuckles provide the structural integrity required to handle the increased leverage of modern tires without the deflection found in aged factory iron.
Vague steering feedback is rarely the fault of a single part; it is usually the cumulative result of “play” across the entire multi-point linkage system. On a 60-year-old chassis, this is often caused by a flexy factory center link and worn-out pivot points. If your steering wheel has a “dead zone” in the center, where you can wiggle the wheel an inch in either direction without the tires actually moving, your components are deflecting. We’ve addressed this core structural weakness with our heavy-duty Datsun 310/311 Center Link.
Standard factory center links were made from materials that simply weren’t intended to withstand the lateral forces generated by modern suspension setups. Our upgraded center link is engineered for maximum rigidity, acting as the unyielding backbone of your steering system. It ensures that every movement of the steering box is translated directly to the tie rods without losing energy to component flex. To round out the foundation, our high-strength Front Lower Ball Joints replace dated, high-wear factory units, restoring the chassis confidence needed for high-speed maneuvers.
As soon as you lower a Datsun 310/311 to achieve that perfect stance, or move to aggressive, wide wheel fitments, the factory tie rods become a massive liability. Clearance issues can lead to binding against the frame, while the limited adjustability of the original hardware makes it nearly impossible to achieve a perfect alignment on a modern rack. Our Adjustable and Low-Profile Tie Rods were designed specifically to solve these high-performance headaches.
Our adjustable units allow for granular, on-car toe settings. This is critical for dialing in turn-in characteristics and ensuring the tires track perfectly straight on the highway. For builders pushing the limits of wheel offset, our low-profile design provides the necessary clearance to prevent interference with the chassis during full-lock turns. This isn’t just about making the car handle better; it’s about giving you the engineering freedom to build your Roadster exactly how you want. These parts provide the finishing touch to a total steering overhaul, ensuring your alignment stays true even under the harshest track conditions.
Upgrading your Datsun 310/311 with Apex Engineered parts isn’t about erasing the soul of the Fairlady; it’s about giving it the precision it has always deserved. By correcting the geometry, increasing steering speed, and reinforcing the entire linkage, you transform a nervous vintage cruiser into a sharp, responsive athlete. Stop fighting 60-year-old engineering and start enjoying the drive. It’s time to take control of the road.
