The front control arm is the most critical link between your chassis and the pavement. It dictates how your tires interact with the road, how your steering feels in your hands, and how your vehicle maintains its geometry under extreme lateral loads. For owners of classic Japanese icons like the S30, S130, Z31, and the Datsun 510, the factory front control arms are often the primary bottleneck preventing a truly modern driving experience.
At Apex Engineered, we designed our front control arms to bridge the gap between vintage soul and modern performance. By replacing aging stamped steel with high-strength chromoly tubing and precision rod ends, we provide a foundation that can handle the stresses of modern tires, increased horsepower, and aggressive track use.
To understand why an upgrade is necessary, you must first understand what the front control arms do. These components are responsible for locating the bottom of the spindle and allowing the suspension to travel vertically while resisting horizontal forces.
On a factory S30 or 510, these arms were engineered with rubber bushings and thin steel. Over decades, the rubber degrades and the steel can fatigue. More importantly, those rubber bushings are designed to deflect. While this deflection might offer a slightly softer ride on the highway, it is disastrous for performance. When you dive into a corner, the rubber compresses, causing your alignment to shift mid-turn. This results in vague steering and unpredictable handling. Upgrading to Apex Engineered front control arms replaces that uncertainty with surgical precision.
Every set of Apex Engineered front control arms is constructed using high-quality materials that far exceed factory specifications. We utilize tubular chromoly steel, which offers a superior strength-to-weight ratio compared to original cast or stamped parts.
Weight savings in this area are particularly valuable because it is unsprung weight. Reducing the mass of components that move with the wheel allows your dampers to work more effectively. Your suspension can react faster to bumps and undulations in the road, keeping the tire contact patch consistent and improving overall grip. When you install our front control arms, you aren’t just adding strength; you are making the entire suspension system more efficient.
One of the greatest challenges when lowering a classic Datsun or Nissan is maintaining proper suspension geometry. Factory front control arms offer almost zero adjustability. Once you change the ride height, you are often stuck with “hand-me-down” camber and caster settings that can lead to poor handling and premature tire wear.
Our front control arms feature high-quality rod ends that allow for precise, on-car adjustments. This means you can dial in the exact camber and caster settings required for your specific driving style. Whether you need an aggressive setup for the local autocross or a balanced alignment for a long-distance canyon run, our arms provide the flexibility to get it right.
The S30 (240Z, 260Z, 280Z) is the bedrock of the vintage Z community. However, the original front end is known for feeling “light” or “floaty” at high speeds. This is often due to the deflection in the factory arms. Our S30 front control arms eliminate this movement. By pairing these with a modern steering rack and high-quality coilovers, you can finally experience the S30 chassis as it was meant to be: responsive, communicative, and incredibly fast through the corners.
The S130 (280ZX) and Z31 (300ZX) are often seen as grand tourers rather than raw sports cars. A large part of that perception comes from their softer factory suspension tuning. Upgrading to Apex Engineered front control arms for these models completely changes the personality of the car. It sharpens the turn-in and provides a level of feedback through the steering wheel that the factory never intended. These arms allow Z31 and S130 owners to keep up with much newer performance cars on the track.
The Datsun 510 is a giant killer, but it requires a rock-solid foundation to live up to its reputation. Because the 510 is a lightweight chassis, it is extremely sensitive to suspension changes. Our 510 front control arms are built to provide maximum rigidity for the 1600 and 510 platforms. They ensure that even under the most demanding racing conditions, your suspension geometry remains static, allowing you to push the car to its absolute limit with confidence.
We don’t just manufacture parts; we engineer solutions for enthusiasts. Every set of front control arms we produce is the result of rigorous testing and a deep understanding of these specific platforms. We know the weak points of the factory Z and 510 suspension because we drive these cars ourselves.
When you invest in our front control arms, you are getting:
If you are serious about the handling of your vintage Nissan or Datsun, you cannot overlook the front control arms. They are the link between your steering inputs and the road. By upgrading to a rigid, adjustable, and lightweight solution from Apex Engineered, you are transforming the driving dynamics of your car.
Stop settling for 50-year-old technology and vague steering feel. Give your S30, S130, Z31, or 510 the precision it deserves. Experience the difference that high-quality front control arms can make on your next drive.
