The Datsun S30 chassis is a masterpiece of automotive design, but its 1970s suspension technology often struggles to keep up with modern horsepower and high-grip tire compounds. While our Pro Touring kits offer a massive leap over factory equipment, we knew there was a segment of the Z community that wanted something more aggressive. They wanted a setup designed for the track that could go head to head with modern sports cars.
That ambition led to the creation of the Track Attack Complete Front and Rear Kit. By fundamentally reimagining the geometry of the 240Z, 260Z, and 280Z, we have created a bolt on system that moves the S30 into the territory of purpose built race cars. Here is the technical breakdown of how this kit redefines the driving experience.
The most striking feature of the Track Attack Complete Front and Rear Kit is the move to an inboard rear suspension. In a standard layout, the coilover is attached directly to the hub or control arm. In our pushrod style system, the movement of the wheel is transmitted through a linkage to coilovers mounted horizontally inside the chassis.
One of the primary enemies of handling is unsprung weight. This is the mass of the components not supported by the suspension, such as wheels, tires, and portions of the suspension arms. By moving the heavy coilovers inboard, we significantly reduce the weight that the suspension has to manage as it reacts to the road. This allows the tires to stay in more consistent contact with the pavement, especially through high speed undulations on a race track.
The cantilever design of the inboard setup allows for a more progressive suspension rate. As the suspension compresses, the leverage on the shock changes, allowing for a ride that can be compliant over minor bumps but incredibly firm and supportive under heavy cornering loads. This provides a level of mechanical grip that a traditional vertical coilover simply cannot match.
The factory S30 spindles are a major bottleneck for anyone looking to run modern brakes or achieve a wider track width. Our Track Attack Complete Front and Rear Kit solves this by utilizing 370Z spindles to revolutionize your front end capabilities.
By switching to the 370Z spindle, you gain access to a massive aftermarket of performance brake kits and wheel configurations that were previously impossible to fit on a vintage Z. This ensures that your stopping power is just as modern as your suspension geometry.
Precision is everything on the track. This kit includes caster adjustable control arms and toe adjustable tie rods. This allows you to dial in an aggressive front end alignment that maximizes the tire contact patch during hard turn in. By eliminating the factory steering vagueness, the car goes exactly where you point it, providing the driver with the confidence to push deeper into every braking zone.
When you increase the grip levels of a 50 year old car, you also increase the stress on the drivetrain. The Track Attack Complete Front and Rear Kit includes a rigid rear subframe that is engineered to handle the loads of high horsepower engines.
The subframe is designed to be compatible with Nissan 370Z differentials. These units are significantly stronger than the original R180 or R200 diffs and offer a wide range of gear ratios and limited slip options. This ensures that whether you are running a high revving L-series or a modern turbo swap, your rear end can put that power to the ground reliably.
A suspension kit is only as good as the chassis it is attached to. The Track Attack Complete Front and Rear Kit functions as a comprehensive bracing solution for the S30. The rear subframe and inboard shock mounting structure tie the rear of the car together, virtually eliminating the chassis flex that often plagues these older unibody cars.
By replacing the stamped steel factory arms with our rear lower control arms and tubular subframe components, you create a rigid foundation. This rigidity ensures that the suspension geometry stays true even under the most extreme cornering forces, providing a predictable and repeatable driving experience lap after lap.
While this kit is optimized for racing, it is designed with the same attention to detail and build quality as all Apex Engineered products.
The Track Attack series is not just an upgrade; it is a total transformation. It is the definitive choice for the S30 owner who wants to see exactly what this legendary chassis is capable of when paired with 21st century engineering. If you are ready to stop making compromises, the Track Attack Complete Front and Rear Kit is the final word in S30 performance.
