S30 Track Attack makes the most sense when your 240Z, 260Z, or 280Z is finally fast enough to show you exactly where the stock suspension is holding the car back. If you’ve noticed lazy turn-in, a rear end that gets too busy when power comes in, or a chassis that still feels unsettled even after springs, dampers, and alignment work, these kits were created to solve those issues with a more serious foundation.
That’s why Apex Engineered built their S30 Track Attack kits as three distinct upgrade paths instead of one generic answer. Some cars need front-end authority first. Some need the rear structure and driveline brought up to the level of the rest of the build. Some are already at the point where doing one end at a time just delays the real solution. The right kit depends on what the car is doing wrong once you actually lean on it.
The S30 TRACK ATTACK Front Suspension Kit is for the driver who feels the biggest problem at corner entry and through the first half of the corner. When a stock-based front end gets vague under braking, rolls too far onto the outside tire, or stops giving you confidence once grip goes up, the issue usually isn’t just spring rate or shock valving. The architecture itself is asking you to work around it.
Apex Engineered moves the front of the car from the original strut-based arrangement to a double A-arm layout and gives you adjustment for roll center, anti-dive, camber, caster, and toe. Those changes matter because they affect the things you actually feel: how quickly the nose responds when you turn in, how stable the car stays when trail braking, and how much control you have over the contact patch once load builds.
The front kit also leaves room for the build to evolve. It works with the factory front spindle through the supplied adapter, and it can also be configured for a 370Z front spindle if you want a more current bolt-in wheel-bearing solution. Wider tire fitment is part of the value too, but the bigger point is that the front kit gives the S30 a front suspension package that can finally support the rest of the car instead of holding it back.
The S30 TRACK ATTACK Rear Suspension Kit is the right answer when the back of the car is the part making you hesitate. If you’ve noticed the rear of the chassis feels too soft in its control, too questionable under power, or too dependent on aging factory pieces that were never meant for the tire and torque now in the car, that’s the sign to stop thinking only about alignment and start thinking about structure.
The rear kit solves a much bigger problem than rear ride height or camber alone. Apex Engineered replaces the factory mustache bar and dog legs with a dedicated rear subframe, converts the rear to a double A-arm arrangement, and gives you adjustment for roll center, anti-squat, camber, caster, and toe. That matters because the rear of the car stops feeling like a part you have to protect and starts feeling like a part you can trust.
The driveline path is just as important. The rear kit supports a Nissan 370Z differential upgrade and modern 370Z CVs in place of weaker factory stub axles and half-shafts and include 300M rolled-spline axles tested beyond roughly 1,000 ft-lb of torque. Those details tell you exactly who this kit is for: builders who are serious enough to fix the rear of the chassis the right way before it becomes the thing limiting the rest of the build.
The S30 TRACK ATTACK Complete Suspension Kit is for the owner who already knows the front and rear problems are connected. If the front of the car still won’t give you the response you want, the rear still feels like a liability, and you’re headed toward more tire, more brake, or more engine, solving one end at a time usually just stretches out the compromise.
For that build stage, a S30 Track Attack upgrade works best as the full system. Apex Engineered combines the front suspension conversion, the rear subframe system, and the broader adjustment range into one package with control over roll center, anti-dive, anti-squat, camber, caster, and toe, plus the wider-tire capacity that the original strut layout struggles to support. The full kit matters because it raises the ceiling of the whole chassis instead of improving one half while the other half still limits how far you can go.
That changes how the car develops from here. Instead of stacking more parts onto a foundation that still needs help, you start with a package that supports future wheel, brake, aero, and power choices from the beginning. That’s another reason S30 Track Attack exists in complete form: some builds are already past the point where partial fixes make financial or performance sense.
There isn’t one correct Track Attack upgrade entry point for every S30, and that’s exactly why this lineup works. The front kit is for the driver who wants the nose of the car to finally respond the way it should. The rear kit is for the builder who knows the back of the chassis and driveline need to catch up. The complete kit is for the owner who wants to stop splitting the answer into phases.
Viewed that way, S30 Track Attack upgrades are less about buying a catalog item and more about choosing the right fix for the issue your car is actually showing you on track. Once you identify where the chassis is asking for help, the right Track Attack kit gives you a much more serious platform to build from.
