How to Use TOPair Air Struts Kit: Complete Guide

Step 1: Initial Setup and Installation

Installing this kit is a direct bolt-on process. You will need to safely jack up the vehicle and support it on jack stands. Remove the factory shocks and springs. The TOPair struts slide right into place. Secure the upper mounts to the chassis, then tighten the lower brackets. Run the air line from each strut to the tank and controller. Connect the compressor to the tank and wire the controller to the battery using the included power wire and fuse. The push-to-connect fittings make air line routing straightforward. No special tools are needed for the air fittings; just cut the line cleanly and push it into the fitting until it clicks.

Step 2: First-Time User Guide

After installation, power on the VITAL controller. The RGB display will light up. Download the AccuAir e+ Connect app on your smartphone. Pair the controller via Bluetooth 5.0. The connection is stable and instant. You will need to set your initial target pressures. Start with the recommended pressures provided in the manual. The system will automatically fill the tank to reach your desired ride height. The app interface is intuitive, showing pressure readings for each corner. You can save presets for different ride heights, such as Drive, Show, and Park.

Step 3: Core Functions and Daily Use

Daily use is simple. With the press of a button on the app or the physical controller, you can raise or lower the vehicle. For regular driving, set a moderate height that provides good ground clearance and comfortable ride quality. The system holds pressure reliably. The Bluetooth range is excellent, so you can adjust the suspension from outside the vehicle. The ride-height-on-start feature ensures the car returns to your preset height automatically when you start the engine. This is a huge convenience for daily driving.

Step 4: Advanced Techniques

Advanced users can fine-tune the individual corner pressures to achieve a perfectly level stance. The app allows for granular adjustments. You can also use the RGB backlight customization to match your interior or exterior lighting. The over-the-air updates mean your system will stay current with the latest features and bug fixes. For show purposes, you can program a specific sequence of height changes to impress spectators.

Step 5: Maintenance and Care

Maintenance is minimal. Periodically check all air line connections for leaks using soapy water. Ensure the compressor intake is clear of debris. Drain the water trap on the tank every few months to prevent moisture buildup. Keep the strut bodies clean to avoid dirt buildup on the seals. The electroplated finish resists corrosion, but it is still good practice to wash the underside of the car regularly.

Step 6: Troubleshooting Common Issues

If the system slowly loses height, check for leaks at the fittings. Tighten or replace the fitting if needed. If the compressor cycles on frequently, check for a leak in the air line or a loose connection. If the controller is not connecting to the app, ensure Bluetooth is enabled on your phone and try re-pairing. For any persistent issues, the manufacturer provides excellent support.

Performance & Real-World Testing

Testing Methodology

We installed this kit on a 2005 Nissan 350Z and drove it for three weeks across a variety of conditions. Our testing included daily commuting on rough city streets, highway cruising at 70 mph, and spirited driving on winding back roads. We also tested the system at a car show, adjusting the height frequently to simulate show use. We measured ride quality subjectively and objectively by noting noise, harshness, and overall comfort.

Performance Metrics

The ride quality at normal driving height is impressively compliant. It soaks up bumps and potholes much better than static coilovers set to a moderate stiffness. The damping is well-tuned for the 350Z’s weight. There is no excessive bouncing or wallowing. At the lowest setting, the ride is still acceptable for smooth roads, though you will feel sharper impacts. The system holds pressure consistently; we did not observe any significant drop in height over a week of daily driving. The Bluetooth connection never dropped, and the app responded instantly to height adjustments.

Real-World Scenarios

On the highway, the car feels planted and stable. The ability to lower the car at speed for better aerodynamics is a nice touch, though we recommend keeping a moderate height for safety. On rough roads, the air suspension provides a much more forgiving ride than coilovers. We drove through a construction zone with multiple potholes, and the system absorbed the impacts without jarring the cabin. At the car show, the ability to slam the car to the ground and then raise it back up with a single tap on the phone was a crowd-pleaser. The system was quick enough for frequent adjustments during the event.

Claims vs. Reality

The manufacturer claims on-the-fly ride height adjustment independent of spring pressure. This proved true. The adjustable lower mounts allow you to set the static height, and the air pressure then controls the dynamic ride. The claim of maximum corrosion resistance is also valid; after three weeks, including rain and road grime, the struts showed no signs of rust. The system delivered on its promise of being a complete, bolt-on solution. The only gap we noticed was that the instructions could be more detailed for first-time installers, but the system itself is well-designed.

Pros and Cons

What We Loved (Pros)

• Exceptional Ride Quality: The air suspension offers a smooth, compliant ride that rivals luxury vehicles. It is significantly more comfortable than most aftermarket coilovers.

Expert Tips for Maximum Value

Tip #1: Use Threadlocker on Mounting Bolts

Apply a medium-strength threadlocker to all suspension mounting bolts. This prevents them from loosening over time due to vibration. It is a simple step that adds long-term reliability.

Tip #2: Mount the Tank Vertically

Mounting the 4-gallon tank vertically helps with water drainage. The water trap can collect moisture more effectively, reducing the risk of freezing or corrosion inside the tank.

Tip #3: Pair with a High-Quality Air Line

While the included air line is good, consider upgrading to a braided stainless steel line for the hardest-to-reach connections. This adds durability and a professional look. You can find compatible accessories for air suspension online.

Tip #4: Calibrate the Controller After Installation

After installing, run the calibration routine in the AccuAir app. This ensures the pressure sensor readings are accurate, giving you precise control over ride height.

Tip #5: Set a Daily Driving Preset

Program a specific preset for daily driving that balances ground clearance with ride comfort. This saves time and ensures consistent performance.

Tip #6: Check Pressures Weekly

Take a few seconds each week to check the system pressure from the app. Early detection of a slow leak can prevent major issues down the road.

Tip #7: Use the RGB Backlight as a Pressure Indicator

Customize the RGB backlight color to change based on ride height or pressure. For example, set green for normal, yellow for low, and red for critical. This visual cue is helpful at a glance.

Common Mistakes to Avoid

1. Mistake: Overtightening the air line fittings. Solution: Hand-tighten the fittings plus a quarter turn with a wrench. Overtightening can damage the O-ring and cause leaks.
2. Mistake: Routing air lines near exhaust components. Solution: Plan your air line routing carefully, ensuring they are at least 6 inches away from any heat source. Use heat-resistant sleeves if necessary.
3. Mistake: Failing to secure the air tank properly. Solution: Use the provided mounting brackets and bolts to firmly secure the tank. A loose tank can shift during cornering, causing damage.
4. Mistake: Ignoring the compressor air filter. Solution: Check and clean the compressor intake filter regularly. A clogged filter reduces performance and can overheat the compressor.
5. Mistake: Setting ride height based solely on visual appearance. Solution: Use the adjustable lower mounts to set the mechanical height first, then use air pressure for fine-tuning. This maintains proper suspension travel.

Pricing & Where to Buy
