What’s the Most Effective Way to Tune the Suspension Damping on an Acura NSX for Track Days?
As car enthusiasts, you likely understand the significance of a finely tuned suspension system. It is the key to a smooth, high-speed ride, especially for those who enjoy track days. The Acura NSX is one of those cars that not only likes speed but also has a suspension system that is highly responsive to tuning. In this article, we delve deeper into the subject of how to tune the suspension damping on an Acura NSX for track days.
Understanding the Acura NSX Suspension System
Before delving into the tuning process, it is essential to grasp the structure and functioning of the Acura NSX’s suspension system. The NSX features a sophisticated double-wishbone suspension both in the front and the rear, boasting coilovers that allow for a wide range of adjustments.

The NSX’s suspension is designed to handle the car’s high torque and power output, providing stability at high speeds. Its low and wide stance, combined with its mid-engine layout, gives it excellent balance and handling characteristics on the track.
The front suspension has a significant impact on the car’s handling characteristics, while the rear suspension helps to manage the car’s power output effectively. Both front and rear suspensions feature coil springs and dampers, which can be adjusted to improve performance based on the driving conditions and driver preferences.

Importance of Suspension Damping
Suspension damping refers to the control of oscillation in the springs of a car’s suspension system. Damping is crucial because it converts the kinetic energy of the springs into heat, thus reducing the amount of bouncing and offering a smoother ride.
The NSX’s coilovers provide a good balance of comfort and performance, but they can be adjusted to provide improved handling and stability, especially in high-speed track situations. Fine-tuning your suspension damping can dramatically improve your NSX’s performance on the track, allowing for quicker lap times and a more enjoyable driving experience.
Adjusting Front Suspension Damping
When tuning the suspension damping for track use, it’s best to start with the front suspension. The front suspension is critical because it greatly affects the car’s turn-in response and stability under braking.
For track use, you usually want a stiffer front suspension to improve response and reduce body roll. This can be achieved by increasing the damping force of the front suspension. However, remember that a stiffer suspension will also transmit more road imperfections to the cabin, which may impact comfort.
Also, note that the damping setting will depend on the track layout. For example, a track with many high-speed corners may require a softer setting to maintain grip, whereas a track with tight corners and quick changes in direction may benefit from a stiffer setup.
Adjusting Rear Suspension Damping
After setting up the front suspension, it’s time to adjust the rear. The rear suspension plays a critical role in managing the NSX’s power and maintaining stability, especially when accelerating out of corners.
Just as with the front, the rear damping setting will depend on track conditions and personal preference. Generally speaking, a stiffer rear suspension will lead to oversteer, while a softer rear suspension will result in understeer.
For a more neutral handling balance, you may want to start with a similar damping setting to the front and adjust from there. Keep in mind that the NSX’s mid-engine layout means it naturally tends towards oversteer, so you may need to soften the rear damping slightly to ensure a balanced handling.
Again, don’t forget that track conditions will significantly influence your settings. On a rainy day, for instance, you might prefer a softer setup for better grip.
Trial and Error: The Key to Perfect Suspension Damping
The process of tuning suspension damping is not an exact science. It’s a delicate balance that requires a good understanding of your car, the track, and your driving style.
Remember that what works for one driver might not necessarily work for another. Also, what works on one track might not work on another. The key is to experiment with different settings, taking note of how each adjustment affects the car’s handling.
The NSX’s advanced suspension system offers an excellent platform for fine-tuning, providing a wide range of damping settings to suit different driving conditions. With patience and practice, you can find the perfect damping setting that will make your NSX a true track day sensation.
Don’t be discouraged if the perfect setup doesn’t come immediately. It’s all part of the learning process. The more you understand your car and the suspension system, the better you will become at adjusting it to match your needs on the track. Remember, the goal is to enhance your track day experience and improve your lap times, all while ensuring a smooth and stable ride.
The Impact of Lowering Springs, Ride Height, and Spring Rates on Suspension Damping
For the Acura NSX, lowering springs and ride height are crucial elements to consider when tuning the suspension damping for track use. These components significantly influence the car’s center of gravity, which directly impacts its handling characteristics.
Lowering springs reduce the ride height of the car, leading to a lower center of gravity. This adjustment can improve the car’s stability and responsiveness, especially in high-speed corners. However, it’s essential to remember that excessively lowering the ride height can result in a harsher ride quality due to reduced suspension travel.
The spring rate, which refers to the stiffness of the springs, is another significant factor to consider when adjusting the damping system. The spring rates in the Acura NSX are high, contributing to the car’s excellent handling and responsiveness. However, for track use, it may be beneficial to adjust these rates further.
For high-speed tracks with long, sweeping corners, a higher spring rate can help maintain stability and control. Conversely, for slower tracks with tight, twisty sections, a lower spring rate can improve grip and agility.
The key is to find the perfect balance between ride height, spring rates, and damping settings. This balance is not a one-size-fits-all setting, but rather it is influenced by factors such as the track layout, weather conditions, and personal driving style.
The Role of Front-Rear Balance and Wheel Drive Configuration in Suspension Damping
The Acura NSX’s mid-engine, rear-wheel drive configuration plays a significant role in its handling characteristics. It’s crucial to bear this in mind when adjusting the suspension damping settings for track use.
The mid-engine layout provides excellent balance, allowing for high-speed stability and agile handling. However, it also means that the car naturally tends toward oversteer, which is when the rear of the car swings out during high-speed cornering.
To counteract this tendency, it can be beneficial to soften the rear damping setting slightly, as we mentioned earlier. This adjustment can help to maintain a balanced handling characteristic between understeer and oversteer.
The NSX’s rear-wheel drive setup also plays a role in its suspension damping. This configuration allows for excellent power transfer to the road, especially when accelerating out of corners. However, it also puts significant strain on the rear suspension, making the damping settings crucial for maintaining control and stability.
Conclusion: Perfecting Your Acura NSX Suspension Damping for Track Days
In conclusion, tuning the suspension damping on an Acura NSX for track days requires a deep understanding of the car’s suspension system and a willingness to experiment. The process involves adjusting the damping settings on both the front and rear suspensions, taking into account factors such as the track layout, weather conditions, and personal driving preferences.
Additionally, it’s crucial to consider other components such as lowering springs, ride height, and spring rates when adjusting the damping system. These elements significantly impact the car’s handling characteristics and can be fine-tuned to enhance track performance.
Lastly, remember the impact of the NSX’s mid-engine, rear-wheel drive layout on its handling. This configuration can contribute to a natural tendency towards oversteer, which may need to be compensated for when tuning the suspension damping.
With the right tuning, patience, and practice, your Acura NSX can be tweaked to offer an optimal balance of control, stability, and speed on the track. Happy driving, and may your NSX continue to bring you many thrilling track days ahead!
