How to Install and Tune an Adjustable Suspension on a Nissan GT-R?

April 4, 2024

When it comes to enhancing the ride quality and handling of your Nissan GT-R, an adjustable suspension is the way to go. This high-performance modification offers you the ability to customize your car’s suspension settings to your specific driving needs. Whether you’re looking for a smoother ride on the road or sharper handling on the track, an adjustable suspension will give your GT-R that much-needed edge. This article will guide you through installing and tuning an adjustable suspension for your Nissan GT-R.

1. The Importance of a Quality Suspension Kit

Before delving into the process of installation, it is crucial to understand the importance of a quality suspension kit. Suspension is more than just about the quality of your ride. It has a direct impact on the handling and performance of your car, especially when driving at high speeds or around tight corners.

A quality suspension kit primarily includes coilovers, which essentially are a type of suspension design where the shock absorber and the coil spring are assembled as a unit. With the right set of coilovers, you can easily adjust the ride height and stiffness of your GT-R. These adjustments can help optimize the car’s performance based on weight, speed, and road or track conditions.

The ideal kit for your Nissan GT-R should be lightweight, offer high damping ability, and come equipped with oil-filled shocks that can dissipate the heat generated during high-speed track runs. Therefore, take time to do research and choose a kit that will deliver top-notch performance.

2. Installing the Adjustable Suspension

Installing an adjustable suspension on your GT-R involves replacing the front and rear struts. Begin by securely lifting your car using a hydraulic jack. Remove the wheel and tire assembly to access the suspension system. Disconnect the sway bar end link and then the strut assembly by unscrewing the nuts at the top and bottom.

Next, install the coilovers from your suspension kit. Start with the front coilovers. They should be fitted into the strut tower and bolted securely at the top and bottom. Repeat the procedure for the rear coilovers. Once all the coilovers are installed, reconnect the sway bar end link, and finally reattach the wheel and tire assembly.

3. Tuning Your Suspension for Optimum Handling

Once the new adjustable suspension is installed, you’ll need to tune it for optimal performance. The key to this lies in finding a balance between ride comfort and handling characteristics.

Start by adjusting the ride height. Lowering your GT-R’s center of gravity will improve its handling capabilities, especially during high-speed cornering. However, be cautious not to lower it too much as it could result in poor ride quality.

Next, consider the damping settings. This adjusts the stiffness of the ride. A larger number will provide a stiffer ride, which is ideal for track use. A smaller number, on the other hand, will offer a smoother ride, suitable for daily driving.

4. Making Adjustments Based on Track Conditions

If you are planning to hit the track with your GT-R, you’ll need to adjust the suspension settings according to the track conditions. Harder settings can be beneficial for smoother tracks, while softer settings will be advantageous for rougher surfaces.

Adjustments can also be made based on the type of track. For instance, if the track has more high-speed corners, you can opt for a stiffer suspension to ensure better handling. Conversely, for a track with more low-speed corners, a softer suspension will be ideal to facilitate smoother turning.

5. Regular Maintenance of Your Suspension

Regular maintenance of your suspension system is as important as the installation and tuning process. This ensures that the system is always at its peak performance.

Regular maintenance includes checking the oil level and oil quality in the shocks. Over time, the oil can degrade, which can impact the shocks’ ability to dissipate heat, and therefore affect the performance of the suspension.

Also, keep an eye out for any signs of wear and tear on the suspension components. This can include leaks, corrosion, or other visible damages. Regular inspections and prompt replacements of worn-out parts will ensure that your suspension system continues to deliver top performance.

In conclusion, installing and tuning an adjustable suspension on your Nissan GT-R can significantly enhance your car’s handling and performance. However, remember that the key to achieving the best results lies in choosing a high-quality suspension kit, correctly installing and tuning it, and keeping up with regular maintenance. With these steps, you’ll be able to enjoy a smoother ride and sharper handling on both the road and the track.

6. Achieving Balance Between Body Roll and Anti-Roll Bars

In the world of gran turismo racing, the balance between body roll and anti-roll bars is critical. Body roll refers to the leaning effect your Nissan GT-R experiences when taking corners at high speed. It can adversely affect the car’s handling, especially when driving on track conditions.

On the other hand, anti-roll bars, also known as sway bars, are components in the suspension system that help reduce body roll. They work by distributing the force exerted on one wheel across to the other wheel. However, while anti-roll bars help in reducing body roll, setting them too rigid can affect the car’s ability to absorb bumps, leading to a harsh ride.

When tuning your adjustable suspension, you should find a balance between reducing body roll and maintaining a comfortable ride. Adjust the anti-roll bars as per your riding conditions. If you’re driving on a smooth street or track, you can afford to stiffen the bars a bit for better handling. Conversely, if you’re driving on rough surfaces, you should loosen them a bit for better ride comfort.

In essence, understanding and adjusting the interaction between body roll and anti-roll bars can dramatically improve the handling and ride quality of your Nissan GT-R.

7. Understanding the Impact of Price, VAT, and Top Mounts on Suspension Setup

When it comes to installing an adjustable suspension on your Nissan GT-R, cost can often be a significant factor. While it is crucial to invest in a high-quality suspension kit, the price and VAT should be within your budget. Remember, the higher the quality of the suspension kit, the better the ride quality and overall performance of your car.

Top mounts are another often overlooked aspect of the suspension setup. These components connect the suspension struts to the car body, aiding in absorbing shocks and reducing noise. Investing in high-quality top mounts can improve the overall durability and performance of your GT-R’s suspension system.

While it is tempting to save money by opting for cheaper alternatives, remember that the performance and longevity of your GT-R’s suspension system rely heavily on the quality of these components. So, while considering the price and VAT, do not compromise on the quality of the suspension setup.

Conclusion

In the realm of motorsport and car tuning, the Nissan GT-R holds a revered position. Renowned for its speed and handling, this car can be taken to even greater heights with an adjustable suspension system. But the process involves more than simply buying a suspension kit and installing it. It requires a deep understanding of the various components and how they interact.

From selecting a high-quality coilover kit to achieving the perfect balance between ride height and body roll, every step plays a pivotal role in enhancing the GT-R’s handling and performance. Maintenance, too, should never be overlooked.

While the process can be complex, forums general discussions and advice from forum members can offer valuable insights. They can provide tips and tricks based on their personal experiences, which can be particularly helpful for first-timers.

In essence, installing and fine-tuning an adjustable suspension on a Nissan GT-R is both an art and a science. It’s about understanding the car’s dynamics, your driving needs, and how best to meld the two together. With patience and perseverance, you can transform your Nissan GT-R into a true street and track performer.
