The Nissan R35 GT-R is renowned for its incredible performance and handling capabilities. However, for enthusiasts looking to maximize their track day experience, upgrading the suspension can provide significant enhancements. This article explores the various options available for upgrading the R35 GT-R suspension to improve handling and overall performance on the track.
Understanding the Stock Suspension
The stock suspension of the R35 GT-R is engineered for a balance between comfort and performance. It features a multi-link setup with Bilstein dampers and an adjustable ride height. While this setup is effective for everyday driving, track enthusiasts may find limitations in terms of responsiveness and adjustability.
Benefits of Upgrading the Suspension
Upgrading the suspension on your R35 GT-R can lead to numerous benefits, particularly for track use. These enhancements can include:
- Improved Handling: Upgraded suspension components can provide better grip and cornering stability.
- Adjustability: Many aftermarket options allow for fine-tuning of settings to match specific track conditions.
- Reduced Body Roll: Stiffer springs and dampers can minimize body roll during aggressive cornering.
- Enhanced Feedback: A more responsive suspension setup can give drivers better feedback from the road.
Types of Suspension Upgrades
When considering suspension upgrades for the R35 GT-R, there are several types of components to explore:
- Coilovers: Adjustable coilovers allow for changes in ride height and damping settings, offering versatility for both street and track use.
- Sway Bars: Upgraded sway bars can reduce body roll and improve cornering performance.
- Strut Braces: These components can increase chassis rigidity, enhancing overall handling.
- Bushings: Upgrading to stiffer bushings can improve responsiveness and reduce unwanted movement in the suspension.
Choosing the Right Coilover System
When selecting a coilover system for the R35 GT-R, consider the following factors:
- Damping Adjustment: Look for coilovers with adjustable damping to customize the ride for different tracks.
- Spring Rates: Choose spring rates that match your driving style and the type of track events you participate in.
- Build Quality: Opt for reputable brands known for their durability and performance in motorsports.
- Installation Requirements: Some coilover systems may require additional modifications for proper fitment.
Installing Sway Bars
Upgrading sway bars is a relatively straightforward process that can yield significant handling improvements. Here’s what to consider:
- Front vs. Rear: Upgrading both front and rear sway bars can create a balanced handling characteristic.
- Bar Diameter: Thicker bars provide more stiffness, which can reduce body roll.
- End Links: Consider upgrading to adjustable end links for better performance and tuning options.
Enhancing Chassis Rigidity
Increasing chassis rigidity can lead to improved handling. Here are some methods to enhance the rigidity of your R35 GT-R:
- Strut Tower Braces: These braces connect the strut towers and reduce flex during cornering.
- Underbody Braces: Installing underbody braces can improve overall chassis stiffness.
- Roll Cages: For serious track use, a roll cage can provide maximum rigidity and safety.
Upgrading Bushings
Replacing factory rubber bushings with stiffer polyurethane or solid bushings can enhance responsiveness. Consider these points:
- Types of Bushings: Polyurethane bushings offer a good balance of performance and comfort.
- Installation: Some bushings may require pressing, so professional installation may be necessary.
- Longevity: Upgraded bushings often last longer than stock options, especially under track conditions.
Testing and Tuning Your Setup
Once you have upgraded your suspension, it’s crucial to test and tune your setup. Here are some tips:
- Track Testing: Take your GT-R to a track day to evaluate the performance of your new suspension setup.
- Adjustments: Make incremental adjustments to damping settings and ride height for optimal performance.
- Feedback: Pay attention to how the car responds to steering inputs and cornering forces.
Conclusion
Upgrading the suspension of your R35 GT-R can significantly enhance its handling capabilities for track days. By carefully selecting and installing high-quality components, you can create a setup that maximizes performance, responsiveness, and enjoyment on the track. Whether you are a seasoned driver or a newcomer to track days, these upgrades can transform your driving experience.
