The Infiniti G37S is one of the most underappreciated performance platforms of the late 2000s and early 2010s. With its strong VQ37VHR engine, refined interior, rear-wheel-drive layout, and robust chassis tuning potential, it offers an incredible blend of daily comfort and performance potential. But from the factory, the G37S suspension leaves a significant gap between what the chassis can do and what it is allowed to do.
This is where coilovers come in. By upgrading the G37S to a higher-quality, adjustable suspension system, the car immediately becomes sharper, more responsive, and more predictable. Whether you're building a canyon machine, a street-driven show car, a drift setup, or a dedicated weekend track car, coilovers are the foundation of the entire transformation.

Why Coilovers Matter So Much on the G37S Platform
The stock suspension on the G37S is comfortable and capable, but it is also soft, underdamped, and not adjustable in ways that matter for performance driving. When pushed aggressively, the car tends to roll more than ideal, transitions slowly between corners, and provides limited control over camber and ride height. Coilovers resolve all of these limitations.
Here’s what a coilover system adds:
- More immediate steering response
- Better body control through corners
- Reduced body roll
- Adjustable ride height for stance or performance
- Better weight transfer during acceleration, braking, and turning
- Access to adjustable damping settings
- Improved tire contact patch control
- Predictable chassis dynamics at the limit
These benefits apply equally whether the car is street-driven or track-focused. Most importantly, coilovers unlock the ability to tune the suspension system around your unique goals - something the stock suspension cannot provide.
How Coilovers Improve Steering and Chassis Feedback
Steering feel is one of the most noticeable improvements after installing coilovers. The G37S chassis responds dramatically to better damping and firmer springs. A well-tuned coilover setup will make steering inputs feel more direct and connected, giving the driver a sense of control that the stock suspension never achieves.
Why this happens:
- Less chassis flex due to reduced roll
- More linear steering rack behavior under load
- Improved feedback through the wheel
- Reduced mid-corner floating sensation
Once the springs and dampers begin working in harmony, the car starts to behave like a precision instrument rather than a luxury coupe.
Understanding Spring Rates for the G37S
Spring rates determine how stiff or soft the suspension feels. Higher rates reduce body movement and increase responsiveness, but require proper damping to maintain ride comfort. The G37S, being relatively heavy compared to a 350Z or S-chassis, typically benefits from slightly higher spring rates.
Common performance spring rates include:
- Front: 8k to 12k
- Rear: 6k to 10k
Track and drift drivers may run even higher rates depending on tire size, aero load, and driving style. The key is matching damping to the chosen rates so the ride is controlled rather than harsh.
Damping Adjustability and Why It Matters
Damping controls how quickly the suspension moves. Coilovers with adjustable damping allow you to fine-tune the response of the car to compression and rebound forces. This transforms how the G37S handles bumps, weight transfer, and quick transitions.
Good damping provides:
- Stable body control over uneven pavement
- Better grip in corners
- More confidence at high speed
- Reduced understeer and oversteer tendencies
If you plan to adjust settings frequently or drive in a wide range of conditions, adjustable dampers are one of the most valuable features of a coilover system.
Ride Height and Stance Tuning
The G37S responds exceptionally well to lower ride heights - but only if the suspension geometry is respected. Lowering the car too far without correcting alignment angles can hurt performance and tire wear. Coilovers allow precise ride height tuning without relying on factory springs or basic lowering springs, which offer no damping adjustment.
A good ride height target for performance is:
- Front: 1.0 to 1.5 inches lower
- Rear: 0.5 to 1.25 inches lower
This preserves suspension travel and minimizes bump steer while giving the car a more planted stance.
Why Camber Adjustment Is Critical for the G37S
The G37S gains significant handling improvements from camber tuning. Because the car is relatively heavy and does not naturally maintain perfect tire contact mid-corner, coilovers help dial in proper static camber.
Recommended performance camber:
- Front: -2.0° to -3.0°
- Rear: -1.2° to -2.0°
For drift setups, front camber may increase slightly, while rear camber often decreases to maximize the rear tire’s contact patch.

Daily Driving vs Track vs Drift Tuning
Daily Driving Setup
- Moderate spring rates
- Softer damping
- Minimal camber
- Comfort-focused ride height
Track Setup
- Stiffer spring rates
- Medium-fast rebound
- Higher camber values
- Lower ride height with geometry in mind
Drift Setup
- Stiffer rear springs
- Fast rebound for weight transfer
- Front camber for turn-in sharpness
- Higher rear ride height for rotation
Each discipline requires different weight transfer behavior. Coilovers allow the G37S to mold itself to the driver's needs.
Why Coilover Quality Matters
The G37S platform benefits more from high-quality coilovers than many other cars because the chassis is both powerful and heavy. Low-quality coilovers often fail quickly, ride poorly, or fade under heat. Quality units offer:
- Proper damping matched to the car’s weight
- Corrosion-resistant hardware
- Consistent performance across temperature changes
- Reliable seals and long-term durability
- Predictable handling
Inferior coilovers may look appealing due to low cost but often provide poor real-world performance. Investing in quality suspension ensures the car handles correctly and safely.
Conclusion: Coilovers Redefine What the G37S Can Do
Upgrading to coilovers is one of the most transformative modifications you can make to the Infiniti G37S. The improvements to steering response, cornering stability, weight transfer, ride quality, and overall chassis behavior are dramatic.
