G37S Coilovers Upgrade Guide – Drift, Daily, and Track Setup Explained

The Infiniti G37S has become a cult favorite among enthusiasts for its balance of luxury, power, and rear-wheel-drive handling. Whether you’re carving corners on the track, setting up a daily with perfect stance, or drifting at your local event, one upgrade can dramatically transform the car’s performance: coilovers.

In this ultimate guide, we’ll explore why G37S coilovers are the most impactful suspension upgrade, how to choose the right setup for your driving goals, and how to tune them for drift, grip, or street use.

⚙️ What Are Coilovers and Why the G37S Benefits Most

A coilover, short for “coil spring over shock,” is a suspension unit combining a spring and damper into one adjustable assembly. Unlike factory shocks and springs, coilovers allow fine-tuning of ride height, spring preload, and damping force. The result is total control over your G37’s behavior under cornering, braking, and acceleration.

The G37S comes from the factory with a solid suspension design—but it’s tuned for comfort and safety margins, not aggressive performance. Coilovers remove that limitation by allowing full suspension geometry control, improving grip and predictability across all driving conditions.

🏁 Benefits of Coilovers for the Infiniti G37S

• ✅ Adjustable ride height for perfect stance or track clearance.
• ✅ Custom damping settings for daily driving, drifting, or circuit performance.
• ✅ Improved cornering response and reduced body roll.
• ✅ Optimized tire contact under load and braking.
• ✅ Enhanced chassis feedback for better control at the limit.

With the right setup, coilovers make your G37 feel more direct, predictable, and confident through every turn.

🔩 Key Coilover Features to Look For

Not all coilovers are created equal. For the G37S, you want a setup that offers both performance tuning and reliability. Here are the critical factors to consider:

1. Monotube Dampers: Provide consistent damping and better heat dissipation—ideal for spirited driving and track sessions.
2. Spring Rates: Choose rates matched to your driving style. Drift setups often run higher front spring rates, while track builds favor balanced rates.
3. Camber Plates: Allow alignment adjustment for sharper turn-in and tire wear control.
4. Rebound/Compression Adjustment: Gives you control over how the suspension reacts to bumps and weight transfer.
5. High-Quality Materials: Anodized aluminum and corrosion-resistant coatings ensure longevity and precision adjustment over time.

📊 Recommended Coilover Spring Rates for G37S

These rates are a general baseline. The ideal setup depends on tire compound, power level, and driving surface. Professional tuners often make small adjustments to achieve the best balance.

🚗 Drift vs Track vs Daily Coilover Setup

The G37’s multi-link rear suspension provides great flexibility, but setup priorities differ drastically between driving styles. Here’s how to optimize coilovers for each discipline:

Drift Setup

• Front camber: -4.5° | Rear camber: -1.5°
• Front toe: 1/8” out | Rear toe: 1/16” in
• Front ride height: lower than rear for faster initiation
• Stiffer front damping for sharper response

Track Setup

• Front camber: -3° | Rear camber: -2°
• Balanced ride height
• Medium compression and rebound for stable grip
• Equal tire contact through cornering loads

Daily Street Setup

• Front camber: -2° | Rear camber: -1.5°
• Comfort-oriented damping (soft-medium)
• Moderate drop for clearance and aesthetics

🧠 Coilover Tuning Explained

Tuning coilovers is where the true performance gains appear. Three main variables affect your setup: ride height, damping, and alignment geometry.

• Ride Height: Lowering your G37 reduces its center of gravity but alters suspension geometry. Maintain balance between front and rear to prevent bump steer or poor weight transfer.
• Damping: Adjust compression to control body movement, and rebound to manage how fast the spring returns after compression. Start in the middle of the adjustment range and fine-tune from there.
• Camber & Toe: Use camber plates and adjustable arms to restore proper alignment after lowering. Too much camber reduces straight-line traction and increases tire wear.

⚖️ Monotube vs Twin-Tube Coilovers – Which Is Better for G37S?

Monotube coilovers are the preferred choice for G37S owners who drive hard. They provide quicker damping response and more consistent performance under heat. Twin-tube coilovers are typically softer and more forgiving for daily driving, but they can fade under track abuse.

For those balancing both comfort and performance, SLR’s Drift Spec Coilovers deliver the best of both worlds—offering motorsport-level damping precision without sacrificing daily usability.

🔧 Installation Tips for G37S Coilovers

1. Inspect all bushings, control arms, and end links before installation—worn parts affect alignment accuracy.
2. Torque bolts with the suspension loaded (at ride height) to prevent bushing preload.
3. After installation, always perform a full alignment with camber, caster, and toe correction.
4. Check coilover t
