Luxury meets performance — that was Infiniti’s promise with the G37S. But beneath the comfort and refinement lies a chassis begging to be sharpened. Coilovers make that transformation possible, taking your G37 from comfortable cruiser to corner-carving precision machine.
Why Coilovers Are the Most Transformative G37S Upgrade
The G37S already comes with a capable suspension, but factory dampers and springs were built for mass-market comfort. Coilovers allow you to change that — giving you control over how your car rides, handles, and feels on the limit. They’re not just for looks; they’re a dynamic tool for performance and precision.
Whether you’re attacking mountain roads, tracking your car on weekends, or perfecting your drift angle, coilovers redefine how your G37S communicates with the road beneath you.
Layman’s Terms: What Coilovers Do and Why They Matter
Think of coilovers as adjustable muscles for your suspension. They combine the spring (which holds the car up) and the damper (which controls motion) into a single unit — one you can fine-tune for your exact driving style. You can make your G37S stiffer for sharper cornering, softer for comfort, or balanced for everyday use.
Factory shocks are like a one-size-fits-all shoe. Coilovers are like custom-fitted racing boots. Every adjustment — height, damping, rebound — lets you sculpt how the car moves and reacts.
The Technical Deep Dive: How Coilovers Enhance G37S Performance
1. Ride Height Adjustment
Stock suspension height limits your ability to tune aerodynamics or lower your center of gravity. Coilovers use threaded bodies to allow precision lowering, improving cornering grip and stability. Lowering also reduces body roll and increases chassis response.
2. Damping and Rebound Control
Damping is the speed at which the shock absorber compresses and rebounds. High-quality coilovers give you adjustable damping — allowing you to control how fast or slow your suspension reacts to bumps or weight transfer. This is key for fine-tuning the G37’s balance between comfort and control.
3. Spring Rates and Chassis Balance
- Street setup: 8kg front / 6kg rear
- Track setup: 10kg front / 8kg rear
- Drift setup: 12kg front / 10kg rear
These rates provide a baseline for grip, responsiveness, and stability. Stiffer springs increase precision but can make the ride harsh if not paired with proper damping.
4. Monotube vs Twin-Tube Design
The G37 benefits most from monotube coilovers, which dissipate heat better and offer faster damping response. Twin-tube designs are smoother and quieter — ideal for comfort builds or daily driving. SLRspeed’s monotube coilovers use motorsport-grade pistons and seals for durability under high load.
Setting Up G37S Coilovers for Different Driving Styles
Drift Setup
A G37S drift setup requires quick steering feedback and controlled weight transfer. Set front damping stiffer for precise initiations and keep the rear slightly softer to maintain traction through long slides. Lower the rear ride height slightly for better rotation and use around -3° front camber.
Track Setup
For track builds, balance is everything. Aim for a 25–35mm ride height drop, -2.5° front camber, and -1.5° rear. Adjust damping to mid-range to balance control and compliance. Proper corner balancing is essential — uneven weight distribution can cause unpredictable oversteer.
Street Setup
Daily drivers should prioritize comfort without losing response. Softer damping, moderate lowering, and balanced spring rates maintain a sporty feel without punishing your back. A -1.5° front / -1° rear camber setup is perfect for spirited street driving.
Suspension Geometry and the G37’s Hidden Potential
The G37’s double-wishbone front and multi-link rear suspension give it incredible mechanical grip potential — if set up correctly. Coilovers let you fine-tune roll center, bump steer, and camber curves to match your driving style.
When paired with adjustable control arms and sway bars, you can dial in track-spec precision or drift-friendly fluidity. The difference in steering feel and tire wear is night and day.
Coilovers vs Stock G37S Suspension – Real-World Differences
| Feature | Stock Suspension | Coilover Upgrade |
|---|---|---|
| Ride Height | Fixed | Fully Adjustable |
| Damping Control | Pre-set factory values | 24–32 Click Adjustable |
| Cornering Stability | Moderate | High – Tunable roll and weight transfer |
| Durability | Comfort-oriented | Track-proven construction |
| Camber Adjustability | Limited | Full top mount and arm compatibility |
Common Questions About G37S Coilovers
- Do coilovers make the ride harsh? Not if properly tuned. Quality coilovers balance comfort and control better than factory shocks.
- Will lowering affect tire wear? Only if geometry is left uncorrected. Use adjustable arms to maintain alignment.
- Are coilovers good for daily driving? Absolutely — monotube designs with adjustable damping can ride smoother than factory sport suspensions.
- Do I need corner balancing? Yes, for best results. It equalizes weight across tires for consistent grip and braking.
Coilover Maintenance Tips for Longevity
Keep threads clean and apply anti-seize periodically. Avoid pressure washing seals and inspect for leaks every oil change. Quality coilovers like SLRspeed’s are anodized for corrosion resistance and can last for years with simple upkeep.
