Buying Guide for Infiniti G37 Coilovers
The selection of coilovers for your Infiniti G37 should depend on multiple factors, including driving style, suspension goals, and compatibility considerations. Here are key points to evaluate before making a purchase:
Compatibility and Model Fitment
Verify that the coilover kit fits your specific Infiniti G37 model year and type (Coupe, Sedan, RWD, with or without 4-wheel steering). Most kits specify exact model compatibility, as different G37 trims may require tailored suspension setups.
Damping Adjustment Levels
Coilovers offering a wide range of damping levels provide flexibility to tune the suspension stiffness for street or track use. Higher numbers of damping adjustments (e.g., 32+ levels) tend to allow finer tuning but may add complexity to setup.
Spring Rate Considerations
Spring rates affect ride comfort and handling balance. Stiffer springs improve cornering and reduce body roll but may decrease ride comfort. Choose spring rates matching your preferred driving environment—street driving often benefits from moderate rates, while track use demands stiffer springs.
Ride Height Adjustability
Adjustable ride height coilovers enable lowering the vehicle to improve the center of gravity for better handling and aesthetics. Ensure the kit provides sufficient height adjustment range and consider the effect of lowered suspension on daily driving clearance and alignment.
Build Quality and Components
Look for mono-tube shock designs and corrosion-resistant materials such as anodized aluminum or powder-coated mounts. Durable construction ensures longevity and safer performance under varied driving conditions.
Application and Driving Needs
Evaluate whether you need coilovers optimized for comfort, street performance, or racing. Kits like maXpeedingrods offer multi-level damper settings for different scenarios, while others specialize in either street or track focus.
Additional Features
Features such as top mounts for camber adjustments, ease of damper knob adjustment, and included warranties can influence the overall user experience. These details may improve fine-tuning and maintainability of your suspension system.
