Stock Suspension vs Coilovers for Infiniti G35, G37x, M35x, M45x
Upgrading to coilovers can greatly improve handling and performance for your Infiniti G35, G37x, M35x, or M45x AWD. Unlike stock suspension, which prioritizes comfort over precision, coilovers offer adjustable settings for better control, reduced body roll, and a more responsive driving experience.
- Enhanced Handling: Coilovers improve cornering stability and reduce body roll, giving your G37x or G35 sharper steering response.
- Adjustable Ride Height: Unlike stock springs, coilovers allow you to lower your vehicle 2"-4", improving aesthetics and center of gravity.
