Features
- Spring Rate: Front Spring rate: 12 kg/mm (672 lbs/in) & Spring rate Rear 10 kg/mm (560 lbs/in) with spring preload: 7-10 mm. Spring length Front: 183mm & Spring length Rear: 223mm; Coilover overall length Front: 397mm - 520mm & Coilover overall length Rear: 541mm - 626mm
- Twin-tube Structure: Compared to mono-tube construction, the twin-tube has a longer stroke and higher height adjustability, and they will give you a more comfortable riding experience by reducing the pressure on the joints and also minimizing friction, and ensuring sufficient travel with less effort.
- Functionality: Enhance steering performance and prevent cornering understeer and oversteer. Reduce cornering roll and improve braking performance, leading to shorter braking distances and increased driving safety. The coilover struts are easy to install with the proper tools.

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.
- Customizable Comfort: With adjustable damping and preload, you can fine-tune your ride for comfort on daily drives or performance on the track.
- Durability: Premium aluminum and steel construction resists wear and maintains consistent performance over time.
- Braking & Safety: Reduced roll and better suspension control can improve braking efficiency, helping you stop sooner and drive safer.
Switching to coilovers is not just about looks—it’s about transforming the way your Infiniti reacts on the road.
