Tein 06-10 Infiniti M35 (Y50) Flex Z Coilovers

The Flex Z coilovers from Tein feature a full-length adjustment system, allowing you to set your ride height independently of the spring preload. This means you can lower your 2006-2010 Infiniti M35 (Y50) without sacrificing suspension travel or ride quality. The twin-tube internal structure is a well-known design for providing a comfortable ride on the street while still offering the control you need for spirited driving.

Tein has built these coilovers with their advanced Z.S.T. (Z. Speed Technology) damping force adjustment system, which gives you 16 levels of adjustment. You can easily dial in the suspension feel from soft and comfortable to firm and responsive. The upper mounts are typically included, often featuring pillow ball bearings for the front to improve steering response and a rubber mount for the rear to help isolate road noise. These coilovers are also designed to work with Tein's optional EDFC (Electronic Damping Force Controller) system, so you can adjust damping on the fly from inside your cabin if you choose to add it later.

When installing these, you'll find they are a direct replacement for your factory struts and springs. The full-length adjustment system means you can achieve your desired ride height by turning the lower bracket, and then set the spring preload to the manufacturer's recommendation. It's a good idea to have an alignment done after installation to ensure optimal handling and tire wear. These coilovers are a solid option for M35 owners looking to improve their car's stance and handling performance.
