Tein 06-10 Infiniti M35/M45 (Y50) Flex Z Coilovers

What you get with this Tein Flex Z coilover kit are complete front and rear assemblies, ready to bolt onto your 2006-2010 Infiniti M35 or M45. These aren't just lowering springs; they're full coilover units that replace your entire strut and spring setup. This means you can dial in both the ride height and the damping force to get the exact look and feel you want for your Y50 chassis.

Tein designed the Flex Z series to offer a wide range of adjustability without breaking the bank. You can lower your M35 or M45 significantly, and with 16 levels of damping adjustment, you can fine-tune the stiffness to match your driving style, whether you're cruising daily or hitting some spirited drives. The internal construction uses a twin-tube system, and they're built with durable materials to handle the demands of everyday use while providing a noticeable improvement in cornering and body control. The spring rates are carefully selected to work well with the vehicle's weight, offering a balance between comfort and performance.

When installing these, you'll be replacing your stock struts and springs, so it's a good idea to have a solid understanding of suspension work or have a trusted mechanic handle the job. Because you're adjusting ride height and potentially changing suspension geometry, a professional alignment after installation is highly recommended to ensure proper tire wear and handling characteristics. This kit is a popular choice for M35 and M45 owners looking to give their car a more aggressive stance and a more responsive feel on the road.
