Tein 11-14 Subaru WRX STI (GRF/GVF) Flex Z Coilovers

If you're looking to dial in the handling and stance of your 2011-2014 Subaru WRX STI (GRF/GVF), the Tein Flex Z coilovers are a solid option. These are designed to give you a lot of control over your car's ride height and how stiff or soft the suspension feels, making them great for everything from daily driving to track days. They replace your factory struts and springs with a complete, integrated unit, simplifying the upgrade process.

Tein has built these Flex Z coilovers with a focus on providing a wide range of adjustability without breaking the bank. You can lower your STI significantly, often by several inches, to achieve that aggressive look or to fine-tune your center of gravity for better cornering. The damping force is adjustable across 16 different levels, allowing you to easily switch between a comfortable ride for the street and a firmer setting for spirited driving or track use. They also feature a full-length adjustment system, meaning you can set the ride height independently of the spring preload, which helps maintain proper suspension travel and ride quality even when you go very low. The internal structure uses Tein's advanced Advance Needle technology for precise damping control.

When installing these, you'll be replacing your entire strut and spring assembly. The kit includes all four coilovers. It's a good idea to have a professional alignment done after installation to ensure everything is set up correctly for your driving style and to maximize tire life. These coilovers are built to last, with durable construction designed to handle the demands of a performance vehicle like the WRX STI.
