Tein 05-07 Subaru WRX STI (GDF D/E) Flex Z Coilovers

If you're looking to dial in the handling and stance of your 2005-2007 Subaru WRX STI (GDF D/E chassis), the Tein Flex Z coilovers are a solid option. These units replace your factory struts and springs, giving you the ability to adjust both ride height and damping force to suit your driving style, whether you're hitting the track or just want a more controlled feel on the street. They are built with Tein's experience in motorsports to offer a significant improvement over stock suspension components.

The Flex Z series uses a twin-tube internal structure, which is known for its smooth damping characteristics and reliability. They feature a full-length adjustment system, meaning you can lower the vehicle without sacrificing suspension travel, a common issue with simpler coilover designs. The damping force can be adjusted across 16 levels, allowing for fine-tuning of your car's ride and handling. These coilovers also incorporate Tein's advanced Lower Height Adjustment system, which allows for independent adjustment of ride height and spring preload, ensuring you can achieve the perfect setup without compromising suspension geometry. The internal bump rubber and dust boots are included to protect the shock absorber from debris and impact, contributing to their longevity.

When installing these coilovers, you'll find they are designed to fit directly onto your WRX STI, making the swap from your stock suspension straightforward. While they are a complete assembly, it's always a good idea to have a professional alignment done after installation to ensure optimal handling and tire wear. These coilovers are a well-built package that offers a wide range of adjustability for drivers who want to take their Subaru's performance to the next level.
