Tein 2015 Subaru WRX STi Street Basis Z Coilovers

Tein is well-known for their performance suspension components, and the Street Basis Z coilovers are a solid option for your 2015-2020 Subaru WRX or WRX STi. If you're looking to lower your car and get a more responsive feel from the suspension, these coilovers are designed to do just that. They replace your factory struts and springs with a complete, integrated unit, making the installation straightforward.

These coilovers feature a twin-tube internal structure, which is a common and reliable design for performance dampers. The damping force is pre-set for a sporty feel that balances street comfort with improved handling. You can adjust the ride height using the included spring seats and locking collars, allowing you to dial in the stance you want without affecting the spring preload, which is important for maintaining proper suspension travel and ride quality. The lower bracket is also adjustable on some applications, giving you more flexibility in setting your ride height. They use Tein's durable EDFC (Electronic Damping Force Controller) system, which allows for on-the-fly damping adjustments from inside your car, though it's sold separately.

When installing these, you'll want to ensure you have the necessary tools for suspension work, and it's always a good idea to have your alignment checked after installation to get the most out of your new suspension setup. These coilovers are built to last and offer a noticeable improvement in how your WRX handles corners and responds to steering inputs.
