Tein 15-21 Subaru WRX STI (VAG/VAF) Street Advance Z Coilovers

If you're looking to dial in the handling and stance of your 2015-2021 Subaru WRX STI (VAG/VAF), the Tein Street Advance Z coilovers are a solid option. These are designed to give you a noticeable improvement in cornering grip and a more aggressive look without sacrificing too much ride comfort for daily driving. They replace your factory struts and springs, offering a complete suspension upgrade in one package.

Tein has built these coilovers with their advanced damping technology to provide a responsive feel on the road. They feature a full-length adjustability system, meaning you can lower your car to achieve that perfect stance, and the spring rates are carefully selected to balance performance with street drivability. The internal construction uses durable materials to ensure longevity, even with regular use. You'll find that the ride quality is firm and controlled, which helps reduce body roll during spirited driving and cornering, making your STI feel more planted and predictable.

This kit includes all four corner units, ready for installation. While they are designed as a direct replacement for your stock suspension components, it's always a good idea to have your alignment checked after installing new coilovers to ensure optimal performance and tire wear. These coilovers are a popular choice for WRX STI owners looking for a significant upgrade in suspension performance and adjustability.
