Tein 05-07 Subaru WRX STI (GDFD) Street Advance Z Coilovers

If you're looking to dial in the suspension on your 2005-2007 Subaru Impreza WRX STI, the Tein Street Advance Z coilovers are a solid option. These are designed to replace your factory struts and springs, giving you the ability to adjust both the ride height and the damping force. This means you can fine-tune your car's handling for everything from daily driving to track days.

Tein has built these coilovers with their advanced Advance Z technology, which uses a twin-tube system for consistent damping performance. The damping force can be adjusted across 16 different levels, allowing for a wide range of tuning possibilities. You can lower your car's center of gravity for better cornering grip and a more aggressive stance. The spring rates are carefully selected to offer a good balance between sporty handling and reasonable comfort for street use. The lower bracket is adjustable, giving you more flexibility in setting your ride height without sacrificing suspension travel. These are built with durable materials to withstand the rigors of daily driving and spirited use.

When installing these coilovers, you'll be replacing your entire strut and spring assembly. It's a good idea to have a torque wrench and the proper tools on hand. Since these are adjustable, you can experiment with different settings to find what works best for your driving style and road conditions. For the best results, consider getting a professional alignment after installation to ensure your tires wear evenly and your steering is precise.
