Specifications
Part Details:
The IAG Spec Street Series Coilovers by Fortune Auto are designed to enhance handling, ride quality, and suspension adjustability for the 2015–2021 Subaru WRX and STI. Engineered for street-driven performance vehicles, this suspension package delivers improved control and responsiveness while preserving the comfort needed for daily driving.
Developed in partnership with Fortune Auto, these coilovers feature chassis-specific valving tuned to IAG’s street-focused specifications. Compared to the factory suspension, drivers can expect reduced body roll, improved cornering stability, and more predictable road feedback—without the harsh ride commonly associated with track-oriented coilovers.
Street-Focused Performance Tuning
The damping characteristics of the IAG Spec Street Series Coilovers are optimized for real-world driving conditions. They are designed to absorb uneven road surfaces smoothly while remaining composed during spirited driving, making them well suited for daily use, weekend canyon driving, and performance street builds.
This balanced tuning allows WRX and STI owners to improve handling and appearance without sacrificing drivability or comfort.
Ride Height & Adjustability
Ride height is fully adjustable, allowing drivers to fine-tune vehicle stance and suspension geometry to match their preferences. Proper adjustment can help reduce wheel gap, improve handling balance, and enhance overall vehicle aesthetics while maintaining usable suspension travel.
