Agency Power has developed performance racing springs to improve the look and handling of the 08-10 Subaru STI. Agency Power has worked to get a spring rate that gives the car an amazing ride quality on the street while stilling being able to push the limits on the track. The springs will lower your STI approximately 1.25 inches in the front and 0.75 inches in the rear for a good stance that won't have you bottoming out in your driveway. The springs are powder coated white to match AP's sway bars. The springs are sold as a complete set for the front and rear.
Spring Rates: F: 250lb/in linear / R: 180lb/in progressive
Drop: Front: -1.25" / Rear: -.75"
