To improve the look and handling of the Subaru WRX STI, Agency Power has developed these performance racing springs. These lowering springs are designed to work with the factory struts on the 2008 and up GH and GE chassis of the Subaru WRX and STI. Agency Power has worked to get a spring rate that gives the car an amazing ride quality on the street, yet able to push limits on the track. The springs lower the car approximately 1.25 inches in the front and 0.75 inches in the rear for a good clean stance. The springs are finished in a white powder coat which will match our Agency Power sway bar kits. The springs are sold as a complete set for the front and rear of your vehicle.
