In stock for the 2015-2021 Subaru WRX STI, Eibach PRO-KIT performance springs deliver upgraded performance and ride comfort using our progressive spring technology. By lowering the Center of Gravity (CoG) the PRO-KIT increases steering response and improves vehicle dynamics for a sportier, more balanced feel.
