Eibach Pro-Kit Lowering Springs - Honda Civic Si (2017-2021)

The Eibach Pro-Kit lowers the 2017-2021 Honda Civic Si roughly 0.9" front and 1.1" rear (sedan), giving the car a purposeful rake while dropping the center of gravity for flatter cornering. Progressive spring rates trim squat, dive, and body roll and keep the factory-damper ride comfortable for daily driving. Set of four springs.
