The Progress Technology CS3 coil-over kit for 1989–1991 Honda Civic, Si and CRX is a Coil-Over 3 system with rebound-adjustable dampers matched to a 550 lb/in front spring and 450 lb/in rear spring for a stiffer front bias. Lowering height is adjustable from 1" to 3" and the kit uses the factory top hat. CS3 expands spring-rate choices across fourteen combinations so you can set up for track, drag, or a smoother street ride and dial rebound for road quality.
