Check Out this Website with the Part Numbers and other info.

The springs you are selling are Neuspeed Sports (55.07 as shown on the springs) are for a 1989 - 1991 Civic/CRX application with a 2 inch drop in the front and 1.8 inch in the rear. Yeah they may fit other Hondas, but the spring rate is different and when installed on heavier cars will cause to drop to be beyond listed and cause a bouncier ride.

These won't work for my Integra...wish they would...Sorry Man.
