Lower Control Arm, basically the lower arm on the suspension that the bottom of the shock actually attaches to. Most of the bushings on the ES kits are for those arms, front and rear. Here's a pic of mine from my '92 CX (this is a GS-R rear arm)



I just had that pic online anyway. The grease fittings I added when I installed the bushings to keep them from sqeeking but I never actually did grease them (car was wrecked a few months later). Those bushings in the front and rear are where most of an ES kit goes in a Honda suspension. I've never owned a CRX so I'm not familar with it's exact layout but I'm assuming it's simliar. If you're using the Integra suspension arms, go with an Integra kit (most likely the bushings are the exact same anyway).
