CRX undertray

What you're probably talking about are parts like #6 & #9 below...



They're kinda extensions of the fender liners and do extend under portions of the motor/trans, but are definitely not attached to the suspension itself. Given the problems getting any cool air to the front brakes (even when using ducts), most of us remove as much of that stuff as possible.
