My Honda Accord 92, aka "Ghetto Rice," has some Eibach Pro Springs installed on it. I want to make it even lower and I was wondering, are the Eibach Pro Springs adjustable or do I have to switch it out completely? What exactly are coilovers? I heard those are adjustable (aka Ground Control). Is there anything that I can add to my existing springs to make it lower? Or do I just have to settle for coilovers?
