I'm confused , what does Eibach have to do with Ground Control? If you like Eibachs then why not just get the eibachs .Mr. Bigs said:Since Eibach is suppose to be one of the premier manufacturers of lowering springs I plan to go with Ground Control springs. Ground Control has a adjustable spring set-up that will allow you to adjust the height of your car to your liking. The set-up cost a little more than a regular spring and strut set-up does but, being able to adjust the height of my car more than makes up for the difference in the long run. I can give my car a really low stance for shows, during winter I can raise it to help combat those really snowy days and then I can adjust it when spring comes to the height I like for everyday use. So your see having an adjustable spring set-up has its advantages.
