Which ones are really better? I have been looking into both, and don't know if there is much of a difference. How much lowering can these take? I was looking at Eibach sportlines, and they drop the car from 1.75-2.25 inches. I'm gessing that they can take this, but will I have other problems if I go this low. I will obviosly be getting camber correctoin with that. What if I only lower it 1-1.5 inches? Do I still need front and rear camber correction? What about ground control coil-overs? I would like to raise my car up a little in the winter, for obvious reasons, and have heard that these are the only decent coil overs, that arent "true" coil overs. But wouldn't I need to adjust the camber every time I changed ride height? Thanks for the help guys.
