I'm actually looking for coil overs to lower my car at least an inch.

I've looked everywhere I know for coil overs on a 96 Grand Am... found nothing.

If all you want is to lower it, you can get drop springs that will bring it down. I think I found some Eibach springs while searching.

I saw those also, but right now I'm on a limited budget and am trying to do this right as to not jeprodise anything.
