I have a '99 3kgt, and I am seriously considering a lowering kit. The kit I chose was the eibach pro-kit. It will lower the front 1.5" and the back 1.3". You can see the car at

The problem is that I have heard that I need to get adjustable rear control arms due to excessive camber in the rear wheels. I would just simply find out the hard way and install the springs and front camber kit if I still had my old rims, but when I got my 18's I got rid of the OEM rims and the sidewalls on the 18's are too rigid and will show excessive wear extremely fast. If anyone can help me out with this, that would be awesome. I just need to know if I need to install adjustable rear control arms when putting this kit on my car. Feedback will be greatly appreciated. Thanks,

I am just trying to get this post to the top so MAYBE someone might read it.

 

I read it the first time around, but I have no personal experience with them so I remained silent. but I did a quick search on 3si for "lowering" and found this thread. "Lowering"

Both of those sites are dedicated to the Stealth/3KGT platform. They may be able to steer you in the right direction.
