In the rear you can go with DIY or custom made adjustable camber arms or there is a k-Mac kit for the rear as well. Also do your homework on trimming the bump stop and spring pad sizes. There are several alignment and lowering threads to brows through. If you install and do nothing you will most likely have to replace tires quickly.
This is what -2 will do to your tires up front. Had these on for about a year after eibach install. Camber bolts only got me to -2 on the driver side.


This is mine on eibachs and konis. I have increased spring pad sizes since the pics so it sits a little higher now. Also running bigger tires up front. basically Snug 2 finger gap in the back and one finger up front.
