Don't use the Eibach Pro kit with OEM struts. OEM struts are not meant for these types of set-ups. Use H&R's smallest drop kit if you're looking to save money or keep the stock struts. H&R makes a spring kit with a very minor drop (1/4").

Cambers adjustment kits may or may not be needed. It just depends on how radical the drop ultimately is and how your overall suspension is set up. Either way, you'll most likely need and should have an alignment done after doing your suspesnion work.
