Shocks generally have eyelets at the top and bottom where they connect to the suspension. Struts have an eyelet of some sort at the bottom, but have a threaded rot that sticks straight out of the canister section.
Left is a shock, right is a strut.
I enjoy having coil-overs because I like to be able to raise my car up when my family comes to town or something where I need to carry a lot of people, but I can still be low when I want.
You could just get some lowering springs like Eiback, H&R, Neuspeed to have a perminant drop.
You will also want to replace the struts because the stock ones won't stand up to being lowered all that long.
