ok , so i ordered spacers for my wheels, and they finally arrived yesterday

i currently have the OEM 19 rays, and as i was bolting on the lugs, i noticed that the screws that hold it together arent long enough!! so im guessing i have to buy new bolts, but i think its going to be a bit** since i have to take off my disk brakes, anyone have any suggestions? where can i buy them? I am in desperate need of wheel spacers so i gotta get this done, they are 15mm,(1/2) inch, here are a couple of pics of the spacer, and how my car looks and how i want it too look.
