Are those the same rims I'm using? my pictures are in post 10, 12,15? I got lucky with the rear ones as I'm running an E body axel that sticks out the couple inches on each side more than normal. On the front I used adapters at first. I got tired of taking the adapters off when I wanted to put my drag tires on so I finally hoged out the center of the front rims so they just fit on over the stock disk Brakes. I noticed it would be possible to have a set of rotors turn down around the centerpiece so they could fit inside the rim but then the rims would only fit those rotors. Like I probably may have said in my other post - I'm not a huge fan of 18's, but for the price it was hard to turn down, and now they're growing on me.
