I need help with american racing/modern wheels!

[ihatericeburners]

I would like to go with these:



But i need some help with some questions. THey are 18x8.5, 19 offset, 5.50 backspacing, 6X5.5, with the smaller hub dia. So now the questions...
1. I would need spacers correct?
2. And that would adapt the smaller hub onto the larger on without a problem?
3. i wouldnt loose any steering?
4. my ECE brake conversion will clear this?
5. My drop spindles and stock springs wouldnt cause any rubbing?

I may have forgottn a few more ?'s with all the frantic typing, but i really have my heart set on these now. THanks a bunch for any help!
