Thanks!
The rims in front were hitting the hub of the rotor. Spacing them out prevented that.
Rim width, I believe, is 8'', and I have absolutely no idea what the offset is...
And nope, I'm running the bone stock rear axle that came with the car, which I'm pretty sure is a 7 & 1/4''. (It might be an 8 & 1/4'' though, I don't remember)
