Thanks for the response. If I need to, I'll take your suggestions, and run the spacers.
Just for your information I came up with another solution. Instead of spacing the wheel out, why not move the brake caliper in.
Turns out that many cars run the 5 X4.5" bolt pattern. The Ford Ranger pick up has this pattern, and the rotors are offset 3/4" back from my current application. Now if I run 3/4" spacers behind the brake brackets, I have accomplished the same thing without affecting scrub radius. Hope it works. Thanks again.
