Dang! I was going with this idea also! CRAP!
I was going to use the New Era ones

But I won now because im sure the problem will be the same as yours. Guess I have to go back to 30's series rims/tires now. Sigh...
I wonder if I can just use the 8mm axle hubs a truggy uses. And then have Mike, or someone make me something like his bore reducer to fit in there. I cant see any problems with that, other then getting them made. And then use something like the RC8T hubs for the offset, then we can run 0 offset, and have perfect width. Maybe Mugen, since I know my buddy has some I could have, and get this figured out
Time to get the ideas flowing!
