I'm running in an awana grand Prix this year and this is the first year we can modify the width of the wheels. Should I make them narrow or leave them alone?
If you make homemade razors and leave the hubs intact (not a terrible idea), you're going to want to inset the DFW wheel so that the distance between the inner edge of the wheel and the rail is the same as it would be with a fat wheel. If your alignment is good, I imagine you could go without insetting the rears.
