I put 8 inch wheels with 4 inch back spacing on the Demon Adam. I also put 255-60-15's on. With the back spacing, the tires are just inside the lip and lots of room over to the springs.
The Demon has a more open wheel well and tons more room then the Dart/Scamp does. I'll need to offset my springs and run 5" of backspacing to get that much tire in it.
