good question.

I haven't heard of any changes to to the suspension that would get you to what the +3mm wheels give with zero offset wheels.

I am thinking its basically the same type of wheel you get as far as offset goes (or close) that it comes with out of the box as the sc10 4x4 wheels out of the box are zero offset, or at least, AE zero offset. Losi's zero offset may be slightly less offset, if that makes sense.
