Wheelbase

[butters86]

I've seen on setup sheets it looks like it's possible to widen the wheel base on the Team C tc02. But I can't see that I can do this on the Mad Rat itself?

I've fitted a 1mm metal washer between each wheel and hub which has widened the wheelbase by a couple of mm front and rear. It seems to have improved the handling quite a bit. (more than I was expecting actually)

Are there any downsides to doing it this way instead of buying the proper hex shaped spacers that you fit into the hex recess in the wheel?
