Just received a slash 4x4 roller in the mail today and when putting it all together I realized that the 2.2" wheels I was using on my 2wd slash don't clear the caster blocks up front when I turn. The inside of the wheel hits the block and wont turn. Anyone found a way around this or do I basically have to use the stock style wheels, 2.2" outside 3" inside or something like that?
