The stock wheels/tires actually worked pretty well on the blue groove track I run on. But it was bugging me that I couldn't use the Slash proline wheels/tires (I have several new sets). So I was sitting there and I remembered that on my CRT.5 I ran Associated truck wheels by removing the 12mm hex and just using the pin. "Light Blub" well I have some old Proline Bead Loc's off my SC10 sitting right there so I pulled off the hexes and the installed the SC10 wheels. They actually fit pretty good, and cleared the body (at least in the track). I am not sure how they will clear in the up/down range when the suspension bottoms out since they are bigger in diameter. The larger size may also require regearing and will effect the handling (higher CG, more mass, etc.) but I will try to get out on the track this weekend and run some tests.

Parts, need to add a few spacers, otherwise when you tighten the wheel it will bind on the carrier.
