I tried fit the rims on the CVDs i have, and they appear a tad small. I think a simple pass of the 3/16 drillbit should take care of it.
Had to do the same thing for the ones I used. I Put a 1/4 inch bit into the back of the wheel just to 'countersink' the axle hole so it would fit. Other than that they work great. Personally I really like their blue and green colors. They are just different enuf to catch the eye but arent' the so common 'neon' look that is kinda overdone IMHO. These rims seem to hold up extremely well too. In my duratrax nitro evader bx with an OS 18 they really take the abuse
