I wound up using these in chrome. With proline gladitors. They worked great.

I did go with the traxxas front rustler hexes. Had to swap out the pins with traxxas pins cause the ofna ones where to long.
The only problem i had was the axle on the traxxas car is a bit thicker than the stock crt.5 axle. so there is some play in there.
And after putting the front wheels which have a deeper offset and the hexes i only get about 1 1/2 to 2 turns on the wheel nuts so i might go back to the ofna hexes to see where it lands me. As i dont like not having threads into the nylon part of the wheel nut.
