The Traxxas hexes a few of were running did in fact narrow the rear of the car. It was a temporary fix until some purpose-made hexes were available. That said, I picked up a set of TRA3654 wide hexes (8.2mm according to my calipers) to try this weekend.

The 3654's (Slash fronts) are the ones you want for the rear. The Slash rears are too narrow.

Anyone know the size of the shim to do the ring gear.
