I’ve been converting my Slash 4x4 into a basher truck for the local outdoor track at the park.  One thing I noticed was that the truck was making a clicking noise at full right, which I thought was the body hitting the tires.  I narrowed down the noise to the wheels.
These are Pro-line Calibers pre-mounted on Renegade wheels.  The inner ribs stick out too far and hit the steering blocks, so you have to trim them down with some curved body scissors.
Original wheel on the left, cut down ribs on the right.
Problem solved!
