I have wear there on my 137". I'm going to buy extra wheels for that area and the front bend on the rails as well along with DuPont slides. The slides wearing on the front bend is just wear but farther back on the skid causes the track to get in a wave motion really slowing the sled down. In talking with some big speed guys they say this chassis responded very well to extra wheels!
