Yes, similar chassis. What it is hitting? This was also a problem with the Redcat Crawler I have with the Tie bar contacting the Differential case. Redcat came out with a revised bar and knuckles (which came with the truck) to correct this and add more steering angle. Now it’s limited by the tires contacting the shock springs which required some steering limit in Ardurover. It has a turning radius (TURNING_RADIUS parameter) of 1.2m which isn’t great but for a crawler I suppose it’s typical. Lockers have a lot of tire scrub while turning which doesn’t help. My other truck turned very tight but it was a 4WD Basher and not the greatest vehicle for a Rover.
So you would have to find something similar either from the manufacturer or aftermarket. I’m not familiar with that truck but some of these are built by the same manufacturer and re-branded so maybe it’s possible. I found that to be true with my previous Rover which was a HobbyKing truck.
