Here is a Steering Stop Kit which includes one driver and one passenger side steering stop, mounting hardware and instructions. It is designed for Club Car Gas & Electric 1982-up DS golf cart models. This kit will prevent you from performing a maximum turn, which can sometimes eliminate tires rubbing.
Note: There are several factors that can cause rubbing, so this isn't a guaranteed solution.
