I saw that in one of the posts above and thought it was worth repeating. We also ran one side of the front higher than the other if the track had a lot more right hand turns than left. The higher pressure on the side that had the most use.
Actually the reverse is true, more air pressure in the rear reduces understeer. The best way is to chalk the tire and do a couple of runs.
