Rear Wheel Toe In

does anyone think that using a couple of washers between the carrier and the trailing arm front bolts to shim out the bearing carrier is a bad thing or should I have a custom shim made to get it toed out,,

passenger side is toed in ever so slightly and wearing that tire more than the others,,

stuck a thin ( .054 ) washer in there and bolted it up, settled it in, and its real close, may need to go a little thicker
