In some states a stubby bumper is illegal. Although, the law is seldom enforced. Stubby bumpers look better with flat fenders, but look kind of dumb with stock fenders if you ask me. Mid-width bumpers look better with stock fenders. Full width bumpers (other than stock) can weigh a ton, unless they are made of aluminum.
