Absolutely worth it. Reducing unsprung weight is one of the single most effective ways to better performance in all areas. The only thing better is reducing rotating unsprung weight, which is what you would be doing. Five pounds per wheel, when stated as a percentage of wheel weight, is significant. You are actually getting a "two for one" deal when lightening wheels, because you are also reducing rotating weight. That has as much of an affect as reducing unsprung weight. In other words, losing five pounds per wheel will be an even more dramatic improvement than five pounds off of, say, a lower control arm. You are geeting the maximum benefit possible by taking the weight out of the wheels.
