since the lugs are so close to the center of the wheel, they really arent going to make that much of a difference in rotating weight. being so close to the center of rotation they create such a small moment that it is probably negligible as compared to if you were save 10 grams at the edge of the wheel. and saving 40 grams in unsprung weight is also negligible when compared to a 200 pound suspension set up. my two cents
