if you wanna spend the money go ahead, but the math says they dont really matter, i know i am a mechanical engineering student. the effect that they make is about the same as a pebble, or a 2 in square piece of gravel is gonna effect your run. you wont even notice.
but congrats on your winning, but I am SURE that it is you superior skill that makes you win and not some lug nuts. but, if i could find some nice looking, locking, light weight lugs, i would buy some too.
later
