Yea, I was going back and forth between these and the Ultraleggersa's just for the weight. I opted for for the Forumla4's just because I don't really track my car and the few extra lbs. vs look I prefer weighed itself out (pun intended? lol). The Formula4's are still a three and a half lb. weight reduction on each wheel vs the stock Rado's. Are you referring to the Kosei wheel's I had on before with regard to the weight? I didn't weigh them myself, but they are sitting in the garage so when I have a chance and find a scale I could weigh them no problem. I need to clean them up and take pics for when I sell them anyway.
