I wish just "thinking light" would make my car faster. What about "lightweight racing lug nuts". Now I know it sounds kinda silly for a street car, but if people spend hundreds on light rims, why not go the extra mile for the lugs too? Would it really make that much of a difference that someone would want to spend $75 on them? The OEM ones are strangely heavy for how small they are, but I don't think racing ones would really help.
