What kind of driving are you doing? If you're doing this for track driving, then it's probably a good idea. If for the street or canyon carving, the difference would be less perceivable. And most race tracks aren't full of potholes while streets are. You don't mention where you're from but it sounds like most roads in the US are rough. Unless you're going with carbon fiber wheels, chances are lighter weight means less strength, which means they'll bend easier. Something to consider.

If you're buying to change up the look or you love the style, I say go for it. If you're buying them strictly for the performance adv for the street, there are better avenues to spend your $$$ on.
