are you seriously racing your car at the track? or you just want your car to be faster when a ricer revs at you?
decreasing the moment of inertia will make your car a little bit faster (both having lighter wheels overall and with smaller wheels the mass isn't as far away from the center).
exactly how much would depend on the specific wheel, its size and weight. also the tire weight is a factor and the amount of pressure needed in the tire, etc.
just be aware that some REALLY light weight wheels are also less strong because of it. i'm sure you can read lots of stories of people breaking their rota sub zeros. using a really light weight wheel for daily driving would be a bad idea.
if you really care about your track times, pick up a light pair for the track, but leave them off for daily driving.
