That is basically true but remember also when it involves rotating weight vs static weight. My understanding that weight that moves (rotates) is effectively 3 (maybe 4) times the weight as if it was static. Also what tire is ran on the wheel makes a diff. A Metic tire like what I have is MUCH heavier then a Moroso DS-2 but the DS-2 is track only and the car's weight needs to be signifigantly reduced.

Simply taking weight off the front of the car, reducing rolling resistance is going to make a difference. I gotta toss back on my 17 x 9's at some point but man, I really liked daily driving my 15 x 4's Convo Pros.

Skinnies will usually allow a couple more MPH on your timeslip.
