Thank You for the insight. I do plan on putting on wider tires which has more frontal area but it is only by 10mm (stock tire is 235, I plan on 245). I hear your concern about the aerodynamics of the wheel design but I highly doubt that Honda designed the factory wheel to be aerodynamic because it certainly does not look like any of the aero wheels that hybrids and electric cars typically come with.
I read that rolling unsprung weight is 4 times the amount of sprung weight. It seems like it would make a big difference, but then again I'm a newb at this stuff. I will read more though. Thanks!
