Those are two very good points DVG. Thanks for the help.
Hahaha this reminds me of a friend from high school who wired in Christmas lights inside his '92 Chevy conversion van and never took them off. I think he still rides with them to this day.

The tendency of rotating mass is to keep on rotating. Without forces like friction and wind resistance acting on it, it would roll forever. Just as the tendency of a body in motion is to remain in motion.

I agree with you that a larger inertia will reduce fuel economy. It does take a bit more energy to get it moving, and then that energy is wasted when you hit your brakes. But once at speed, it shouldnt make much difference at any. So it would be different for someone with mostly highway driving vs. city
Additionally, I dont think that it makes enough of a difference to affect wheel diameter selection. Maybe if you are a hyper miler. Going for a lower tire width or lower rolling resistance would be much more effective methinks.

What kind of lip? Maybe if it only goes under the bumper, and not around the sides of it. Show pic.

PM one of the body kit vendors, they should be able to tell you for sure.

That means it will kill the mpg of the car the larger wheels are going on. MPG while rolling is always going to be high since it takes very little power to keep something moving at a constant speed and less power to accelerate something that is already moving than it does to start moving something that is standing still.

Yes but as long as tire diameter remains constant, those wont really change based on the wheel diameter.

Accelerating from a stop is what kills your average MPG, that is why you will always get more MPG if you drive freeways more. Accelerating from a roll or maintaining a constant speed doesn't matter as much. Adding heavier wheels means you need to put down more power to get your car moving, which really kills MPG.
I understand why highway mpg is better than city mpg lol, I already said that. Everything is rolling, the car has momentum, all thats required is to keep it rolling.
Anyways I fully agree that it will affect city mpg, not very much though.
Shouldnt affect highway mpg

I'd be surprised if they were the same since the coupe is wider than the sedan by 2.5 inches.

Wow finally a response, I'm surprised you even found my comment since it's so far back haha. Anyway good to know, so that means I can put HID's in there and have them at full power when I apply the highbeams as long as I have my fogs on at all times? (Don't worry I'll be modifying the shield to prevent glare when the fogs are on).
1. " Anyway good to know, so that means I can put HID's in there" - in where?
2. "and have them at full power " - What do you mean? Nobody runs HIDs at half power
3. "when I apply the highbeams as long as I have my fogs on at all times" - a. design dictates that fogs automatically turn off when high beams are turned on (fogs hurt distance vision)
- b. Why would you have your fogs on at all times.
4. "(Don't worry I'll be modifying the shield to prevent glare when the fogs are on)." - Im not sure which shield you are referring to, we have reflectors not projectors.
