Rep Power: 0 How bad does Rims mess up gas mileage?
I know people always say that buying 17's, 18's, or even 19's can mess up the gas mileage but how much does it really mess it up?, how many miles per gallon do u lose by adding rims and lowering the car?

Rep Power: 356 Depends on how much stop and go driving you do. If you go with a larger/heavier wheel the more power that is needed/wasted getting that additional weight to accelerate, so more Gas is used. For freeway driving, there wouldnt be that much of a difference.

Rep Power: 0 I dont believe lowering the suspension would cause any parasitic loss in fuel economy and may perhaps improve it. The less ground clearance you have reduces the aerodynamic lift from under your car. However a larger diameter wheel will decrease your fuel economy because of the greater force needed to turn the wheel. If indeed you are looking for something like 18's or 19's, I suggest you get lightweight wheels if you are concerned about milage per gallon of gas.
Remember, no three of the following apply to any wheel, but only two:
Lightweight, Strong, Cheap
You can have a strong lightweight wheel but its gonna cost you an arm and a leg (forged wheels). You can have a cheap lightweight wheel but it probably wont be good for track use/hard driving/long-term reliability. You can have a cheap strong wheel (cast) but you sacrifice accleration and fuel economy.
Hope this helps, happy buying!

Rep Power: 322 Lowering ur car does affect gas mileage cuz of alignment. Once u lower ur car u cant go back to stock specs. So no matter what ur car is gonna have a bit toe in toe out which causes resistance makin the enigine push harder than stock height.
