Hi. I plan on getting a HX Coupe some time in the far future but like to do my research early.

I'm just wondering if lowering a car can improve fuel efficiency. I want to either get '04 EX alloys or the '01-03 EX alloys or '99-00 Si alloys. I know tire size and correct pressure and other stuff factors in, but suspension wise, Can it help gas mileage or will it hurt?

I want the HX Coupe for the gas mileage but also love the look of a lowered 7th gen with those above mentioned alloy wheels.

Thanks.

never heard of suspension helping out gas mileage!?!?!?!?!!?!?!?

damn dude, youre going overboard with this fuel efficiency crap. The hx gets like 44 mpg, you don't think that's enough??

actually it does, the lower your car the less air that travels under the car which can slow you down by creating diffrent currents under it...

you become more arrow dynamic when lower

So does that mean that midgets are more aeroynamic than normal people????















Sorry I couldn't resist

umm, in theory

haha, i guess i am taking it to extremes but i was just wondering.

those 99-00 si alloys or 01-03 EX alloys are not heavy right?

not as heavy as 02 si's i think you save about 4 pounds with the old ones, i like the older ones better

will lowering actually make a difference to gas mileage?
even if it does, i bet its like barely noticeable either if its in a bad or good way.

I might make a small difference but not much to tell, maybe a few extra miles. In theory it should make your more aerodynamic like hondaluver said.

The front of the car still has the same surface area. You're knocking off about an inch or 2 of vertical tire area so say, 12-30 sq inches taken out of the frontal area which is many square feet. The air drag may go down an itty bit. Not enough to make a significant difference
Then you're putting heavier wheels on with fatter tires.
And you're taking this a little too far. If you're lowering it, just do it, **** the gas milage.
