is it actually possible to improve the aerodynamic of your car by yourself and significantly lower the MPGs or would anything you can do either do nothing or even make it worse?

Some old cars could benefit from air dams.
Definitely possible but looks ridiculous. Just taping up the grill and putting Moon discs on is pretty good but obviously can lead to cooling problems for the engine and brakes.

take off factory spoilers on non race cars

lower it a bit

When it comes to this, I have a question for a real armchair engineer:
If you just improve the aero significantly, would you get better highway MPG's with the same gearbox or should you change the gearing for full effect? Seems like you would need taller gears to really notice the difference. At least a high O/D gear.

Depends at what RPM your engine reaches peak volumetric efficiency and how fast you drive most of the time
Yes. Google hypermiling and ecomodders. Though it'll inevitably make your car look like a hackjob and make you look like a faggot.

go to ecommodder.com
The answers are yes, yes and yes, but regardless of what you do it's likely to look ugly
>>14123203
Look at that smug faggot.

Lowering does not improve mpg instead it decreases it.
>>14123190
You will get better highway mpg's even if you don't change the gearing, but it won't be much. You will have better passing power at speed though.

Pizza dish wheel covers, lowering, and undercarriage aerodynamic mods are usually the best without fucking up the looks too much.

I guess that's why salt lake racers have so much ground clearance?
>>14123261
That's so the car doesn't catch air and flip at speed.

spoilers reduce drag dipshit
buy a Citroen DS or a Tatra.
this is actually kind of cool. he gets 80 US mpg compared to the 49-60 US mpg quoted
>>14123190
Too may variables to have an objective answer. Reducing drag will always give you better mileage though, since the engine will need to output less power for a given speed, regardless of gearing.

spoilers reduce lift but increase drag

>>14123296
Not that anon, but spoilers reduce drag. He's right.
Wings increase drag and downforce though.
>>14123261
Such a sexy Hawk
>>14123663
That's semantics. And even if we say that a spoiler is different than a wing, I can guarantee that 99% of spoilers on road vehicles are purely cosmetic and do nothing but increase the drag of the vehicle.
