Underdrive pullies, aluminum driveshaft, lightweight wheels, and surprisingly enough, I got better mileage when I added a cold air intake and tuning.

 

Wheel and tires? anybody had any luck from that?

 

with reducing unsprung weight and freeing up wheel horsepower Im not convinced it will make a noticable difference on gas mileage. I saw no difference at all in MPG with UDPs and aluminum driveshaft on my 2007 GT. with my '07 i went from 3.31 gears to 4.10s and I gained about 3mpg in town, but lost an equal amount of highway. so i went to averaging around 17mpg.. i get better mileage in my 2012, but switching from the 3.15s to 4.10s I gained about 1mpg in town and lost 4mpg on the highway, so not as even.

The cost of doing the any of the mods mentioned wont be outweighed by the savings in gas. best bet is read on how to drive to save gas. slow acceleration, coast to a stop, every time you touch your brakes you are wasting gas... drafting (dangerous, wouldn't do as you have to be right up behind them to get it to work right) depending on how you drive now you can easily get 3-8mpg out of changing your driving style.

read a bit on hypermling.

 

I personally like to see just how bad I can make my gas milage..

 

Hehehehe, so do I.

Al Gore must hate me.

 

you don't mod for mpg and reap the benefits. check your tire pressures. shift early and shift often. don't brake. travel at 55mph. you have tons of options for driving habits to help increase mpg but that's about it.

if 4$/gallon gas is a concern or even a surprise to you, you're in the wrong car. it's going to get higher, too.

 

Hell yes. I've been trying to find a decal that says "Powered by fossil fuel". That oughta make a lot of environmentally folks pretty happy.

 

The left foot delete is good for about 4 MPG . Drive with your right foot only or get scooter, mods for MPG are worthless. Spend 200 for a extra MPG, where I the break even point?

I want one that says "Burning liberals' hopes and dreams as fast as mechanically possible."
