Maxing Mpg

Can anyone walk me through maximizing the mpg's in my 2010 LT 2dr? I'm no mechanic, but I know a thing or two about cars and a lot about tools. I'm new to mods but I'm willing to learn. Whatever wisdom you guys have would be great, but I really want to get the most out of this great car.

Some ideas I had:
Remove back seats
Remove spare tire
Replace regular tires with more economic ones
Rebalance front seats with carbon fiber racing seats.

Here's what I've done to it already:
Ken wood 12" subwoofer with ken wood 1000 watt amplifier.
Oznium inferno underglow kit

Also Alpine speakers in the front and back.

Wouldn't the stereo components just take you a step backwards in weight reduction?

You're going to sink a crap ton of money into carbon fiber seats?

You're correct, but I also like to look good. I'm wanting a balance for now, but I will eventually take that out.

Yes, yes I am. Nothing is too expensive for my baby if she wants/needs it.

Removing seats and spare will have no effect on fuel mpg. Tire inflation on the other hand will affect to a certain degree. Driving habits have the most effect.

Like I said, those were ideas. If you have better ideas, I'm all ears.

Won't a reduction in weight have an effect if even just a little? Especially in acceleration. The engine is having to do less work and therefore consuming less fuel. Am I right?

Re: Maxing Mpg

Pulse and glide on the road.

Set in neatral at long lights.

Set in neatral going down hills.

Turn off the daytime lights when cars are not around you.

Warm your car for 20 seconds in the cold mornings.

I average 32 mpg winter, and 36 in the summer, city and highway combined.

Thanks for the driving advice! Any ideas on modifying the car itself to increase mpg to do even better?

Honestly the money you spend on parts is going to far outway the gains in MPG. I have about every bolt on that can be put to this vehicle and hell ya I get great millage for how I drive. But it just isn't saving as much as adjusting my driving habbits.
