The hood is aluminum, but CF is still a bit lighter, just not as much of a benefit as on a car with a steel hood. The trunk is steel so CF there would save some weight.

Lighter wheels and tires is the single best place to save weight since it is UNSPRUNG and more importantly ROTATING mass. I've heard of a few people losing the spare and tools and replacing with a can of fix-a-flat and 12V air compressor.

Lighter battery is good for a few pounds.

Taking the top off completely is good for at least 50lb.

Keep tank no more than 1/4 full all the time. (Gas is actually quite heavy ~800g/L so figure 3.2kg/gal).

Obviously, every one of these is a tradeoff for convenience or function. Even a lighter weight battery is a tradeoff since it won't dump as many amps and could be a problem starting the car if it is very cold.
