carbon fiber body parts are just for looks. they aren't as heavy as the part they replace,( i replaced the hood AND trunk of my hatchback celica) but it does nothing to gain mileage. in fact the effect is less noticeable than riding with an extra passenger! my hood was 25 lbs lighter and the trunk was 30 lbs lighter.





you could start throwing things overboard to lighten your load, but why?? its not worth it in my opinion.
