It depends: how much work is each 1% improvement in cruising fuel economy worth to you?

I'm not familiar with the Civic drivetrain lineup -- is there an apples:apples comparison between 2 models that shows the MPG benefit of this final drive?

I made quite a large change to my final drive -- went from 4.39 to 3.52. It made about a 5% improvement in fuel economy in my Metro/Firefly: Project 'nerd gear': taller tranny transplant nets +5.2% MPG - MetroMPG.com
