I had all 4 standard types of braces on my Civic, but not necessarily for anything MPG related
Front upper/lower, rear upper/lower normal bars... at some point, I had an interior C-Pillar bar, and a floor stiffener bar as well.... the added weight was only justified by the nearly 20MPH cornering increase before traction was an issue.
Good job on the DIY!

I'd like to think that people might open their eyes at some point... instead, I find it more and more likely that I'll just close mine.
