My best estimate, after using the online tool in the sticky thread here plus some best guessing, if I can get my Cd from 0.33 to 0.30, it'll save $0.90 per 100 miles@70mph, or $90 per 10k miles, I'd break even on $120 in just under a year, assuming those underbody improvements can change the Cd that much (realistically I don't know if they will or not).
