I know you're not looking to put more money into it right now, but I noticed the manual is only rated 12/14/16 while the auto is 14/15/18. I would suggest looking into the differences in gearing of the trans and differentials, if it's not already geared too low, with the aerocap and smooth underbody, it could probably make use of higher gearing. If it's geared too low already, you might see smaller than expected gains from the aerodynamic improvements. Hopefully there is a fifth gear swap available.
