I wouldn't mind spending a little extra time and money for better results. Car currently just got 57 mpg going from Houston to San Marcos averaging 60 mph. Cars current mods are lowering springs (two inch drop), put mesh behind the grill to help protect from rocks and decrease some air going into the engine bay. So if I was to only see a 5% increase from a underbelly that would actually be very nice.
