Im not sure which trans your V6 has but I know the G-series mazda trans has several 5th gears available. I swapped a .71 5th from a Mazda 626 in place of my .8 5th in my Mercury Capri trans (G25MR). It dropped the rpms at 60 about 300-400. Cruises 60 at about 2500 now.

Larger diameter tires will change your final drive ratio. the only problem is that it changes them all, so slower acceleration could be a downside.
