I would try to give you a recommendation but I am not familiar with Mazda's. There may be some more gearing options available through Mazda overseas. I know lower Mitsubishi gears can be had overseas through the dealer. THey are a little pricey, but they are well worth it. I tried running 4.11 gears with 31" tires and I burned up a brand new clutch in 500 miles because I thought I could get away with running higher gearing with oversized tires.
