the miata box and the rx7 box STILL have the same 1st to 2nd shift lump with about a 3800 rpm drop. but the 2 - 3 - 4 is much better....
i think the best overall though is the Richmond Gear Super Street
The drops are never below 6100 rpms and the 5th gear would still leave a 3800 rpm engine speed while cruising at 70 mph...
if i want to not worry about the freeway ever, then i think i would opt for the Richmond Gear 4+1 but the 5th gear 1.1 ratio and a 70 mph engine speed of almost 5500 rpms is a turn off to that.
The T10 box might be slighly better, but there is no overdrive gear and the difference isnt that big between the Super Street and itself.... Ill have to check its other ratio combinations to see if anything can be gained
