No, the closer the overdrive is to "1", the shorter the gear. Again, this is a trivial detail, particularly because it's just 5th gear. Personally, I kind of prefer a taller 5th gear....er, despite having a daily driver with a 4.88 R&P and 0.825 5th gear!

Anyway, we all know Mazda broke every rule of thumb we've ever devised! Factory sunroofs on GTU-Ss, dealers installed whatevery they saw fit, and plenty of TIIs have steel hoods. Anything with a rule has an exeption. The only one thing I am absolutely certain about is the car I actually owned for 4 years. YMMV.

Not that anyone will care, but here is a picture of my old GTU-S. Of all my RX-7s, it was my favorite and selling it a couple years back was one the worst mistakes of my automotive life.



I sold it to finance the RX-7.5; my 1st gen with a Peripheral Port 13B, Weber 51IDA, 4.88 R&P, braced axle, etc. etc, the tire/tool trailer and an 8,000 mile round trip journey to Florida for one race. Also a cool car, but lacking the social graces of the unflappable, mild-mannered GTU-S.
