The 8 has always come with auto. The early models were 4spd, my 07 is 6spd.
I really like to shift gears, but I don't like all the associated troubles like throw out bearing noise, and 2nd gear synchro grinding.
This 6spd auto is really good on the track because I can concentrate on driving while the car does the shifting.
I don't even use the manual shift, I just leave in gear, it shifts @7krpm, and if I jump off the gas before 7k it stays in gear to be ready for the throttle in the corner.

My 2nd gear synchro stopped grinding when I put better oil in the gearbox. Chances are, there's still some rubbing and grinding going on even in your automatic, you just can't tell because you don't have a metal rod connecting your hand directly to the transmission. A gearbox is a noisy place to live.
My car also runs 4000rpm @ 78mph in 6th gear. Don't bother me none -- rotaries run 50% higher rpms than piston engines anyway. So to do the math, it's the equivalent of running 2667rpm @ 78mph in a piston engine. That's quite reasonable.

I think you should reconsider this statement, and your math is wrong.

thank god for stability control...
i prefer to balance the car and keep in the same gear as god intended lol

So right after I yank the wheel, (all at once is the proper way anyway, not slowly turn) I jump the gas. As I'm settling in on the drift after slowing from say 90mph to 60mph, the tranny is shifting down hunting the right gear, and I feel the (low torque remember) power smoothly come in. I did say that the tranny stays in gear when I jump off the gas on a slow speed corner (say 40mph).
The auto doesn't sound like a pure race car, but its my dream car, and the newer supercars are gonna shift similiarly.

Even with 6spd Automatic.
I also got the highway EPA mileage of 25mpg when I drove it to Dallas recently at 70-80mph with AC on.

S2 has a taller 6th gear so top gear speed/rpm is the same as S1 only 1st-5th gear are geared down.

I changed my rear ratio from the standard 4.4-1 to 3.9-1 and that dropped the revs down by around 500rpm. So now at cruise speed which is around 130kph or about 80mph, my car sits at around 3500rpm. My car is a JDM 6speed.
The gear ratio set that I used was from a fd RX7.
I also hated the high revs the RX8 revved at on the open road. I was used to my RX2 which had a 5speed and 3.9 gears and sat at around 3-3500rpm at around the same speed.
