We have the same problem with our. 80-90mph seems to be its peek time then you start going over, and over, 120...130....135... and it seems like it takes forever. You watch videos of STIs speedos and they are like 120, 130, 140, 150 and its like Why cant my car do that!
100 on the highway? no, not safe unless nobody is around. Place of choice, backroads out in the middle of South Dakota

anyone else feel this way?

for the 2WD version.
So it's geared to get to 100 quickly and then tail off.
Probably better that way since above 100 isn't needed that much.

A car needs *a lot* of power to pull hard in higher gears (as you describe, 100MPH+) so it can overcome increasing wind resistance (roughly velocity^3). Gearing helps, you'll see in the table below that the 6MT has a big gearing advantage compared to the 5AT. The "at axle" gear ratio is more telling since it accounts for the gearing in the differential. Also, note that the G35x has higher numerical gearing (better for acceleration) than a 2WD G35 5AT, so ignoring weight differences, it should pull harder than a 2WD auto sedan. Other cars like the M3 and the Evo have even higher numerical gearing.
The M3 (e46, 2000+) pulls hard at higher speeds even though it has amazingly low (high numerical) gearing in the first two gears and drops off after that. Comparing the M3 to the Evo, once in 3rd and 4th gear the Evo has a greater numerical gear advantage. Taking into account wheel diameters M325.9", Evo 25.3", then the M3 is at a bigger disadvantage numerically. From my experience at Pocono Raceway, my lighter Evo actually pulls away from the M3 at higher speeds despite the difference in rated power, possibly due to the gearing.
The c6 (corvette '05+) has lower numerical (worse) gearing than all of the other cars. Yet, it pulls very hard at 100+ MPH due in part to gobs of torque across the rev-range.
