Bigger the final drive, higher rpm would be needed to reach certain speeds.

1:56 "SO much more power!"?! NO! You have exactly NO more power! If you want a good illustration of exactly what going from a 4.1 diff to a 4.3 diff will do for you, here's what it did for the '17 BRZ vs. previous 4.1: https://drive.google.com/file/d/0B78...YU3YzZ0JB/view https://drive.google.com/file/d/0B78...uaXRfRl9j/view 0-30mph: '13 = 2.3s, '17 = 2.2s 30-40mph: '13 = 1.0s, '17 = 1.0s 40-50mph: '13 = 1.4s, '17 = 1.4s 50-60mph: '13 = 1.6s, '17 = 1.6s 60-70mph: '13 = 1.9s, '17 = 1.9s 70-80mph: '13 = 2.2s, '17 = 2.3s 80-90mph: '13 = 2.8s, '17 = 2.7s 90-100mph: '13 = 3.2s, '17 = 3.2s 30-100mph: '13 = 14.1s, '17 = 14.1s |

In addition, you get higher wheel torques, which can be very good with a fast revving naturally aspirated engine. The difference between 4.1 and 4.3 is almost irrelevant, but I will switch from 3.9 to 4.67... it will feel like a completely different car. Especially with the very long steps between gears in the automatic transmission. |

Automatic speeds with different FD.
As you can see, the automatic transmission has a much too high gear ratio and the gradation of the gears is very bad. I wouldn't change anything with manual transmission, but definitely with automatic transmission: |

True, but I was looking for an actual value in rpm at those speeds.
