Final Drive Calculator?

Anyone know how to calculate what my rpm will be at 100kph
With an AT and 4.56FD? At 4th, 5th and 6th?

Wondering if its a good upgrade for a car that is city driven with only 100kph max highway speeds.

Autox over track.

This calculator right here is hands down the best I’ve ever seen. The URL is crazy long with all the specs from the gearbox embedded in it so the site generates short URLs with goo.gl. This short URL will preload the specs for the pre-2017 6MT.
