Mainly 3rd and up I would guess -
80k/50 mph - 3, 4, 5, and 6th
100/62 mph - 3, 4,5, and 6th
120/70
140/90
160/100
If you could show us those, that would be really great.
Thanks

You can use the values below to calculate RPM at a given speed (or vice versa) for the MT 4.10 ratio:
1st: 0.007587214
2nd: 0.012986979
3rd: 0.019447632
4th: 0.025810531
5th: 0.030766153
6th: 0.035282286
To calculate RPM at given speed, divide speed (
must be in kph) by appropriate multiplier above for the gear you are looking at.
E.g. 50kph in 3rd gear = 50/0.019447632 = 2571 RPM
E.g. 100kph in 4th gear = 100/0.025810531 = 3874 RPM
To calculate speed (in kph) at given RPM, mulltiple RPM by appropriate multiplier above for the gear you are looking at.
E.g. 4000RPM in 3rd gear = 4000 * 0.019447632 = 77.8 kph
E.g. 4000RPM in 5rd gear = 4000 * 0.030766153 = 123.1 kph
Note the above multipliers are based upon car with factory 18in wheels (265/40) running 4.10 FD ratio.
