2 69.25
3 103.70
4 146.59
5 164.06
6 188.14

1M 6spd 7000 redline

Gear Max Speed
1 42.59
2 75.62
3 113.52
4 156.59
5 175.05
6 206.92


Note: I did not factor HP into the calculation. Simply based on gearing
The M3 looks right, the 1M looks off. What final drive did you use? For the 1M w/ 7000 rpm I get:
1 41.0
2 72.8
3 109.3
4 143.0
5 168.6
6 199.2
