Transmission question:

If this is stock:
Gear / Ratio C150 5MT
1st 3.54:1
2nd 1.90:1
3rd 1.31:1
4th 0.96:1
5th 0.81:1
Reverse 3.25:1
Final Drive 4.31:1

and this is TRD:

Part number : 33030-EP702
Gear / Ratio C150 5MT
1st 2.786:1
2nd 2.059:1
3rd 1.600:1
4th 1.273:1
5th 1.042:1

Part number : 33030-EP752
Gear / Ratio C150 5MT
1st 3.200:1
2nd 2.359:1
3rd 1.850:1
4th 1.458:1
5th 1.167:1

If we wanted lower rpm's in 5th gear, wouldn't a lower ratio or is it higher ratio? Confused...

       1st                3.54:1                         2.84:1

       4th                0.96:1                         0.70:1
       5th                0.81:1                             –
    Reverse           3.25:1                         2.34:1
  Final Drive         4.31:1                         4.15:1

4. High numerical final drive ratio = very short gearing
5. Short gearing improves acceleration
