project: dogbox transmission for st205 Options

[tufy]

Ater i had several transmisson proplems. i realized that i need a stronger one. i decided to build a custom gearbox. so i can decide for ratios. what would you chose if you build one?
here is some ratios

......................Standart...................fensport.............custom
1 st gear......3.38 - 57 Km/h.............3.58....................?
2 nd gear.....1.91 - 100 Km/h...........2.045..................?
3 rd gear.....1.26 - 150 Km/h............1.33...................?
4 th gear.....0.92 - 210 Km/h............0.97...................?
5 th gear.....0.73 - 239 Km/h............0.73...................?

Final drive 4.285............................3.933...................?

can any one tell me what is relationship between final drive and gear ratios.
if gear ratio x final drive ratio is equal, speed is same.

those are thinks that i am planning to have.
*seq. Shifter

*new input and output shafts,
staright cut gears,
dog clutches,
hubs,
forks

*final drive (pinion and crown), front & rear


*front lsd
(not sure about front lsd, fensport is using stock one)
