gearbox change considerations - ratio's table
I'm considering change of gearbox on my AE86 and after thorough consideration i came up with 20+ different gearboxes with they ratio's.

Many info are still missing but i believe some of you will find this table useful. It's fully editable so everyone can contribute if can.

There is a "calculation" part in lower part, it's just needed to input circumference of tyres, max RPM of engine and final ratio if different than stock 4.3:1

Ford Type 9 Quaife internals:
1st gear 2.39
2nd gear 1.54
3rd gear 1.21
4th gear 1.1
5th gear 0.87
Definately needs 4.8 final drive minimum, probably better with 5.1
