Very impressive idea, I had a feeling that Mazda or someone would put to use the mythical super-low 4th rear end ratio
4.3:1=43/10 (43 teeth on ring gear/10 on pinion) (GTUs only)
4.1:1=41/10 (FC manual)
3.909:1=43/11 (FC automatic)
3.727:1=41/11 (combined AT and MT gearing)
Since everyone in the 20B sector prefers a lower ratio to match the 20B's torque, perhaps this would better suit it instead of a 13b?
