Default Talking about gears.

The OEM pinion has 10 teeth, ring has 41 teeth.
Ratio 10:41 = 1:4,1000

Richmond 4,57-R pinion has 7 teeth, ring has 32 teeth.
Ratio 7:32 = 1:4,5714

The first batch of Richmond gears are refered to as 4,56's.
There are also 4,44 and 4,77 sets used in S2000's.

What are the number of teeth on those ring & pinion sets?
Just curious

4 digits after the decimal "." would have been enough.
