2020-01-10 - Miata rear differential gear ratios
I want to confirm I am reading this rule correctly.
4.7.8. Rear-end gear-ratios are open to all OEM differentials available for that year, make, and model or chassis generation (excluding specialty high-performance models not listed on the VPI table).
Does this allow us to run a 4.3 ratio in a 1997 Torsen differential since the NA generation had both a 4.1 and 4.3 ratio?
We are running a 97 driveshaft, stub shafts and half shafts.
I believe the 4.30 ratio was only available in the 1.6 NA and the 1.8 had 4.10 with the Torsen from 95 to 97.
So you can run it.
