gear ratio's

[bimmernut333]

I'm just curious how can I determine my cars rear end gear ratio? I looked at the build sheet but all it says is 25% lsd. I know I could look at the tag or mark the driveshaft/wheel to do the spin test but is there any other way like a more in depth build sheet? The cars vin # is WBAAA2301H3111494.

THANKS,

Look at what it says on the diff.
