both of my auto supras have had a 4.30 open diff

to figure it out, you make a mark on the tire.

spin the drive shaft until the mark makes one complete rotation and count how many times the drive shaft spun.

well i've also heard that if you got a certain package you could get the 3.73 for highway traveling.

Cause why would you wanna go 60mph at 3000 rpms for a daily driver...i do it...but it's kinda loud and i'm around the city, so 60 is the max speed i drive.
