STI tranny..... USDM vs JDM

1621 Views 4 Replies 5 Participants Last post by  Guru
I have read that the JDM tranny has a taller gear ratio in 6th.... does anyone know if the USDM has parts available to change final ratio, or if the JDM tranny is easily installable on the USDM STI?
I havent seen the particular question raised, which surprises me, as I have seen almost anyother swap discussed...

So what's the final drive ratio on the STi?
