Im having a hard time trying to locate the transmission gear ratio's for a JDM FD. i've searched long and hard on here but all i find is talk about R&P ratios.
Google just fails

me and my buddies are having a friendly little GT4 time attack battle and my fd needs the ratio's of the jdm tranny since it has Fully Customizable tranny.... i;ve tired every automatic setting and a few of my own, and it doesn't feel right to my preferences.. i'll be running a 3:9 ish final drive ratio
with a long 6th

the track we're running is the 'Ring. i;ve got my car down to a 6:46 but it tops out at 178 well before its time to brake at the long straight. and on most of the sharper turns neither 3rd nor 2nd will do.... it either understeers or is way too slow for the turn
