maybe worth posting your acurrate ones up ;)

for an '05 JDM STi

1st - 3.636
2nd - 2.375
3rd - 1.761
4th - 1.346
5th - 1.062
6th - 0.842
FD - 3.9 (1:1 drop gear)

Speed = (rpm*0.07575)/(gear ratio*final drive)

The 0.07575 is how many miles per hour a 235x45/17 wheel/tyre does per revolution. If you're on 225's, then it's 0.07469 :)

If that US site is correct ;) does seem that on MY01-04 UK (2.0ltr) only 5th/6th are different ;) but thought the UK Sedan gearbox from 2001-2007 were the same.

I will modify my original post to reflect that :thumb:

Still not there. Those 5th & 6th gears are wrong for 06/07 models.
Perhaps the hatch had them changed again?

1st 3.636
2nd 2.235
3rd 1.521
4th 1.137
5th 0.891
