The Australian MY02 WRX has revised gear ratios giving greater in-gear acceleration. So much so that the MY01 gave a 6.9sec 400mt however MY02 does 6.2 seconds.
It's actually much faster than the MY01 when going from 70kms to say 130kms by over 2 seconds.
I read it in an Australian review.
The photo in the link above is for the Evo5 Club Spec which has been a model offered here for some years now.
Dodgey colour though.
