Just finished a good lap with the 3000gt vr4 turbo´99 in grand valley east section. Maybe not the most effective or fast drifter but definitly fun to drive sideways.
You didn't do anything wrong posting here, but I wanted to let you know there is a Drifters Only forum as part of the GT3 page. GT2 discussion is welcome there as well and you may get more response.
Tigra Ice race car. Great car all around. You can get grip or drift driving out of him and both are really cool.
Audi S4 and tt LM. Great drifters; both have the power to keep pulling instead of dying down and the tt is just amazing to drift in slow OR high speed corners.
