Eh, I think people who whine and complain about AWD car is not consider drifting needs to relax eh. This is a game, you suppose to have fun with it. Not having debate in a forum about who is better, what car is better, or who has more skill, this and that. Where is the fun in that when you can just spend the time and enjoy the game.
As for that wikipedia definition of drifting, it never mentioned what kind of drivetrain MUST be used to consider drifting.
"Drifting refers to a driving technique and to a motorsport where the driver intentionally over steers, causing loss of traction in the rear wheels through turns, while maintaining vehicle control and a high exit speed. A car is drifting when the rear slip angle is greater than the front slip angle prior to the corner apex, and the front wheels are pointing in the opposite direction to the turn (e.g. car is turning left, wheels are pointed right or vice versa), and the driver is controlling these factors."
Reread again...drifting is a driving technique. It's not depend on the car you use. People need to learn how to read and interpret a sentence properly before laying down some senseless argument.
another quote from wiki
"Usually, drift cars are light to moderate weight rear-wheel-drive coupes and sedans over a large range of power levels."
Should I have to emphasis that in that sentence it said "usually", not "must be". Hence for those who kept arguing that AWD is not consider a drift or drift = RWD, you can dismiss your argument.
And last but not least, the guy is asking for help in his thread, not ask you to debate about the drivetrain of a drift car.
Anyway, I have no idea how to set up an AWD car for drifting nor am I an expert drifter in GT5. Just I see a lot posts on GTP people arguing about AWD is not drift and blah blah...but yet none actually given a proper proof stated that drifting MUST be a RWD car. So word of advice, relax and enjoy the game, everyone will be happy.
