Probably the Audi... But neither are really viable for drifting on dry roads. I'm pretty sure the Mazda is fwd, and the Audi is either awd or fwd... So I'm not really sure
It's called "dragging ass" thank you very much. All you need is something set up like a truck... No weight out back and you will slide around a corner, did it in some icey/rain crap last night in a minivan.
people who know this little about drifting or cars in general shouldnt try drifting. You will just become a statistic.
