Personally I lost interesting in drifting a couple years ago, went to an event and it just didn't do much for me anymore. There is a pretty big even coming up 9/15 called Street Life Tour, both drifting and drag... payout for drifting is $5k, drag $14k. I'll let you decide on which one is bigger up here lol
