The truth is that amatuer drift cars (slammed and flush) have horrible suspension geometry and travel, but the look of a drift car goes hand in hand with the culture. We usually don't care if the car is bottoming out, or if we are getting tons of bump steer, or if we are running unuseable amounts of camber. As long as it looks good as it slides, that's all that matters.
When competition and money is the subject, such as the case with the pros, looks are just an advertisement. Winning is more important. Making sure your tires are correctly contacted to the surface of the track is essential to any motorsport (even competition drifting).
What the guy says in the article is all true, but he missed something. Some people, like most of us on here, want our cars to look awesome, no matter the loss in performance and comfort. We just want to be able to drift and look good, and that is something that I felt he disrespected.
