Drifting on dry pavement is MUCH harder than on dirt or snow, there really is no comparison. There are basically two methods to get the rear to come out: emergency brake (used a lot) and breaking the tires loose (often by 'kicking' the clutch). The sport is pretty hard on the drive train, not to mention the tires. And that assumes you stay on the course, and often you don't (when your running a real road course track).
I would give it a go on WET pavement, which is more like dirt or snow, but I'd never drift my ERA on dry!
I've drifted a bunch of different cars, the Cobra was BY FAR the most difficult to KEEP in a controlled slide and the easiest to get a slide started. The back end wants to come around, and it will with little or no warning, very touchy car. It's a terrific 'spectator' sport, I'm going this weekend to a drift session, just to watch.
