Alrighty.
To start off, e brake drifting is something that Fast and Furious made popular. Which is never the way pro drivers actually drift unless it's rallying and then they have hydraulic e brakes for that (Ken Block). But, even then he only uses that trick a little. So, most get a RWD because they can spin those tires and slide the car. Doesn't necessarily work that way for a FWD. Not saying it's impossible, just a lot more challenging. And to boot, doing this will wreck your e brake and potentially more. Your buddy with the BRZ is going to have a really expensive bill. Don't know why when he has a RWD.
That said, if you really want to e brake drift your car, it's your car. youre going to need to go into a turn with a little speed and then pull it. Just a little! And either way you're going to have to use the 'lame' throttle to maintain it. Orrrrrrrrrrr, you put a pair of crappy tires on the rear (or all around). You could even put on drifting slicks.
And the REAL way it's done, is by maintaining a speed of let's say 30 in a circle just to start, pushing in the clutch to let the engine rev high and then releasing it fast and let the car slide.
