Funny you mention Ebisu. Based on what I've heard, if you can master drifting Ebisu South, you can take on almost any drift course. I'm starting my own little project on 1990s Nissans that are popular for drifting. I read 240SX, S13 Silvia, S14 Silvia, and while I'm not a Nissan guy too much, I at least have one drift car project done (the 2003 Pontiac GTO), thanks to the help of the Drift Settings provided for it. I forget which one, but I'll have to visit the GT4 drift forum more often if I want drift cars. You guys n' gals got me hooked now.
Like I told someone, this is the way I learned the ABC's of drift: initiation, execution, and completion. I think it pays to be an aggressive driver at times. If you are not in any bigtime competition, it is a good idea to do some practice runs on almost any tarmac course. What I try to do is brake into a corner, swerve one direction, swerve into the other direction, depress the accelerator in small intervals (to avoid spinning out of control), and clear the turn. I think GT manuals I've read discussed the drift for the four major drivetrains (FF, FR, MR, and 4WD). As you would imagine, mid-rear is the toughest. Since the engine is midship, you don't really get that pull you get from a front-engine setup. But done right, you can control the rear of the car in an MR car to pull off a sweet drift. I have respect for "Formula D" because it's the only series I really KNOW about. I am not too educated about the D1GP, even though the D1GP is much bigger than FD, obviously.
To me, personally, I'd want to see some drift competition in the next GT. There are some people who take sideways action seriously other than rally fans. Even if the drift competitions aren't perfect, I'd like to see some implementation of professional drifting in a future GT, if not this one. Otherwise, going sideways gets a little, well, pointless.
