Well, I just want to offer some advice and encouragement to all newbie GT4 drifters out there.
I am a newbie drifter myself, but thanks to the friendly people on these forums, and the setup depot, I have shown 300% improvement in about an hour and a half. Still not up there, but getting there.
I started with the Monaro (as I am Australian, and a Holden fanatic), however I found it to be too whippy and tempermental to control as a first drifter. I am now using the '88 Silvia K's tuned as per one of the setups (i forget which) on this site. I am practicing on Motorland, and seem to be getting the hang of it quite quickly, using the throttle control method (it's the only way i can stop the flickback on exit). I have gone around every corner sideways, although, not all in the same lap. I am yet to complete a lap without either just driving off the track (unintentionally), or sliding/spinning off.
To other newbies out there, the age old saying (which has also been repeated here umpteen million times) "practice makes perfect" really does apply here, so keep at it, and if you start to get frustrated, take a break, clear your head, and then get back to it. If you stuff a corner up, just think to yourself "I will try again next lap", if your corner is a bit sloppy, think "next time, I'll nail that one". Besides it's a game, it's meant to be fun, so have fun!
Okay, rant over
Thanks everyone, you have been a great help!
