there's no magical formula for success, so what I suggest may not work for you, but generally you want the following
soft suspension (low weight oil/soft springs.
mid or front mounted motor for balance
a fast/efficient steering servo
as much steering range as you can get without blowing cvd's
a little camber, at least up front
also remember that too much motor (power) can kill a drift easy. drifting isnt all about about a powerful motor. learn to control your throttle just enough to break traction pretty much.
