drifting with manual steering

Hi all, would like to field a general discussion about drifting with no power steering. I removed mine after losing the battle to keep fluid from leaking out of various points in the system. my first shakedown without power steering proved that it is indeed a burden to drift with. I am also running ~7deg of caster up front now which I believe to be excessive now, the car self-steers at the speed of light and it is almost dangerous trying to catch the wheel. This is also in conjunction with a 320mm steering wheel, my plan moving forward is to reduce caster to a ~4deg and get a 350mm momo. I would like to keep p/s off the car for the sake of simplification, so I'd love to hear how others have set up their cars without power steering. thanks!
