hehe, this is sortta funny... do you guys actually intend to "drift" an ls or sc??? they're too porky, the canter of gravity is too high, and the wheelbase is awefully long..
i've been a drift fan since i got my licence and have owned a handful of drift cars previously (mainly 180sx' and ae86 sprinters)... and still have one that im working on at the moment...
as for auto's, i don't really think you can drift auto's... sure you can get them to powerslide, but that's totally different to drifting... powersliding, you get the rear to slip mid corner, whereas drifting, the traction is lost and the sideways actions begines before you even enter the corner...
i find a mix of brake control (ABS vehicle a must for beginners) and handbrake action is the easiest way to have fun... btw, i've never drifted a corner beyond 80km/h... it's just way too dangerous at that speed... you just can't predict how the car will react.
for a left hander, head toward corner in third, brake hard, drop to second + rev match to keep it in the torque band (5k rpm from my sr20det was comfortable), feint right ever so slightly, then about 20m from the corner, hook a massive left, plant your right foot, then depending on the slip, handbrake + countersteer.... from there it's all about throttle control...
very hard to explain, easy to picture, easy to work out.... just find somewhere to practice your countersteering and brake control... also, the drift bibe DVD explains heaps.
i practiced on a grass paddock (private property) in my first ae86. have fun
