Regardless if it is power sliding or not.
Honestly you should start by putting
Torque converter- 10/90 split
LSD- Front 5/5/5 (put the rear at something you are comfortable running. I would use 5/60/60)
The reason for setting the torque split at 10/90 and the front LSD to 5/5/5, is to make it more/closest to a RWD. It will be more realistic for drifting that way.
For a suspension
Run say,
Ride hight
Front -7 Rear - 15 (creates oversteer)
Spring rate
Try to keep it low. I usually run maybe one or two points above the minimal spring rate. As a example, if the lowest you can go is 3.0 on front and rear. I would run somewhere around 4.7 - 5.7 in the front and 3.9 - 5.2 in the rear.
On dampers
Extension- 1 in the front and 4 in the rear
Compression- 10 in the front and 3 in the rear
Anti-roll- 1 in the front and rear
Alignment
Camber- 3.0 - 3.5 in the front and 0 in the rear
Toe angle- -1.00 in the front and +.20 - +. 50 in the rear.
