Most of the time with hands and 8 and 4.
This is more relaxed than the silly 10 and 2 and places my right hand on the wheel as close as possible to the shifter. Shifts can then be made by lowering my forearm and flicking the wrist down. My upper arm only needs to move for pushing the shifter away from me.
When approaching a corner I position my hands on the wheel so that they stop at 8 and 4 at the turn’s apex for maximum control, also my right hand is again close to the stick should I need to shift in an increasing or decreasing radius turn or if the hack in front of me decides to brake midcorner.
Holding the wheel from inside the rim is a great way to get your arm broken should the airbag deploy.
