What I found very helpful when learning to fly was being taught that every turn was an ACELERATION.....
Not immediately obvious but if you think about it is logical. Those of us who are taught aerobatics appreciate this more but every level turn involves an increase in angle of attack and with it drag. To counter the drag more thrust is required to maintain airspeed and if airspeed is lost so is lift and hence you descend.
If you instinctively add a little power as you roll into the turn at the same time as you increase pitch, then the turn stabilises without loss of height and (if you have enough power and limit the AOB) you can also maintain your initial airspeed, and with it the lift you need to stay level.
The same is true in a car. The deflection of the front wheels to turn increased their rolling resistance, if you gently add power in the turn (assuming you have entered the corner at the correct speed!) you can "feel" the car in much better balance. Slowing in the turn is bad as it loads the outside front wheel while lightening the load on the other wheels, which in turn reduces their grip......
Just my 2c's.
