I run drag brake always . the reason I run drag brake is because back in the day when all I raced was stock when you let off the gas the motor had so much natural drag that is would slow the car down quit fast so you could run a few more clicks of throttle trim or just deal with it. So over the years I have always dialed a little drag brake into the car.
As far as extra heat and extra wear on the brake in my experience this is never a problem. I mean like the guy a few post back saying he wants his car to roll free threw the center of the corner...... I dont now were you are racing but if you are not back in the throttle by the center of the corner were I race you would be traffic....
