Have you ever noticed a little extra eagerness for your car to turn in when you get off of the brake pedal at the end of your trail braking? Same thing can occur in situations where you'd have been at 'maintenance throttle' in a turn that decreases its radius slightly, except that it's a much milder effect than getting off of the brakes. For me, that was noticeable when taking NJMP/Lightning's T2-T3 sequence as a single corner where lifting was enough to help get down to the apex of T3. Roll steer is also involved, as the rear of the car will rise (roll steer moving in toward oversteerish, aka "loosening"), and I was losing this with the stiffer rear springs and lower rear ride height.Off throttle turn in, is that completely off the brakes before turn-in?
I ask as I tend to keep some brake pressure as I turn in (trail brake).
Most other turns, it's coming off the brakes that works in stronger fashion.
Lifting off of either the brakes or the throttle momentarily leaves you with a little extra front tire load without any of it being used for longitudinal traction demands (trail braking) and when timed right seems to help an understeerish car.
