Watch Senna do his hot lap on Brand's Hatch on youtube. It's crazy how he can pivot the car to align better for the exit without losing speed. I think it was Jackie Stewart that said that he steers with his brakes and not his wheel. Yeah, a weird statement but I didn't really get what he meant until I accidentally did that to Turn 4.
Theoretically there's a perfect balance point between lifting off the throttle and easing into the brake where you don't diminish between either and can literally pivot the car around it's center of gravity. On mid balanced cars you can do this easier without initiating oversteer or understeer. For some reason I can only do it on Turn 4 and Brand's with the Caymen. Trying it everywhere else I just initiate a drift and scrub too much speed away.
