Yup - Most corners I only brake for 2-5m in a straight line, and get the rest done while turning in. Never coast through any part of the corner - Kart chassis' are made too grip-up under throttle.
Going into the fast "loop" off the back straight at Rochester, I give the brakes a quick stab at turn-in, then ride the corner out on 30->100% throttle. It's SaaaWEEET ! !
