I brake to drift on long sweeping turns and E-brake initiate when I need to swing the back end out on sharper corners. As I said before, I do wish there was actual grip-racing ability, but I've made my peace with the system and don't fight it. I just use brake-to-drift to my advantage, speed-wise. So far I've found the best-handling car in the game to be the Aventador (in Race class, that is). The car just cuts through any situation like butter. It's a joy to drive. I've also learned that off-road builds have terrible understeer and in order to drive them on pavement, you need to pull the E-brake to get the rear end pointed in the right direction on nearly every turn.
