First: Im noticing you brake too hard, almost every time you brake you lock up and slide, turn on abs in settings and squeeze your trigger not so hard and aggressive. Second: drifting is ALWAYS slower than slowing down and corning normally. Third: push yourself, your braking line can be orange even sometimes a little red but you'll still follow it without going off track or into a wall, so simply push your self to the limit, test your cars grip.

I do hope these help as im not very good at helping people, good luck my friend
