I've been doing it since I started driving - but its not called for in most street driving situations where you have SOOO much time. I find no reason to jump onto the brakes as I come into a turn, Ill typically just double clutch then brake then turn in; unless I know no one else is around. Also there are so many speed bumps and crap on the road - i don't like to throw in unnecessary variables. What can I say I think ive become a square.
always done it, did lots of club racing when younger so always had the need. See it as second nature now and always do it on the road. Makes for faster smoother progress with less stress on my WRX's already fragile box.
Dabble with a bit of Left foot braking too when the need arises!
Its pretty hard to see in the video- its pretty frenetic... but i think the :44 are singles and aroudn 1:57-2:06 those are dbls.
I'm more curious as to why he stabs the clutch under brakes without HnT, is he trying to get a more aggressive trail brake/slide by unsettling the rear with a shiftlock? i really want to try driving fast now.
