Note what happens to the Red Holden? (Looks like an opel but not exactly) he either downshifts and is 'fishtailing' all the way through.
How about turning in a bit later? Staying more left, you steer in way more early than i would much like the slomotion on this Mini
at 2:38 its the same turn. a late Apex would give you benefits in this turn (especially comming out of it..) if it is a 180 degree turn. The whole pack you are in is driving a defensive line!Much like the picture below (i love google)
Now dont get me wrong but you leave allot of track unused, so my advise use more of it! I find that 180degree sweepers are best taking with a late apex as it leaves room to weave out in the rest of turn, instead of fighting understeer.
In most of your corners you choose the 'Geometric' Apex, It's very common for drivers to apex too early due to nerves about the approaching corner and eagerness as described in your previous post, to take the turn. The racing line apex in this corner is further round the corner than you expect. (This is where experience and track knowledge come in, but it seems you know your way around it fairly well)
my advise Apex a bit later in some turns!!
hope it helps.. though i dont know the track this is my advise to try and see what gives. it looks allot like one of the turns on the ring.
Other than that you might try hurtling towards this corner, and you turn the wheel and find yourself ploughing straight on easing off the throttle (much like john said in braking more gentle) It will result in a forwards weight transfer which will increase the available grip at the front wheels. Hopefully this should correct your course. If you're already off the gas, then a light dab on the brakes should help.
Anyway i learned a great deal from sitting next to a pro who was very gentle on brakes steering etc... haha what John said !
