Drifting
No issue for wheels with curbing at njmp with a softly sprung race car like mine, especially with the fat sidewall tires... (This will change effective next race with bigger t-bars and lower profile tires I am sure) Some other tracks are another story. Curbs at 1, 2, 4, 5, 7, 8, and onto the front straight are benign and jumping them allows for faster times imho. 3 is tricky... You have to put half the car on the inside of the curb otherwise the curb will push you to the left badly... Very smooth and composed driving Cello btw.

Thx, Fred.
Of those, I am comfortable with 2, 5, 7, & 8 (no chicane). I can do better on all, but I think I have to get over and onto 4's curbing (at apex) a bit more, and ditto with 6 (at apex). I do think being a little later and sharper on turn in wld help for both turns.
T4 - i am just not braking correctly and therefor starting the turn at different spots each time - I try to do a quick stab b/t braking marker 2 and 1 (no chicane), then wait to turn in (which is not yet consistently located), and throttle thru apex. What shows is a wk in progress hence the slowness.
T6 - is an optical illusion for me. It just looks like you are running out of track, but there is room there to go deeper then i do (see the Acura and his turn in spot compared to mine). I think I need to straighten out that turn a bit by being a little deeper and crisper on turn in and then on throttle thru apex. I feel like i am early and coasting to apex there b/f I can get on the power again.
I got a ways to go I know......

Good discussion!
I'm responsible for the curbing placement at Thunderbolt and a lot of this commentary is right on. I'm contributing to a thread on the same subject with some relevent input at Bimmerforums. See http://forums.bimmerforums.com/forum....php?t=1424722
Looking forward to reviewing the video.

Lots of early apexes. T2 you are early every time. Going thrugh the chicane, you need to hold the left hand longer, so you can get a better run on that straght so you only need to use the curbing at the end of the trackout there. It is such a common mistake, and when you get it right you will be able to catch everyone in your run group. The following right sweeper can be taken with so much speed. There is PLENTY of track-out (you and most never even track out to the left 3/4 of the track there. Go in Hot enough where you have to once and you'll see how much speed you can carry into that sweeper.
(I instruct @ NJMP so I know it just a bit)
Too bad you cant alter the fish eye on the contourHD, and dissappointed with the sound. Was thinking of getting one and I think just made my decision on the GoPro HD

Dave M, thx for the comments.
I hear you. At my level, consistency is the biggest issue. Bob gave me a good tip herein re thinking in terms of where i want to end up after braking which i think will help me control speed/turn-in location a bit better (rather than trying to judge the correct amt of braking at the initial braking point). Re the chicane, you are absolutely correct, same thing Dennis Macchio told me at a BR 'Drive your own' event there last year. As it was, I held it longer than most in that run grp so that is a common mistake.
Re the Contour, don't decide from this. First event out with it - learning. Sound is bad as it is basically over the back seats (stock car - no harness bar) so it is hugely getting wind buffeted. I think sound would be better if set b/t the front seats. Also, used it at 760 (720?)/60fps setting not the 1080/30. Will try the higher resolution at Schattenbaum's April event and if better quality I will let you know. That said the GoPro HD is great.

It would be great to hear the a designer's thoughts on how to attack the track ...
[OK just found those comments in post 5 of your link. I wld LOVE to hear your critique, Peter.....Thx]
