Video Analysis, anyone?

So here is a clip of my fastest lap:

Here is a lap where I was cleaner, took a better line through the left hander, but somehow was nearly a second slower?  Could tire temp have anything to do with this?  The fastest lap I ran was at the end of the session, but this lap was at the start.

It appears to me that I carried a lot more speed through west bend and into the final corner on the hotlap. I think this has more to do with comfort level than with tire temp maybe.

[L.O.]

Seems that you simply carried more speed on fastest lap; I don't know nothing about Lime Rock, but I think you should try to late your turn-in point on turn#1 and on left hander. Maybe this can bring more comfort to gas earlier. Sometimes the better line is not the fastest one. Keep your smoothness!!!

split the lap into 3 or 4 sectors to more easily determine where you're making or losing time

Get a data logger. Done.

Some early apexes? On the other hand, how many apexes do 1 and 2 HAVE? Just getting THROUGH the Diving Turn without a Security Blanket lift seems an accomplishment to me. Lime Rock must be one of the best "club circuits" in the country--looks like huge fun. If you're on street tires (not HSAX stickies), who cares about the times anyway? The point is hits and giggles, getting smoother, faster, and more confident as the day progresses. There will always be somebody in a GT-R to blow one's doors off anyway.

My line through turn 1 is correct according to my instructors. You early apex and then swing out there taking it in a big arc til the second apex and then track out. Most of the corners at LRP are early apex except the left hander, which is very late. I am not far enough out for that one in either video.

Pilote--CLUB circuit you say??? we have an ALMS and NASCAR race there! No joke! :-)

Bradley--

As one who has missed many an apex, I bow to your instructors--and execution. "How many apexes?" was my attempt at a joke. I wouldn't have the faintest idea of how to drive the
1-2 complex--it seems to go on forever. Haven't looked at the video again, but was thinking of the Uphill and Big Bend, I believe. Again, I bow to you and your instructors.

As for "club circuit," I was thinking of the length. Don't know of another track of similar length as fast as Lime Rock. Well realize it is hard to drive well, and CRAZY fast. Watched an IMSA race there years ago on TV that remains seared in my memory. Al Holbert's co-driver in the Lowenbrau 962 was Derek Bell. He put EVERYTHING on the table through the Downhill, lap after lap, kicking up dust with the left rear on exit. "He won't get away with that more than once or twice," I thought. Wrong.

Neatly done. You look relaxed and drive smoothly. A beautiful venue that I'm very familiar with. I always assume that the right hander at he bottom of the hill must be pretty scary.

Some thoughts, forgive the lack of any organizing logic:

- Remember to be as smooth as possible everywhere, but especially, as you're turning in; I notice a tendency to want to throw the car in abruptly, which makes your car mad at you. Very noticeable as you were turning into the left hander.

- Stop shuffling your hands. 9 and 3 - keep em there. We want to see those gloves moving in tandem with the wheel ...

- Turn 1. Try braking much later so that you're trailing the brakes well into the turn and only come off the brakes at apex, which as you say, should be early. If you're off the brakes earlier, you've slowed too much for the turn and shortened an already preciously short straight. Track out no more than 1 car length from the right edge of the track. As you start to turn into the second apex, breath off the throttle slightly and enjoy how that front weight transfer helps turn-in.

- Be very careful not to lift into the downhill. Your car won't necessarily snap on you like other will, but it becomes ever more important as the pace increase.

- Have fun, keep enjoying yourself out there. Great stuff, this sickness.
