Just a short clip of my fastest lap from yesterday. Still a slow street car, but she sure is fun!

ChaseCam mount on the hood - unfortunately some wire has gone loose in the camera, so it only records in black and white now (IMG:http://www.frrax.com/rrforum/style_emoticons/default/sad.gif) I should talk to Randy about that and see what I can do. Panasonic DMC-LZ7 mounted to an IO/Port mount on the roll bar pointing at me - way overkill in resolution at the moment for filming my steering wheel, but technology sure has changed since I started recording a few years ago - this records at 848x480 to SD cards. A 2GB card (which is its max) will just handle a session. 1/4 the size and less than that in weight than my chasecam recording gear (old Sony Digital 8), no moving parts, and I can dump the contents to the laptop in 4 minutes. Sooo much better. If only it took video in as well =)

Hood camera is mounted on the right side, so video is offset. If it looks like I'm missing a left apex, I probably am, but not by as much as you think (IMG:http://www.frrax.com/rrforum/style_emoticons/default/smile.gif) Chasing down an Evo that's on mild R-compound tires. A couple clear mess ups on my part, so I have the potential of a 2:11, I think (he brakes way earlier than I do, and that was messing up some of my corner entries).

Enjoy! I'll put up a nicer video with text sometime within the next few days - it's been a long time since I put effort into my vids!

Sorry for the delayed thorough response. yay work and all.

0:02 I know! I was shocked when I saw that. I left that in so that people would yell at me (thanks!) and so that I'd remember that I cracked my knuckles. I still can't believe it. Hopefully seeing it so many times will help remind me that.

0:15 Very interesting analysis of T1. That makes a lot of sense - I go through T1 much faster than other people in my group, but I rarely seem to be able to capitalize on it for the straight between 1 and 2. I think my exit speed is suffering from my input speed (and early apex).

0:35 T3 scares me. More than once I've late braked into it and had the car rotate too much... so I take it rather cautiously (inside more and slower). I should try moving more outwards.

0:45 Yes, I miss that apex by a mile sometimes. My technique - finish 3, flick the car left, watch it understeer like a pig, and instead of fighting it, just nail the throttle. It drifts nicely through the corner and out to the berm. Definitely not the quickest, but keeping it from understeering requires settling the car before turn in, and that felt slower to me overall.

0:49 I hate pitching it over the bypass!

0:55 But I guess I need to pitch it so I have a better entrance to 6...

1:01 I love 6!

1:13 Yeah, I'm trying to drive over the berm. Sometimes I miss it a little. For 8, I generally take a set and then let the car carry itself through - it's going to fast for me try things, and the entrance always upsets the car a bit (that nice concrete patch they have there...).

1:21 Yeah, the evo's line through T9 was freaking me out =) I generally carry it a little bit further out to the berm, but he brakes much harder for 9 than I do, so the car didn't slide out as much as I expected.

1:27 Yeah, I'm pinching this exit. Mea culpa.

1:35 No CD's - I think that's the camera in the console ;-) I forgot to bring the shirt I normally stuff in there with it. We should fab up a mount, or something ;-)

1:43 The barrels are scaring me! I tried this time - I've never driven on the yellow before this.

1:49 Sometimes. Not this lap, though. I'm not consistent here.

2:04 Yeah, I'm hitting the apex here. I could swear I can feel it dip down a little bit...

2:11 This is one of the scarier parts of the track for me - the car was often getting loose coming out of 15, and I've seen people spin to the wall. But as the day went on, despite the car getting looser elsewhere, this turn mellowed out. I wasn't taking it slower, I think just better...

I have off of work on 7/20, I'll be signing up shortly (IMG:http://www.frrax.com/rrforum/style_emoticons/default/wink.gif)
