Hey all. I edited some of my race footage from the "I got your stimulus right here" regional and pulled out three clean laps at Limerock. Anyone want to offer up some help? My fast lap that day was a 1:05.1, and it might have actually been the last lap in this sequence.

And if anyone wants to watch the 9 minute summary of the weekend video for some reason, I've got it here, with a soundtrack from my friend's band:

Vik,
I'm Jared Lendrum (I am using my father's login since mine hasn't been approved yet), I ran SM in the stimulus regional. I finished 4th, with a best lap of 102.4. I have a few iems of advice based on your video.

First off, use the whole track. You have some areas pretty well figured out, but there are two areas that need work. On big bend, it seems that you are staying too tight. Many drivers will "double apex" big bend, giving themselves the ability to maximize in-corner speed as well as exit speed. You should carry some more speed into the corner, then about half way through, you should "turn in" and aim for the second apex. In an open track situation, I'll even set up wide, skipping the first apex in order to maximize the corner exit speed.

You also need to work on tracking out on the uphill. The ammount of traction that you gain when your car hits the face of the hill is impressive. I actually set the car up so it looks like its going to track out directly into the flag station. Once the car hits the hill, you can use the added traction to carve your way back to a healthier track out line. If you do this right, your car should break the rear end loose at the crest of the hill.

I also noticed that you tend to turn in early on both the downhill and in west bend. Its very tempting to do this, especially with the adrenalin pumping, but its bad. Focus on turning in later, and apexing later so you can track out without lifting. There aren't many good marks to use in the downhill, so you have to just feel it out. In west bend, I use the RV access road as an apex mark. After getting a feel for this you can work on braking later and
attacking corners with more speed.

One of the most important sequences of the track is the left-right. It looks like you have that figured out, so for the rest of the track, just work on turning in a little later and using the whole track.

I hope I was helpful and wasn't too redundant. Good luck next week. If we are there, dont be scared to stop by.

Thanks Jared. Much appreciate the help. Hopefully I'll be able to apply some of this to the school and my races next weekend at the regional.

Will keep an eye peeled for your car/family at the regional next week.

I second the talk about Big Bend - you are braking early and staying too tight. If you come out wide in the middle of the turn (i.e. you are carrying more speed through the first part) before rotating the car in for the second apex, you make it a later apex and can accelerate harder off that corner.

To carry more speed and brake later...point towards the first apex right before braking like you are doing, and then drive/drift past the first apex, you almost aren't turning until you get just past that apex, it's a weird feeling. In order to brake later, you need to be braking as you go past the first apex. So naturally you need to be pointing straight/as straight as possible.


You are braking very early for the uphill. All you need there is a quick stab of the brakes, then accelerate immediately on turn in all the way through the turn. Track out like mentioned, the car will hold.


West bend is also a little slow- you are braking a little too much, but this could be a product of your early turn in as mentioned above.


Other than that I thought the laps were very smooth and clean. Nice job

Dunno if I'm driving the ideal LRP line or not but I'm learing some things from reviewing my videos from last season. There are a few of my LRP vids on vimeo if you're interested.

Just uploaded this vid today from the NARRC Runoffs qual session. Man, my bent car didn't like the downhill at all. You can see it hopping through the corner: http://www.vimeo.com/10094311

That's how I roll Mr. Longo. Man, you sure dropped anchor going into Big Bend there eh? You're supposed to use the pedal on the right, not the middle one [yep]
