The OFFICIAL: Auto-X Video Analysis thread

[Kostamojen]

Ok, the purpose of this thread is for folks to post videos of their cars in action (can be in-car footage) for people to view and analyse.

Please include the specs of your car, along with your lap times, and event results if you wish along with your video footage.

Responders: Make sure to mention which video you are addressing (in case this thread gets large)

Anyway, thats it, ill edit this first post as needed...

well, I guess I am first off...

05 STi : strano fsb, WL 24mm rsb, catback, yoko advan A046 (stock off Evo), -1deg F camber (zero toe).

46.7 time that won STU that day (OVR). Major wish list item: camber plates and more seat time... slow in = fast out (repeat, repeat...)

Looked nice and clean. I could see the simular understeer to what I was having in my vids, where you have the wheel almost locked and the car under power and its just not turning.

You are behind and turn too late You are late into both slaloms.

-Tom
just my constructive criticism

[trhoppe]

Also, you can't analyze a "filmed from the side of the course" run

Thanks for the constructice criticism

anyone care to elaborate further... im sure my driving can be throughly critiqued

[Scoob5555]

Me next!

Click me In-car video of my best run at the SJR event at Atco Raceway a few weeks ago. A double-looping course with FTD at 44.6 s (in an SM2 Miata). My time: 47.0.

Car is my 96 LX (automatic!) with 16" WRX wheels and Hankook 215/45-16 R-S2 tires. I have D2 Racing coilovers and an adjustable Whiteline RSB set to 22 mm. And Perrin end-links all around. Camber Fr: -2.8* Rr: -2.0-ish* and Zero toe all around. Only other mod so far is a CAI. Brakes are stock and terrible, especially with my left-foot braking. Trying to get some EBC RedStuffs to fit now.

More vids here.

I agree with Tom. Setting up a little late (or not at all) for a few of the turns, and then turning late. Reduce understeer by setting up your turns then executing earlier. Carrying less speed into those turns will also help (go slower to go faster). Overall not too bad, but more neg camber in front might help a lot. How much camber in the rear?

Listening to the tires it sounds like you were over driving a little bit. Squeal is good as that is the sound of a street tire at the limit, squal is bad, especially when you hear it chatter.

Tom is right about both slaloms.

-Paul

my mantra... be smooth, look ahead.

ive got stock rear settings (cant really adjust it much at all) which is -1.4

[trhoppe]

These guys are right on the camber.

1) Slow in fast out, look ahead, setup your turn
2) Probably 0.5s per slalom lost on entering late and too fast.
3) You aren't looking enough ahead from what part of you helmet you can see in the video
4) Get more front camber

My analysis: Took the first turn after the slalom too fast everytime, should've went wide then late apexed to set up for the little two cone slalom before the big 180

Too fast into the 180 and bad line. Needed to get wider and late apex the 180 cone as well.

Wider on the last turn around and slower to setup for the slalom better.

Any more opinions that I missed?

Mods:
230 whp/ 220 wtq
Tein Flex 8/10
Strano front bar
Perrin rear bar at middle setting and endlinks
-3.5 front camber/-0.5 rear camber
A bit of toe out front, none in rear
235/40-17 Kooks.

[trhoppe]

The music is way distracting from trying to actually look at the video. You have any other video?

-Tom

[trhoppe]

OK, turned sound off.

Late doesn't describe how late you were into a couple of sections. You didn't START turning until after the cone.

Actually, you did that everywhere. You are getting to the cone and then turning. You should be turning and already setup and commited before you get to the cone.

Probably had 2 seconds per run lost with that.

Slightly OT, what equipment is needed to mount a camera in your car, and how much would it cost?

My buddy is a wedding videographer, he has a $4000 HD camera. I wonder if he'd let me record a few auto-x runs in 720p

[AndrewSS]

thanks for the feedback, yeah I really got to learn to look ahead - I think that will help me sort the line and how much speed is proper for the corner, etc... test n tune on saturday, I plan to have some more video...


corn-picker, well you need a proper mount, especially if you use such a nice camera

check out www.chasecam.com to see if any of those solutions would work!

[WRXbluJ]

When I get home tonight I will edit my videos from last Sunday and post. I am still amazed at how much I learn from watching the in car video over and over again.

A couple of weeks ago I kept having a (real) hard time with a right jog after the first slalom, you can see where I go to turn in and then have to turn back to the right.

This is only about my 10th AutoX, but I did RallyX all last year. I have learned several things and now I realize why people mod their car to be in a certain class - that is what I am going to start doing now, just exploring my options - I need to sift through the confuzledness that are the class rules and put myself somewhere nicer

No Suspension mods (I do have pinks waiting to go on), Turbo back (catless), intercooler hoses, bov (the only thing putting me in SM, I beleive so that is going away), BFG G-Force Sports on stock wheels, SS brake lines, AP Sg2

Not looking ahead is the root of most of your problems. Some of the runs you were late in just like Tom said, some you weren't. Car placement also seems to be an issue as well. All of the proper looking ahead and good braking and such in the world won't help if one is a full car width too far out on certain cones. I didn't listen with sound so I have no idea just how hard you might have been pushing it.

[IBAUCLAPlaya]

Thanks Tom and Biggly. I'm down at Cooper Stadium for OVR this weekend, I'll make a video and try some of those tips and see what happens.

[AndrewSS]

^ heh, I will be there saturday (mothers day sunday so I cant show) looks like its gonna be rainy...

see ya there

[AndrewSS]

here is my incar from earlier today:

dont bash me too much for my pooooor driving in the rain - well atleast what I show in the vid is bad, the last few rain runs after the two I show in the video I clean it up A LOT.

The last run in the video is from the afternoon session, it was pretty much 100% dry out, damp in a few areas though, but the line was pretty well dried.

I have to mention that, although the last run was the fastest for me, I believe that run its possible my pressures increased and/or my tires (stock off the Evo) just over heated some from running them without a whole lot of cool down, I say this because I got some weird push in the turns 3-4-5, even though I was driving the same as last run OR even a bit more conservative, so anyway you will hear the push there - but I think it could be attributed to my tires pressure/over heated... I just didnt really expect it. But overall I am pretty happy with the run.

[Scoob5555]

Here's mine from today. I was winning the class all day. Until my nemesis knocked a full second off his time on his last run and pipped me by 0.30. Drat!

Overall I was pleased with 5 of my 8 runs. I tried a few things differently throughout the day with my line, but the video shows not only my best time for the day, but also what I worked out was the best line whilst carrying as much speed as possible. My last run had real potential but I pushed too hard and coned. Brakes are still my major limitation. I hope to rectify that this week.

Please have at me and let me know where I can get more time. Thanks.
