Just completed my first Auto-X event ever and I had a blast! I went in the Novice class for my first just to get the hang of it. Definately noticed that my Yoko ES-100's wont cut it for much longer, the sidewall is rediculous! Anyway, just wanted to show a couple pics:

Look at the sidewall!

Soooooooo glad I didn't buy a house in that neighborhood behind the fairgrounds. Was looking at building in there about 9 months ago.
Good place to autocross though.

 

That was a great track over the weekend, fast and pretty smooth, anyone see that Mustang take out the timing lights?

 

Saw the mustang, he killed those timing lights then proceeded to almost hit a tent full of on lookers. I agree, very fun and fast track... The start was kinda wierd, a direct 90 degree left turn.

 

Yeah the start was pretty wierd but I liked it. It kind of made the setup for the straight after that fun.

we had one of those 90 degree starts at a Detroit chapter Autox. Defently helped the rwd people out.

What did you set your tire pressure at? That much sidewall flex looks like they are underinflated for that kind of driving.

 

I was at Barber so I didn't see the course, but I was told that there are a few reasons for a start like that.

1. It adds that extra bit of complexity to the course. You have to set up your start on the correct side and you have to hook up pretty quickly.

but, most importantly,
2. It eliminates the "drag" start effect. High horsepower rwd/awd cars have little advantage over fwd on a start like that. They spin too much and are super loose.

Makes sense to me.

Defently. Normally, you can set up so that there is very little turning involved, and you basicly just try and apex the corner cone.

38 psi front, 40 rear... Is that low? I heard the ES100's have a soft sidewall but thats almost rediculous.

 

I would try bumping them up even more. Have you ever heard of chalking your tires? That will help you determine the right pressure.


baicly, put some liquid chualk on a few spots on the tire, going from just slightly to the normal wear spot (flat part of tire) and maybe an inch or so down the sidewall. When you have alot of tire roll over, it will wear the chalk down, and you'll know how much. Add more pressure until you get the wear pattern to the little triangle on the side of the tire. (look on your tire, its there)

 

Hey Ryan, glad to see that you got that first event under your belt. Your 4th run was very respectable, not bad at all for someone who's never been out on a track before. You'll feel more and more comfortable with each event that you do and the times will start falling. Hope to see you out on the track again soon.
