Need a little help figuring something out

[SSLance]

Ron,

I've got planned to get the car on the lift here at the shop Wednesday morning after a car show tomorrow afternoon. I've got the part numbers of upper ball joints and hope to get them measured at the parts house on the way home tonight.

A few observations & tips:
0:24 Keep the late apex, but increase your degree of turning to end up with a lower, straighter exit.*
0:36 Use more of the track. Let the car "eat" by running a larger, gentler, wider radius to the outside of the track on exit to carry more speed.
0:38 Straighten out this section ... to be closer when you clip by the inside edge ... then wider when you get to corner entry.
Cone Esses: You're a tick behind in your steering making you have to turn more.
1:03 Use more of the track. Let the car "eat" by running a larger, gentler, wider radius to the outside of the track on exit to carry more speed.
1:14 Keep the late apex, but increase your degree of turning to end up with a lower, straighter exit.*
*If the handling will let you.

If you watch in the carousel, you can tell it is sliding the fronts almost all the way through. Still a fun drive though.

Cool !


Was it really 75 degrees there? It was 108 here!

Thanks for the tips Ron. What I was really concentrating on was to find the line that got me through the tightest sections of the course with the least amount of steering input (knowing now how much more camber loss there is with the increased steering input).

For instance, during the pace lap I figured out that the large carousel near the beginning was just about the exact same radius the whole way around, so I found the line that got me through it all basically without moving the steering wheel at all once in the turn. I tried to control how it came out onto the next straight with the throttle not the steering wheel.



The run before was better in that section, but I really struggled with that next section finding the right braking spot to not leave too much time on the table while at the same time not wheel hopping under braking. I left some time leaving the carousel because I was thinking about how to set myself up for the end of the next straight.

I know I was behind every time in the esses, again I think it was because I'd upset the car before that first gate getting into them. In fact, I got scored with a DNF my first run (erroneously which they fixed after) because I went right at the first cone instead of left. I was about halfway thru the esses when I discovered that I was coming out pointed the wrong direction for the entry into the Chicago box (another rookie mistake).

#1 dealing with the hard braking zones and then #2 dealing with a going away right front tire really made for some less than satisfying runs for me. It was fun still the same, but I just wasn't getting the results I wanted.

And yes, it really was 75 degrees... Was a beautiful day for an autocross.

Ron,

Aw man ... we were BAKING ! Still are. 5 days of 106+ temps.

What about the lower ball joints?
