What variables do you select for the x and y axis to make things meaningful? When I select lat and long or vis versa for the x and y axis, I just get a plot that looks like a 2 year old with his first crayon.

Did you get that positive camber issue fixed?

Reefwalker

Not yet. I took a look at it on Sunday, but I'm going to wait until the weekend when I can do a more thorough analysis of the problem. I looked at some pictures that were taken before the track day and didn't see as much positive camber as I have now, but it's hard to tell from a picture.

G-G plots do tend to look like that. There is some skill involved in interpreting them.

Should look a bit like an acorn.

I'm not really sure what it is that I'm looking at, but ironically enough, it does resemble an acorn.

Hurray for MSPaint? j/k How do you read that?

mikegarrison

I read it as "he does a lot less braking a straight line than you do".

However, it is better to look at particular parts of the track than the whole lap at once.

Reefwalker

My guess is that the more vertical lines indicate longitudinal braking force. As you start to lift off the brake, the line should rise gradually, but veer to either to the left or the right (dictated by the direction of the turn and associated lateral forces) if you're trail braking properly. I imagine that if the angle of the line is steeper it would indicate less trail braking. However, I'll wait for the experts to weight in on this.
