Cobra max cornering capability

[HSSS427]

Took my ERA 427 Cobra to Road Atlanta yesterday for a track day. I also had a G-Tech accelerometer device in the car and was looking at the results on my PC. Was wondering what the max cornering capability is for this type of car. I know there are lots of variables, but would be interested to hear what experiences others have and how you can actually measure what the limit is for a car and set-up.

I guess my ultimate question is to understand how close to (or in my case how far from) the limit am I driving? As an example, I noted on some laps I took turn 1 at .8 lateral g's, and another lap up closer to .9 g's. If the car's limit is .95, then I feel I was pushing it pretty good. If it's 1.2, then it's clear I'm getting no where near the car's capability.

Also interested in any tips on how to properly assess the information from the G-Tech to determine which numbers equal the fastest times. And also, what would be the first things to look at from a car set-up perspective to improve handling. Of course, the first thing to improve is the driver's skills

FYI - car is an ERA with a 427 side-oiler, Tremec TKO 600, Goodyear big letter "stock car special" tires, front roll bar, Jag rear suspension, with dual coil-overs. Weight with me in it is 2930 lbs, and considerably less with me out of it

Thanks!
