As far as old cars/trucks go, I've only seen lateral grip test results posted by Mark Stielow's "Jackass 2.0" Camaro that does 1.15g on 200tw BF Goodrich Rival tires. A thing to note about modern 200tw tires- they're labeled 200tw just to pass class rules, they're much stickier than traditional 100tw track tires. So going by treadwear isn't a good indication of how much grip a tire will have.

Here is a list of cars and the amount of grip they have for comparison.

Yeppers. I follow many of those top tier 'Pro-Touring' guys. Mr. Stielow is one of the elite of that group & a super nice guy as well.

I 100% agree w/your assessment on using/going by the TW numbers as an absolute value but it's a decent indicator of where in the range it's supposed to be. Something around 200TW should stick much better than something w/a 500TW rating w/the suspension set-up being the same (kind of a Cliffnote version). I had 300TW rated Comp G's on our 4th GEN T/A. They were decent as far as 'stick' but wouldn't surpass 10k miles on the street.
