I doubt any of the mods did anything other than try to annoy the shit out of you on that thread, but I can tell you that continuing to whine about it is probably not the best way to get people to stop messing with you.

Since that test series was handy…here is a shot showing at the limit camber and tire patch behavior. Note that this is just another form of datalogging, one that is perhaps more accessible to more people.

The car is at full chat and still has about -1 degree camber up front. This maxes out grip. The car had about -4 static IIRC. The rear tires have moved into positive camber. Note the difference in contact patch/sidewall movement. These are 285/30 Hoosiers.

Similar concepts apply to any tire or car.
