The friction circle analysis will help you understand why this is so.
ALL cars have to understeer to initiate a corner. Understeer defined is slip angles at the front axle exceeding slip angle at the rear axle. That's what understeer means. What I'm complaining about is this car doesn't understeer enough to put its modest power down, proved conclusively by its hopeless winter handling. Actually, it didn't really work well on any road surface but with good enough tires to overwhelm the torque it can be made to drive fairly well on dry pavement.
You will note that the BRZ has positive camber at the front axle and negative camber at the rear. The front bar is 18 mm while the rear bar is 14 mm and the spring rates generate understeer.
The way in which Toyota got this car to oversteer under such modest power is interesting but it's not because the chassis isn't set up to understeer. It just isn't set up with enough understeer.
Anyone bandying around auto cross, or even to some extent track conditions is missing the point of this thread completely.
Gosh this is fun, like shooting fish in a barrel ....

I really hope (for your clients' sake, if you have any) that you're better at checking facts for anything going to a court room than you are at checking facts about cars.
You can use big words all you want, but at the end of the day it doesn't change the fact that you have absolutely no clue what you're talking about.
