Wow, that's a lot of rear pressure!

I'm using a different tire but I'm seeing pretty good usage of the entire tire at autocross with 25 psi and just a degree of camber. I wonder what's so different between our cars, it doesn't seem like tire selection would make that drastic of a difference.

I'm using 235/40/17 Zeknova RS606 (go on, get your laughs out now, I'll get better tires next time) in the rear.
