OEM Tire Pressure Recommendation Changed for MY2015+?

When I tried 36 and 37 psi, there was a noticeable difference, and not for the better. Also, when I tried 32 and 33 psi, the car felt like it gripped better while cornering, but the crispness of the steering was sacrificed, and it felt "mushy."

As for using 32 psi on the rear tires, that's actually an easy way to get more rear grip and reduce the chance of oversteer. Plus, it probably makes the ride a little better.
