The car's come from BMW pumped up to nearly max tire pressure (high 50's-low 60's). When the tech's take the new cars in for PDI they take the spacers out of the suspension & deflate the tires.

I feel the car understeers at 32F / 38R.
I am now running 36F / 38R and see if that makes a difference.
The stock values are set up to understeer since understeer is a lot easier to manage than oversteer. The closer you get to even front-back pressures, the more neutral your car will seem.

I run 36/38 on my ZHP now and it's pretty ideal & neutral feeling.
