Here is my 6th Ferrari run:
I am extremely happy. To be honest I have had a terrible time understanding the handling dynamics of the car since I bought it. It has a tendency for severe understeer, which I mostly blamed on myself not knowing how to drive a mid-engine car.
This time I put 5 psi more pressure in the rear than the front (R: 42 psi, F: 37 psi) (RE-11As), which completely eliminated the understeer, in fact, probably gave it slightly too much oversteer. It was awesome; much more “BMW-like” but with this wonderful sense of rotation around a center of gravity further back of the car. It was pretty cool.
Now that I’ve got that going, I’ll probably back off the pressure differential over time as I get better at driving the car. (I have given up at being good at autocross.)
