Will you be at the ring over the weekend? I will arrive tomorrow and stay through Sunday. I drive a dark grey E90 with Düsseldorf-Plates.
I just increased the front camber to the max and will test how it feels. Should be something between 1.3 and 1.5 deg, I presume. Is this something you already did?
On my previous car bigger sway bars were a great improvement on the handling.
